摘 要：用广角X射线衍射（XRD）和红外光谱（FT-IR）的高斯函数分峰拟合法研究了桉木浆综纤维素稀酸水解去除无定形区过程中晶型和氢键模式的变化。研究结果表明，稀酸水解前后，纤维素的结晶度和晶面尺寸增大，桉木浆综纤维素、盐酸水解桉木浆综纤维素和硫酸水解桉木浆综纤维素中分子间氢键的相对含量分别为48.15%、77.07%、55.22%，证实纤维素链间主要靠分子间氢键结合，稳定纤维素链；分子内氢键处于辅助地位。稀盐酸水解纤维素无定形区前后，分子内氢键的强度分别从10.05%下降到4.19%，41.78%下降到18.74%，分子间氢键的强度则从48.15%上升到77.07%。稀硫酸水解纤维素无定形区前后，分子内氢键强度分别从10.05%下降到7.63%，41.78%下降到37.15%，分子间氢键强度则从48.15%上升到55.22%。稀酸水解前后，纤维素的晶型不变，只是发生氢键类型的相互转化。

Abstract：The change of crystalline form and hydrogen bonding patterns of holo-cellulose during dilute acid hydrolysis process was analyzed by X-ray diffraction and FT-IR spectroscopy. The FT-IR spectra of hydrogen-banded OH stretching vibration were resolved into three bands for cellulose I,assuming that all the vibration modes follow Gaussion distribution. Results showed that the crytallinity of cellulose and crystallite size increase after hydrolysis treatment. The relative contents of molecular hydrogen in three kinds of samples are 48.15%, 77.07% and 55.22%.It has been proved that cellulose chains mainly combine together by hydrogen bonding between molecules, while intramolecular hydrogen bonds are taking second place. Acid hydrolysis only influences the transformation of hydrogen bonding patterns while crystalline form has no change.

摘 要：在混合办公废纸（MOW）常规化学脱墨工艺条件下，考察了几种阳离子聚合物（CPAM、CS、PAC）对脱墨浆分散体系界面及胶体化学特性（如Zeta电位、表面张力）和浮选脱墨效果（如白度、残余油墨量）的影响，并利用扫描电子显微镜(SEM)对胶体环境改变前后脱墨浆中纤维表面形态变化与残余油墨粒子分布情况进行了分析。结果表明，在MOW脱墨分散体系中加入少量阳离子聚合物对改变体系界面及胶体化学特性有积极影响；适宜的界面及胶体化学环境有利于油墨粒子的去除；当Zeta电位在-14.0～-12.0 mV之间、表面张力在60.0～63.0 mN/m之间时，与常规化学脱墨相比，脱墨浆白度及油墨去除率均有提高。SEM图显示出加入少量阳离子聚合物可保持适宜的界面及胶体化学环境，有助于进一步去除细小油墨粒子，降低细小纤维及杂质含量，使纤维表面变得更加洁净。

Abstract：Interface and colloid characterisitics of MOW deinking pulp dispersion system were investigated. Effects of several cationic polymers (CPAM, PAC, CS) on the Zeta potential and surface tension of this pulp dispersion system under the conditions of optimal chemical deinking process were researched. At the same time, the relations between the surface and colloid characterisitic changes and flotation efficiency (brightness and residual ink particles content of the pulp) were studied. Changes of deinked pulp fibers morphology and ink particles distribution before and after changing colloidal environment were analyzed by scanning electron microscopy (SEM). The results showed that interface and colloid chemical properties can be changed by adding a small amount of cationic polymer into the deinking system.The appropriate interface and colloid at environment is conducive to the removal of ink particles.When Zeta potential is -14.0~-12.0 mV and the surface tension is 60.0 ~ 63.0 mN/m, the brightness and ink removal efficiency of MOW deinking pulp are improved compared to the optimal conventional chemical deinking by flotation.SEM images indicated that the fiber surface becomes clearer after adding a small amount of polymers to maintain the appropriate interface and colloid chemical conditions,and the small ink particles, fines and other impurities content are also reduced.

Abstract：The selective adsorption of Cr6+, Ni2+ and static absorption of Cr6+ and Ni2+ on a novel spherical chelating cellulose adsorbent (SCCA) containing caoboxyl and imidazolyl groups were studied. The results showed that SCCA has good adsorption performance for Cr6+, and follows the relation of Langmuir adsorption isotherm formula. The adsorption capacity increases with an increase of solution temperature. The saturation adsorption capacity for Cr6+ is 53.48 mg/g under the optimum conditions (60℃ of adsorption temperature, 2 hours of adsorption time, 1 of solution pH). SCCA has bad adsorption performance for Ni2+, and it follows the relation of Langmuir and Freundlich adsorption isotherm formulas. The adsorption processes of Cr6+ and Ni2+ are controlled both by models of surface diffusion process and intraparticle diffusion process in early-time. SCCA has good adsorption selectivity for Cr6+ when Cr6+ and Ni2+ are in coexistence. The adsorption selectivity parameter is 26.38 under the solution pH value 1 and the adsorption temperature 60℃.

摘 要：研究了钙离子和钠离子对造纸湿部及成纸性能的影响。研究结果表明，在不添加助剂的浆料中，金属离子使浆料滤水和留着性能提高；添加了阳离子淀粉、AKD、CPAM、硅溶胶等助剂后，金属离子会削弱浆料中功能助剂的性能，且影响浆料滤水和留着性能。钙离子对浆料的助留助滤性能的影响大于钠离子；金属离子同样影响AKD的施胶效果，钙离子对AKD施胶效果的降低作用大于钠离子；随着浆料中金属离子含量的增加，成纸的抗张强度和耐折度先增大后减小，且添加钙离子后抄成的纸张强度基本上都低于添加钠离子调节浆料至相同电导率时而抄成纸张的强度。

Abstract：In this paper, the different effects of calcium-ions and sodium-ions on wet end performance and properties of hand-sheets were investigated. The results showed that metal ions could enhance the retention and drainage ability of the pulp without any chemical aids. However when chemical aids such as cationic starch, AKD, CPAM, silica sol were added into the pulp, metal ions impaired the ability of the chemical aids and affected the retention and drainage ability of the furnish, the reduction of retention and drainage ability of the furnish caused by calcium-ions was more significant than sodium-ions. Metal ions also affected the sizing efficiency of AKD, the reducing effect of calcium-ion was stronger than sodium-ions. On the other hand increasing the metal ions content in the furnish, tensile index and folding endurance of the hand-sheets increased at first and then decreased, sodium-ions was superior to calcium-ions in hand-sheets strength when the conductivities of the furnish were the same.

Abstract：Surface modification of precipitated calcium carbonate with cationic styrene/acrylate was carried out. The surface structure and performance of modified precipitated calcium carbonate were characterized by DSC, FT-IR, Zeta potential, laser particle analyzer, sedimentation volume and contact angle and compared with unmodified precipitated calcium carbonate. According to the results of DSC and the spectra of FT-IR, the physical adsorption between surface modifiers and precipitated calcium carbonate took place. It was found that particle size of modified sample was smaller than unmodified one, sedimentation volume was larger and Zeta potential was higher. The results showed that the modified precipitated calcium carbonate is beneficial to improve physical properties, retention rate and hydrophobic ability of the paper when it is used as filler.

Abstract：The organic acids in the waste-liquor of aspen auto-catalyzed ethanol-water pulping were analyzed. The lignin was separated and extracted by ether. The ether extract was qualitatively analyzed by GC-MS. Results showed that there were almost 25 kinds of complex components in the waste-liquor such as acids, esters and low molecular weight lignin, the contents of acetic acid and formic acid were higher comparatively. Vacuum distillation was also used to separate lignin from the waste-liquor. All the fractions were analyzed by volumetric analysis and GC as well. It revealed that the total acid content was 0.043 mol/L. Furthermore the acetic acid and formic acid were about 1.864 g/L and 0.665 g/L respectively by the analysis of GC.

Abstract：The N-(2-aminoethyl) dehydroabietic acid amide （ADRA）was prepared from dehydroabietic acid and 1,2-ethylenediamine. The mediator ADRA-F-KL was synthesized from Kraft lignin(KL), ADRA and formaldehyde (ADRA-F-KL) by mannich reaction. The effects of reaction temperature，reaction time，the molar ratio of reactants on nitrogen contents of ADRA-F-KL were investigated. Cationic composite emulsifier(ADRA-DETA-F-KL) was prepared from ADRA-F-KL, formaldehyde and diethylenetriamine(DETA). The experiments showed that the optimum reaction conditions of ADRA-F-KL were 3h of reaction time, n(KL)∶n(ADRA)=1∶0.25, 90℃ of reaction temperature. The IR, elemental analysis and surface tension of the target product showed that the corresponding amine-methyl groups were introduced into KL by the Mannich reaction. The minimum surface tension value of ADRA-DETA-F-KL was 48.5 mN/m in dilute hydrochloric acid solution with 2 of pH value. Compared to the lignin modified by diethylenetriamine/ formaldehyde whose minimum surface tension is 57.80 mN/m，the surface activity of ADRA-DETA-F-KL is improved greatly.
