本文报导了1983年8月于浙江沿岸采集的两个第四纪柱状样品中重金属的形态和分布,并采用连续提取法,将沉积物中重金属分成六种形态:即水可溶态;氯化镁可交换态;碳酸盐结合态;铁锰水合氧化物结合态;有机质结合态;残余态。然后分别用阳极溶出伏安法和原子吸收分光光度法测定。
This paper reports the morphology and distribution of heavy metals in two Quaternary columnar samples collected along the coast of Zhejiang in August 1983 and uses continuous extraction to separate the heavy metals in the sediments into six forms: water-soluble; magnesium chloride Exchangeable state; Carbonate bound state; Fe-Mn hydrated oxide bound state; Organic matter bound state; Residual state Then by anodic stripping voltammetry and atomic absorption spectrophotometry.
