Abstract:

The effect of turbidity removal methods，pH and hues on the chroma measurement of industrial wastewater has been investigated，and the relationship between dilution ratio （DR） and ADMI values has been analyzed. The results show that the 0.45 μm filter membrane is more suitable for turbidity removal before chroma measurement. When pH is in the range from 6.0-9.0，the effect of pH difference on the chroma could be negligible.In addition，the correlation between the DR and ADMI values bears no relation to hues，DR =0.19 ×ADMI31（R2＞0.991）.

Key words: chroma, industrial wastewater, dilution ratio

摘要：

考察了浊度去除方法、pH及颜色对工业废水色度测定的影响,分析了稀释倍数与ADMI值的关系。研究结果表明0.45μm滤膜过滤更适于去除色度测定前的浊度。当pH为6.0~9.0时,pH对色度的影响较小。此外,稀释倍数与ADMI值的相关性与颜色种类无关,稀释倍数=0.19×ADMI31(R2>0.991)。
