摘要:

］研究了梭子蟹(Portunus trituberculatus)蟹背壳与其他部位的蟹壳对水溶液中的Pb2+、Cd2+去除作用的差异，以及加入量、处理时间对其去除作用的影响.结果表明：蟹背壳对Pb2+的极限去除率可达89 %，其他部位蟹壳则为74 %；两种蟹壳对Cd2+的极限去除率均可达97 %；在加入质量分数为0.02 %、平衡10 min的条件下，蟹背壳对Cd2+的去除率约为63 %，其他部位蟹壳则为90 %.可见，不同部位的蟹壳在去除水溶液中的Pb2+、Cd2+特性方面存在明显差异

Abstract:

The adsorption differences of heavy metal ions (Pb2+,Cd2+) in aqueous solution on Portunus trituberculatus back-shell and other parts of the crab shell were studied,and the adsorption effects of the adding amount and the processing time were also studied.The results showed that for crab back-shell,the maximum removal rate of Pb2+ could reach 89 %,compared with 74 % of the other parts of the crab shell;for two kinds of crab shell,Cd2+ removal could reach 97 %.Prior to joining the amount 0.02 % under the conditions of equilibrium 10 min,the Cd2+ removal rate of the crab back-shell was about 63 %,other parts of the crab shells were 90 %.It was shown that different parts of the crab shell had obvious differences in the removal of aqueous Pb2+,Cd2+ characteristic aspects
