Abstract
Abstract Trichlorobiphenyl is determined in the concentration range 0.004–1 mg l −1 by adsorptive stripping voltammetry at a hanging mercury drop electrode. Preconcentration is achieved by adsorption at a potential of −0.40 (V (vs. Ag/AgCl), and desorption at −1.10 V. Biphenyl interferes with the determination only when present in 5-fold molar amounts compared to trichlorophenyl. The interference of DDT is eliminated by prior treatment of the sample solution with sulphuric acid. The method was applied for the analysis of waste and natural waters, the relative standard deviation being
