改性活性炭在高色度废水六价铬测定中的应用

摘要:
通过研究双氧水改性活性炭对染料的吸附能力可知,pH值为8.5~10.5时,改性活性炭可很好地去除色度且不影响六价铬的测定。在测定六价铬时,活性炭用量与废水色度之间呈指数正相关,其工作曲线可用标准曲线代替并满足质控要求。

Abstract:
According to the investigation on the adsorbability of H2O2 modified active carbon, the results show that in the alkaline condition (pH between 8.5 and 10.5), decolorization using the modified active carbon is effective and does not influence the measurement of chromium VI. The amount of active carbon needed for decolorization is exponential to the color intensity of the effluent, whose working curve can be replaced by standard calibration and meet the requirement of quality control.
