比值-导数光谱法测定APMP制浆废水的色度
Chroma Determination of APMP Pulping Wastewater by Ratio-derivative Spectrometry
摘要
Abstract
A new method is described to measure the chroma of APMP pulping effluent by using ratio-derivative spectrometry. Adjusting the pH value and removing suspended substance before detection of chroma were not necessary in this method, and the detection wavelength was 255 nm. Precision and accuracy were suitable, and relative deviation was within ± 8 % when the chroma of samples was in the range of 50 -1 130 C. U. In contrast to the traditional methods, the present test procedure was simplified and the error caused by human factors was minimized. No other chemicals were applied during the whole test procedure and the method was an environmental friendly approach for chroma determination. Ratio-derivative spectrometry was satisfactory for the chroma determination of APMP pulping effluent.关键词
