摘要
通过研究样品水、邻苯二甲酸氢钾和某些无机阴离子等溶液的紫外吸收情况,发现用紫外积分吸收值(ΣA)表征水中污染物总含量,具有测试方便、快速和测试费用低廉等特点。ΣA可作为一项水污染的预警指标,当ΣA大于16.86时,预示着水的COD值将超标;而当ΣA值大于173.8时,预示着水的硝酸盐含量将超标。
The ultraviolet absorption spectrum of some samples of water,potassium hydrogen phthalate and some inorganic anions were studied.The total of pollutant content in the water can be characterized by the ultraviolet integral absorption（ΣA）.This method of quantitative analysis was quicker,easier and cheap.The ΣA is a foreshowing index of the water pollution.The COD of water perhaps superscales when the ΣA exceeds 16.86.The nitrate of water perhaps superscales when the ΣA exceeds 173.8.
