摘要
悬移质在河流的砷以及重金属转化迁移中起着非常重要的载体作用,因此,研究悬移质吸附的影响因素,对确定河流中砷以及重金属污染状况有一定的指导意义。文章分别从温度、含沙量、水体、pH值、悬移质中有机质含量等方面对悬移质中砷的影响进行了研究,并部分的验证了前人对悬移质吸附影响因素的理论。
The suspended sediments play the extremely important role of arsenic transformation migration in the rivers, therefore, it could determined the distribution of arsenic in the rivers and also has some guiding sense that research on the influence factors of the suspended sediments adsorption. It conducted the research that the arsenic influence aspects from the temperature, the silt content, pH value, the organic content and so on. As the same time, it also has partly confirmed the adsorption theory.
