摘要
探索了马铃薯淀粉黄原酸酯基高吸水树脂对Ni 2+、Co2+、Zn2+和Cu2+的二元混合溶液的平衡吸附,并对吸附机理进行了初步研究。结果表明:树脂在二元混合溶液中对Cu2+具有较好的选择性吸附能力。当树脂投放量为0.1g、金属离子初始浓度为100mg/L时,马铃薯淀粉黄原酸酯基高吸水树脂对Cu2+的吸附容量可达78.27mg/g。该高吸水树脂对重金属离子的静态吸附过程符合准二级动力学方程,且与高吸水树脂表面的物理吸附有关。
The equilibrium adsorption of potato starch xanthate superabsorbent resins on Ni ^2＋,Co^2＋,Zn^2＋and Cu^2＋in two mixed solution was explored,and the adsorption mechanism was studied.The results showed that：the resins had good selective adsorption ability to Cu^2＋in two mixed solution.When the resin amount was 0.1g,initial metal ion concentration was 100mg/L,the adsorption capacity of resin for Cu^2＋up to 78.27mg/g.Static adsorption process of the absorbent resin for metal ions conformed to quasi two-level dynamic equation,and associated with the surface physical adsorption of super absorbent resin.
