| 1 | Biosorption of Methylene Blue by Chemically Modifi ed Cellulose Waste显示文摘Citric acid modifi ed cellulose waste(CMCW) was prepared via esterifi cation and used as a low-cost biosorbent for the removal of methylene blue(MB) from aqueous solutions. The effects of biosorbent concentration, initial pH of MB solution, biosorption temperature, contact time, and initial MB concentration on the biosorption of MB were investigated using batch biosorption technique under static conditions. The experimental results showed that CMCW exhibited excellent biosorption characteristics for MB. The maximum biosorption capacity of MB was up to 214.5 mg/g at an adsorption temperature of 293 K. The removal rate of MB onto CMCW reached the maximum at pH>4 and the biosorption reached an equilibrium at about 50 min. The kinetic data can be described well with the pseudo-second-order model and the isotherm data was found to fi t the Langmuir isotherm with a monolayer adsorption capacity of 211.42 mg/g. The biosorption appears to be controlled by chemisorption and may be involved in surface adsorption and pore diffusion during the whole biosorption process. | 靳艳巧 ZHANG Yizhuan Lü Qiufeng CHENG Xiansu | 2014 | Journal of Wuhan University of Technology(Materials Science)2014，29，4： | 2 |
| 2 | Optimisation of Bio-polyol Production from Cassava Residue Using Ethylene Glycol as the Liquefaction Reagent显示文摘Cassava residue was liquefied by using ethylene glycol(EG), ethylene carbonate, propylene carbonate and polyethylene glycol(molecular weight: 400 g/mol) as the liquefaction reagent respectively at the temperature of 130-170 ℃ with sulfuric acid as the catalyst. The influences of liquefaction parameters, such as the type of liquefaction reagents, mass ratio of EG/cassava residue, liquefaction temperature and time on the properties of the products were discussed. The optimum liquefaction conditions were obtained when the mass ratio of EG/cassava residue was 6:1(w/w), the liquefaction temperature was 150 ℃, the liquefaction time was3 h and the mass fraction of concentrated sulfuric acid/EG was 2.5 wt%. The hydroxyl numbers and residue content of the liquefied products at optimal conditions were 1 137 mgKOH/g and 0.43%, respectively. FT-IR spectrum showed that the liquefaction product of cassava residue was polyether polyol and could be used to prepare polyurethane material or alkyd resins. | 康佳清 CHEN Wei YAO Yuan 靳艳巧 CHENG Xiansu Lü Qiufeng | 2019 | Journal of Wuhan University of Technology(Materials Science)2019，34，4： | 2 |

| 5 | Preparation of Bio-polyols by Liquefaction of Hardwood Residue and Their Application in the Modification of Polyurethane Foams显示文摘Hardwood residue(HR),a byproduct of paper industry,was liquefied by using polyethylene glycol 400(PEG400) and ethylene carbonate(EC) as the liquefaction solvents,and concentrated sulfuric acid as the catalyst to produce bio-polyols(HRLP),which were used to synthesize polyurethane(PU) foams.The effects of conditions on the properties of HRLP and modified PU foams were investigated and the mechanism of biomass liquefaction was discussed.The optimum conditions of liquefaction were obtained as follows: reaction temperature of 160 °C,reaction time of 60 min,ratio of PEG400/EC of 8:2(w/w),and ratio of liquid/solid of 5:1(w/w).The characterization of HRLP modified PU foams suggested that HRLP could partially replace the petroleum polyols to synthesize PU foams.With the increase of the replacement percentage of HRLP,the apparent density and compressive strength of the foams increased firstly,and then decreased.Meanwhile,the thermal stability was improved slightly. | 鹿现哲 WANG Yingchun ZHANG Yizhuan CHENG Xiansu 于岩 靳艳巧 | 2016 | Journal of Wuhan University of Technology(Materials Science)2016，31，4： | 1 |
