摘要
以马铃薯淀粉黄原酸酯为原料制备高吸水树脂,并对其吸附Pb2+的动力学和吸附热力学行为进行了研究.结果表明:马铃薯淀粉黄原酸酯基高吸水树脂在初始浓度100mg/L溶液中对Pb2+的吸附在200min后基本达到吸附平衡,吸附容量高达80.65mg/g.该高吸水树脂对Pb2+的静态吸附过程符合准二级动力学方程和Langmuir等温吸附方程,且吸附是一种自发过程.
High water absorbent resin was prepared using potato starch xanthate as raw materials,and its adsorption kinetics and thermodynamic behavior of Pb^2＋ solution were studied. The resuits show that the adsorption of potato starch xanthate superabsorbent resin for Pb^2＋solution after 200rain reaches the adsorption equilibrium with the initial Pb^2＋ concentration at 100mg/L,and the adsorption capacity attains 80.65mg/g. Static adsorption process of the high water superabsorbent resin for Pb^2＋ meets the quasi two level dynamic equation of the Langmuir isotherm and the adsorption is a spontaneous process.
