摘要
采用BCR连续提取分类法,结合透射电镜、X-ray粉末衍射光谱、红外光谱、原子吸收光谱和相应的化学法等手段,综合分析了山东小清河济南段底泥沉积物的形貌,主要和次要成分的化学组成,并探讨了在BCR分级提取的各个阶段中被提取的底泥试样污染物Cu,Pb,Zn,Cr,Cd的分子存在形态。同时发现污染区底泥试样中硅酸盐晶格内污染元素含量均较本底试样有规律地增加。
Electronic microscopy,X-ray diffraction,infra\|red spectrometry,atomic absorption spectrometry and chemical analysis are used for a comprehensive analysis of the exterior form and the primary,secondary and small component parts of the sediment samples collected from Xiaoqing River in Jinan,Shandong Province.Then with the incorporation of BCR's sequential extraction procedures,a comprehensive analysis and a detailed discussion are made of the molecular forms of the trace metal pollutants such as Cu,Pb,Zn,Cr and Cd in each fractions of the BCR's fractions scheme.It is found that the concentration of the pollution metals in the siliceous crystals in the residual increases regularly with the increase of the concentration of the relevant pollution metals in the sediment.
