【摘要】 采用盆栽试验,研究了改良剂(无机功能材料,MP-MCM-41)对重金属镉、铅和铜污染土壤油菜生长及土壤重金属各形态分布特征。试验结果表明,改良剂可明显增加油菜产量。改良剂对土壤的改良效果较明显,土壤重金属残留量显著提高。施加膜材料后,土壤Cd、Pb、Cu的BCR三形态中,B1态含量均降低,B3态含量增加,而B2态含量变化不显著。膜材料对Cd、Pb、Cu污染土壤具有较好的吸附钝化作用,可有效地抑制Cd、Pb和Cu在油菜体内的积累。更多还原

【Abstract】 Pot experiments were conducted to study the effect of amendment (functionalized monolayer material, MP-MCM-41) on cole growth and the forms of heavy metals in soil polluted by Cd, Pb and Cu. The results showed that the amendment increased cole dry weight significantly. The effect of the MP-MCM-41 amended the soil was markedly. The contents of Cd, Pb and Cu in soil was increased. And the MP-MCM-41 decreased the B1 contents of Cd, Pb, and Cu, while it increased the B3 contents of the metals in soil. It maybe concluded that the application of the amendment could effectively restrain the migration and accumulation of heavy metals, especially, Cd, Pb and Cu in soil towards the vegetable.更多还原
