摘　　要：对水质总磷测定过程中色度浑浊度去除干扰进行研究,分别研究了补偿法、过滤法、稀释法三种方法,分析了补偿法对消解后有色度无浑浊度的水样去除干扰效果;分析了补偿法对消解后有浑浊度的水样去除干扰效果;分析了补偿法对消解后有浑浊度水样不同磷含量情况下去除干扰效果;分析了稀释法在消解后浑浊度较大情况下去除干扰效果;分析了过滤法在消解后浑浊度有无两种情况下去除干扰效果;比较了补偿法和过滤法在不同浑浊度情况下的适用范围。In the process of determination of turbidity ,the removal ofchroma interference of phosphorus in water were studied, there methods arc＇ studied which are compensation method, filtration method and dilution method, Analyzed the compensation method applied to remove interference effect which has chroma and no turbidity in the water sample; Analyzed the compensation method applied to remove interference effect which has turbidity in the water ; Analyzed the compensation method applied to remove interference effect which has different phosphorus content and turbidity in the water; Analyzed the dilution method applied to remove interference effect which after has large of disturbance after digestion; Analyzed the filtration method applied to remove interference which has turbidity and nu turbidity. Finally compared the compensation method with the filtration method in different turbidity conditions.
