Abstract

A simple and rapid procedure for sulphide measurement in crude oil refinery wastewater has been developed. This method is based on the knowledge of the UV response of sulphur compounds and the mathematical deconvolution of the sample spectrum using reference spectra (specific compounds or aggregate spectra). The detection limit of the method is 0.5 mg l(-1) for a quartz cell pathlength of 10 mm. The range is up to 15 mg l(-1). The method has been validated for crude oil refinery wastewater. Compared to conventional methods, the UV determination is quicker and easier to run.

摘要

已开发出一种用于测定原油精炼厂废水中硫化物的简单快速方法。该方法基于对硫化合物紫外线响应的了解，以及使用参考光谱（特定化合物或总光谱）对样品光谱进行数学反卷积。对于10毫米的石英池光程，该方法的检测限为0.5毫克/升。测量范围高达15毫克/升。该方法已在原油精炼厂废水检测中得到验证。与传统方法相比，紫外线测定法更快且更易于操作。
