Flow Injection Analysis with Tensammetric Detection for the Determination of Detergents
نویسندگان
چکیده
A straightforward flow injection method for the tensammetric determination of surfactants is described. The flow-through cell is equipped with a mercury-coated gold electrode as the working electrode. Ionic as well as nonionic surfactants can be determined in the concentration range 10~5-104 M. The calibration graph is not linear but with an approximation by a polynomial or a cubic spline function, correct results can be obtained with an accuracy of *4%. The sample rate is about 60 h-l.
