Abstract
A new simple, fast and sensitive differential pulse voltammetric method was developed for the determination of different aliphatic phthalates. Dibutyl phthalate, diethyl phthalate, didecyl phthalate, and diallyl phthalate can be determined in 0.1 M tetramethylammonium bromide in methanol using a hanging mercury drop minielectrode and a meniscus modified silver solid amalgam electrode. Optimum conditions were found including concentration and composition of supporting electrolyte and solvent, scan rate, pulse amplitude, pulse width, etc. Linear calibration curves were obtained for 10-5 and 10-6 M and for hanging mercury drop minielectrode also for 10-7 M.
