摘要/Abstract

摘要： 基于比值-导数光谱的基本原理提出了一种测定碱性过氧化氢机械浆（APMP）制浆废水色度的新方法，检测结果不受pH值和废水中悬浮物的影响，255 nm可作为比值-导数光谱测定色度的检测波长，当待测样品的色度值范围在50～1 130 度之间时，准确值与预测值之间的相关系数为0.996 4，相对偏差在±8%之内。与传统色度检测方法相比，新方法操作简便，降低了人为因素造成的误差，且无需消耗化学试剂，可以满足APMP制浆废水色度的测定要求。

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.

Key words: pulping effluent, ratio-derivative spectrometry, chroma, high yield pulp
