| 摘 要： | 采用连续提取法研究了福建省酸性耕作土壤中Zn、Cd、Cu、Co、Ni和Pb的形态分布及其影响因素.结果表明,各元素水溶态和交换态所占比例均很小,Zn、Co、Ni和Pb均以残渣态和铁锰氧化物结合态为主,Cu以残渣态和有机结合态为主,Cd以碳酸盐结合态与专性吸附态、铁锰氧化物结合态和交换态为主.相关分析表明,土壤理化性质对重金属形态有较大影响,但影响程度因元素而异.Zn、Ni和Co的形态受游离氧化铁、阳离子交换量和粘粒含量的影响较大;Cd和Pb的形态受土壤pH、游离氧化铁和粘粒含量的影响较大;Cu的形态与土壤粘粒含量呈较显著相关.

| Abstract: | The fractions of Zn,Cd,Cu,Co,Ni and Pb in some acid cultivated soils in Fujian Province,China were extracted by a sequential extraction procedure and the factors influencing the fractionation were discussed.The results showed that the proportions of water-soluble and exchangeable fractions to the total contents of the metals were quite small.Zn,Co,Ni and Pb were dominated by residual and Fe-Mn oxide-bound fractions;Cu was dominated by residual and organic-bound fractions,whereas Cd was dominated by exchange... |
