A intercalated TiO2photocatalyst loaded bentonite was prepared by sol-gel method. The effect of reaction time, reaction temperature,the amount of butyl titanate and other process parameters on prepared material of degradation of methyl orange,as well as the relationship between the concentration of methyl orange on degradation process and illumination time were discussed by single factor method.The results showed : the first absorbance of the intercalated TiO2photocatalyst loaded bentonite material was 0.342 and the average absorbance was respectively 0.7402 through 5 washing after the intercalated TiO2photocatalyst loaded bentonite irradiated at UV-irradiation 1.5h to 20mg/L methyl orange.

High water absorption material was prepared by graft copolymerization of calcium lignin sulphonate with acrylic acid and acrylamide. Effect of process parameters on graft copolymerization and sample properties was investigated by means of the single-factor method, and the microstructure of fracture surface of the water absorbent resin was analyzed by SEM. The result shows that: when mass percents of acrylic, acrylamide, calcium lignin sulphonate, initiator and crosslinking agent are 65.5%, 19.5%, 15%, 0.09%, and 0.05%, respectively, and neutralization degree is 60% with 2h of initiation reaction time and 1.5h of crosslinking reaction time. The water absorption rate of material is up to 1010g/g, and 0.9wt% NaCl solution absorption rate is up to 110g/g.
