摘要
为消除测定染色废水色度的主观误差，采用分光光度法测定染色废水的色度，与稀释倍数法相比，具有精确、重现性好、运用范围广等特点。ｐＨ值对色度的测定有明显影响，控制ｐＨ值为７．６０，测定色度具有可比性。
It was studied to measure colourity in dye wastewater by spectrophotometry. Comparing with dilution multiple method, spectrophotometry offers good precision and repeatability (relative error below 2.2 %)and wide range of application.
