重金属镉是水中重要污染物之一。水中痕量镉的分析,首先常用富集技术。近年来,发展起来的巯基富集分离技术,在环境分析中有明显的优越性。应用这种技术,可实现在现场进行采样、富集和分离。 二龙湖是我省第二大湖,是四平市的重要鱼业生产基地,又是下游水田灌的主要水源,将来也将是四平市饮用水的主要水源。监测二龙湖水的污染情况,保护二龙湖水,是当务之急。
Heavy metal cadmium is one of the important pollutants in water. Analysis of trace cadmium in water, the first commonly used enrichment technology. In recent years, the development of the mercapto-rich separation technology, environmental analysis has obvious advantages. Application of this technology can be carried out in the field sampling, enrichment and separation. Erlong Lake is the second largest lake in our province and an important fish production base in Siping City. It is also the main source of water for irrigation in downstream paddy fields and will also be the main source of drinking water in Siping City in the future. Monitoring the pollution of Erlong Lake and the protection of Erlong Lake is a top priority.
