摘　　要：铬是皮革业废水中最主要的污染元素,为了快速准确地检测皮革业废水中的总铬含量,本文介绍了一种检测皮革业废水中总铬含量的X射线荧光光谱法,方法检出限为0.22 mg/L,低、中、高三组实际样品重复试验的相对标准偏差均小于8%,加标回收率的范围是90%~110%。该方法具有良好的精确度和正确度,与传统检测方法相比是一种快速、高效、准确的检测方法。Chromium is the most important pollution element in leather industry wastewater. In order to quickly and accurately detect the total chromium content in leather wastewater, an X-ray fluorescence spectrometry was established to detect the total chromium content in leather industry wastewater. The detection limit of the method is 0.22 mg/L. The relative standard deviation of the three groups of actual samples is less than 8%, and the recovery rate is 90%-110%. The method has good accuracy and trueness,compared with the traditional detection method, it is a fast, efficient and accurate detection method.
