【摘要】 采用静态水培试验的方法,研究绿萝对不同浓度铅、铬污染水体的净化效果。结果表明绿萝对Pb污染浓度小于1 mg/L的水体有明显的净化效果,Pb的去除率在41%以上,当Pb污染浓度大于5 mg/L的时,绿萝对Pb的去除率趋向于零;绿萝对Cr污染浓度小于1 mg/L的水体有明显的净化效果,Cr的去除率在17%以上,当Cr浓度大于5 mg/L时,绿萝对Cr的去除趋向于0。研究表明,绿萝在净化低浓度Pb,Cr污染的水体方面有较好的应用前景,并且对Pb的去除作用更加明显。更多还原

【Abstract】 A hydroponic experiment with different concentration of Pb, Cr pollution water was conductde to study the purification effect of Scindapsus Aureus. The results showed that Scindapsus Aureus have obvious purification effect on pollution water that concentration of Pb less than 1 mg/L, the removal rate of Pb in more than 41%, When the concentration of Pb in water is greater than 5 mg/L, Scindapsus Aureus for the removal rate of Pb tends to zero; Scindapsus Aureus have obvious purification effect on pollution water that concentration of Cr less than 1 mg/L, the removal rate of Cr in more than 17%, When the concentration of Cr in water is greater than 5 mg/L, Scindapsus Aureus for the removal rate of Pb tends to zero. Research shows that, Scindapsus Aureus has good application prospect in purification water of low concentration of Pb,Cr. And the more obvious on the removal effect of Pb.更多还原
