三乙烯四胺改性榴莲壳吸附水溶液中的Cd^2＋、Pb^2＋
Adsorption of Cd~（2＋） and Pb~（2＋） from Aqueous Solutions by Triethylenetetramine Modified Durian Shell
摘要
Abstract
The new modified durian shell（DS） adsorbent has been prepared by using triethylenetetramine and the adsorption behavior of Cd2＋ and Pb2＋ on durian shell was studied.It showed that pH 6.0 and shaking time 120 min were the optimal conditions for adsorption of Cd2＋ and Pb2＋.The adsorption capacity of adsorbent could be greatly improved after modified.The maximum adsorption capacity of Cd2＋ and Pb2＋ reached up to 30.30 and 53.76 mg/g,respectively.The adsorption process followed a pseudo-second order equation and the equilibrium isotherm was best described by the Langmuir model rather than the Freundlich model.关键词
