汉江中上游水体中重金属含量的测定研究

Measuration of Heavy Metals in Hanjiang River

汉江是襄樊市最大的河流,是市民饮用水的主要来源。近年来由于工业的发展,原本洁净的汉江逐渐变得浑浊,特别是工业废水中重金属的注入更是严重污染了汉江水。本研究取市内的鱼梁洲、明珠广场、襄阳城墙、小北河码头4处的汉江水中铬和锰2种重金属元素为研究对象,采用分光光度法测定汉江水中铬和锰这2种重金属的含量。研究结果表明汉江中上游水体中,铬含量符合国家饮水水质标准,而锰含量不符合国家饮水水质标准。

Hanjiang river is the biggest one in Xiangfan.It is a main source for drinking.With the industrial development,the water becomes more and more dirty.The heavy metals in the industrial waste polluted it seriously.The Manganese and Chrome contents of Hanjiang water in YuLiangZhou dock,MingZhuGuangChang dock,XiangYangChengQiang dock and XiaoBeiHe dock was studied in the paper.It was shown the content of Chrome comply with Chinese potable water standard,while the content of Manganese does not conform to Chinese potable water standard.
