Description

Different systems consisting of a reagent and a fibrous absorbent filled with an anion exchanger were studied in determining molybdenum(6) by solid-phase spectroscopy. A system of a fibrous adsorbent filled with a AV-17 anion exchanger and phenylfluorine was selected and studied. The system provides the determination of molybdenum with a detection limit of 0.002 mg/l in the presence of different cations that usually interfere with the determination. A procedure for determining molybdenum (RSD < 15 %) was developed verified in analyses of river, well, and tap water. The analysis takes 15-20 min

Abstract (Russian)

Исследованы различные системы реагент-волокнистый сорбент, наполненный анионобменником, для определения молибдена(6) твердофазной спектроскопией. Выбрана и изучена система: волокнистый сорбент, наполненный анионобменником АВ-17, - фенилфлуоран, которая позволяет определять молибден с пределом обнаружения 0.002 мг/л на фоне многих обычно мешающих катионов. Разработана и апробирована при анализе речной, колодезной и водопроводной воды методика определения молибдена (sr < 0.15). Продолжительность анализа 15-20 мин
