摘要
为分析巢湖不同形态砷污染的程度以及分布特征,以安徽巢湖不同流域中上覆水为研究对象,利用原子荧光形态分析仪测定了砷离子的含量以及形态。结果显示:巢湖不同流域中上覆水砷含量各不相同,上覆水中总砷含量的平均值都未超过地表水砷含量的标准,上覆水总砷浓度为4.190-11.014ug/l,三价砷浓度为0.684-6.336ug/l,五价砷浓度为2.456-7.832ug/l。巢湖同一流域上覆水中,五价砷平均含量高于三价砷含量。
In order to investigate the levels and distribution of arsenic pollution in Chaohu Lake in Anhui province,the determination of Arsenic content was made by atomic fluorescence analyzer with species of overlying water as research object.The results show arsenic content of the Chaohu Lake from some rivers around the lake are different.The concentration of total arsenic is 4.190-11.014 ug/l,the concentration of trivalent arsenic is generally 0.684-6.336 ug/l,and pentavalent arsenic concentration is generally 2.456-7.832 ug/l;Chaohu in the overlying water pentavalent arsenic content is higher than trivalent arsenic content;the total arsenic content does not exceed environmental quality standard of surface water(GB3838-2002).
