摘要
文章采用改进的化学连续提取法,将所提取的黄河中游(包头河段、临河河段)沉积物中的样品用磷钼蓝分光光度法测定其中六种形态磷的含量,以便为该河段防治水污染提供基础依据。测定结果表明:(1)黄河包头段、临河段沉积物中的磷主要以钙结合磷和有机磷为主;(2)包头河段六种化学形态排序:Ca-P>Org-P>Al-P>Fe-P>Ex-P>Obs-P,临河河段沉积物中磷的六种化学形态排序:Ca-P>Org-P>Al-P>Ex-P>Fe-P>Obs-P。
Different sections of the Yellow River sediment phosorous in the six chemical speciation analysis, the results of the analysis showed. （1）Baotou reachs of Yellow River, Linhe River sediment phosphorous mainly phosphorous and calcium-binding organophosphate-based; （ 2 ）Baotou Reach chemical speciation of the six ranking： Ca-P〉Org-P〉Al-P〉Ex-P 〉Fe-P〉Obs-P. Linhe River sediment phosphorous chemical form in the six ranking： Ca-P〉Org-P〉Al-P〉Ex-P Fe-P 〉 Obs-P.
