  • 摘要: 为寻求一种有效去除蚕沙中重金属的方法，本试验研究了介质pH、强化剂种类、电压梯度等因素对蚕沙中重金属电动修复去除的影响，并通过正交试验结果进一步确定蚕沙中Cd的最佳去除条件.结果表明，随着介质pH1-7，蚕沙中Cd的去除率表现出先增加后减小的趋势，最佳介质pH值为2，去除率为71.6%；7种强化剂对蚕沙中Cd的去除效果为：EDTA > 柠檬酸 > 醋酸 > 酒石酸 > 草酸 > EDTA二钠 > EDTA铁钠.在此基础上进一步探究EDTA的最佳添加浓度为0.1 mol·L-1，Cd去除率为76.9%.随着电压梯度增大，蚕沙中重金属Cd的去除率逐渐增大，最佳电压梯度为0.5 V·cm-1.正交试验结果显示，电动修复法去除蚕沙中重金属Cd的最佳条件为：电压梯度0.5 V·cm-1，介质pH值为2，EDTA强化剂添加浓度为0.1 mol·L-1.
    Abstract: To explore an effective method for heavy metals removal from silkworm sand, the influence of pH values, enhancing reagents, voltage and other factors on the Cd removal from silkworm by electrokinetic remediation technology were evaluated in this study. The optimum removal condition of heavy metals from silkworm was determined by further orthogonal design. The results showed that the removal rate increased at first and then decreased with the change of medium pH from 1 to 7. The optimum pH value was 2, with the removal rate was 71.6%. The removal efficiency of Cd by the seven enhancing reagents was EDTA > citric acid > acetic acid > tartaric acid > oxalic acid > disodium EDTA > sodidum EDTA. The optimum concentration of EDTA was 0.1 mol·L-1, with a removal rate of 76.9%. The removal rate of Cd increased gradually with the increase of voltage gradient, with the optimum voltage gradient of 0.5 V·cm-1. The orthogonal design results showed that the electric repair method could effectively remove Cd from the silkworm, with 0.5 V·cm-1 voltage gradient, under pH 2 of the medium; and with 0.1 mol·L-1 EDTA enhancer added.
