摘要

采用火焰原子吸收分光光度法测定了伊宁市某片区城市地下井水、景观水样和降雪雪水中铜、锌、铁、锰等4种金属元素的含量.研究结果表明,各水样中铜、锌、铁、锰的加标回收率均在95%～105%之间.其中,井水水样中铜、锌、锰均达到Ⅰ类标准,铁达到Ⅱ类标准;景观用水水样中铜、锌、铁均达到A类标准,符合景观用水标准要求;雪水水样中铜、锌含量达到Ⅱ类标准,铁、锰含量均超出地表水水源地标准限制.通过对比3种水体样品中4种金属元素的含量,为伊宁市水体重金属的污染防治工作提供一定的理论基础.
        The contents of copper, zinc, iron and manganese in underground well water, landscape water sample, and snowfall water were determined by the flame atomic absorption spectrophotometry. The research results showed that the average recoveries of copper, zinc, iron, manganese in water samples were 95%～105%, the well water samples of copper, zinc, manganese achieved the class Ⅰ standard, Fe in well water class Ⅱ standard. The copper, zinc and iron in the water samples accorded with the class A standard and the requirements of landscape water standard. Copper, zinc contents in melted snow water samples accorded with class Ⅱ standards, iron, manganese contents went beyond the limit of surface water standard. By comparing the contents of four metal elements in three water samples. A theoretical basis for the prevention and control of heavy metal pollution in the water of Yining city is provided.
