Polarographic determination of some linear alkylbenzene sulphonates
Abstract
The linear alkylbenzene sulphonate content of sewage samples has been determined by an indirect polarographic method. Recoveries made on sewage samples spiked with between 25 and 100 µg of 4-phenyldodecane sulphonate ranged from 82.0 to 104.1%, respectively, showing the method to be reliable when concentrations were of the order of 0.5 µg ml–1 or greater. This was also confirmed by recoveries made on tap water.
