Abstract

A method is described for the determination of trace amounts of phosphorus present in terephthaloyl chloride (TCL) . Phosphorus was extracted from the sample by distilled water . It was converted into molybdophosphoric acid, extracted with n-butyl acetate and molybdenum in the organic extract determined by catalytic polarography . Charging current compensation was employed to improve precision and detectors limit . The method enabled the determination of 0 .0005% P in TCL and the relative standard deviation was 4.2%
