An alternative method for the measurement of mineral sulphide in wastewater

A simple and rapid procedure for sulphide measurement in crude oil refinery wastewater has been developed. This method is based on the knowledge of th e UV response of sulphur compounds and the mathematical deconvolution of th e 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 ce ll 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 meth ods, the UV determination is quicker and easier to run. (C) 1999 Elsevier S cience B.V. All rights reserved.
