Description

A new method for the simultaneous determination of lead, cadmium, and mercury ions as metal tetra-(4-chlorophenyl)-porphyrin (T4CPP) chelates was developed using reversed-phase-high performance liquid chromatography (RP-HPLC) and combined with on-line enrichment technique. The linearity ranges are 0.01 - 120 μg/L for each metal chelate. The detection limits (S/N = 3) of lead, cadmium, and mercury are 2.0 ng/L, 1.5 ng/L, and 2.0 ng/L, respectively. This method was applied to the determination of the μg/L level of lead, cadmium, and mercury ions in a water sample with good results

Abstract (Russian)

Разработана новая методика одновременного определения ионов свинца, кадмия и ртути в виде хелатов с тетра-(4-хлорфенил)-порфирином (Т4ХФП) с использованием в режиме реального времени концентрирования и обращенно-фазовой высокоэффективной жидкостной хроматографии (ВЭЖХ). Диапазон линейности градуировочного графика 0.01 - 120 мкг/л для всех изученных хелатов. Пределы обнаружения (отношение сигнал/шум равно 3) для Pb, Cd и Hg равны соответственно 2.0, 1.5 и 2.0 нг/л. Методика применена для анализа образца колодезной воды
