摘　　要：辣木籽2种提取液在不同条件下对水中4种重金属(Cu、Zn、Pb、Cd)离子去除效果的结果表明,辣木籽盐提液对去除水中的Cu、Zn、Pb、Cd离子有一定效果,最佳浓度为10倍盐提液,最适投加量为每100 mL水样中投加1 mL的盐提液,12 h后效果达到最佳,去除效果Cu>Zn>Cd>Pb,其中Cu离子的去除率可达到66%,Zn为34%,Cd为19%,Pb为10%。辣木籽水提液去除效果较盐提液明显,最佳浓度为600 mg/L;最佳反应时间为1~2 h,实验时间段中各重金属离子间去除效果差异不显著(P>0.05),4种重金属离子最高去除率Cu为65%,Zn为75%,Cd为62%,Pb为76%。The removal effect resultsof four heavy metals （Cu, Zn, Pb, Cd）with two kinds ofmoringa seedsextract under different conditionsshowed that the salt extract of Moringa seeds had certain effect on removal of Cu, Zn, Pb, Cd ions, the optimal concentration of salt extract was 10 times, the optimum dosage per 100 mL water samples was 1mL, the optimal effect could reach after 12 h and the removal effect was Cu〉Zn〉Cd〉Pb, and the removal rate of Cu,Zn, Cd and Pb was 66%, 34%, 19% and 10% respectively.The effect of ulWapure water extract was better than salt extract, the best concentration was 600 mg/L, the optimum reaction time was 1 to 2 hours, and the removal effect of four heavy metal ionswas not significantly different duringthe experiment （P〉 0.05）.The maximum removal ofCu, Zn, Cd and Pbwas 65%, 75%, 62% and 76% respectively.
