摘    要:香草醛经Schiff反应对壳聚糖进行了修饰、研究了产物对Cu2+、Pb2+、Cd2+、Zn2+的吸附性能,同时考察了pH值、时间、温度等因素对吸附的影响结果表明,改性后的壳聚糖具有不流失,易再生的特点,且对金属离子的饱和吸附量比壳聚糖的大(改性后的壳聚糖对Cu2+、Pb2+、Cd2+、Zn2+吸附量分别为 143.5、 558.9、 357.7、178.4mg/g).

关 键 词:壳聚糖  香草醛  吸附  制备

Abstract:Chitosan was modified by vanillin via Schiff 's reaction and the resulting Product was investigated in relation to its adsorption behavior for metal ions such as Cu2 ,Pb2 ,Cd2 and Zn2 as well as the effects of pH, bine and temperature on the adsorption behavior The results indicate that the modified chitosan has higher adsorption capacities than the unmodified one (the former's adsorption capacities for Cu2 ,Pb2 ,Cd2 and Zn2 are 143.5,585.9,357.7 and 178.4mg/g) and has good kinetic properties-uneasily running off and being regenerated easily.
Keywords:chitosan  vanillin  adsorption  preparation
