| 摘 要： | 通过在河套平原五原地区建立典型剖面,对从剖面上采集的水样进行测试分析,结合地质环境特征,得出五原剖面上各地质、地貌单元条件下砷在浅层地下水的赋存形态。应用美国地质调查局专业水文地球化学软件Phreeqc进行水文地球化学模拟,对五原地区地下水Fe-As-H2O体系中砷的吸附释放趋势进行讨论,得出五原剖面上扇前洼地砷酸盐主要表现为从羟基铁上解离释放出来;而黄河冲湖积平原地下水中As主要表现为在水中解离。黄河冲湖积平原地下水中Fe(OH)3对砷释放的抑制力远远高于扇前洼地。

| Abstract: | By establishing typical profiles in Wuyuan County,collecting water samples and making analyses,and combing the geological environmental characteristics,we got to know the occurrence state of arsenic species in shallow groundwater.Using USGS professional software Phreeqc to model hydrogeochemical condition,we have discussed the adsorption and release of arsenic in Fe-As-H2O system.The trends of the arsenic adsorption and release are affected by iron oxides and hydroxide;in the depression in front of the fan,... |
