Abstract
Изучено взаимодействие Zr (IV) с арсеназо III в твердой фазе. Установлены оптимальные условия реакции и состав образующегося на поверхности комплекса, предложена схема взаимодействия на границе раздела фаз. Разработана методика твердофазного спектрофотометрического определения Zr (IV) с пределом обнаружения 0,06 мкг/см3.
The interaction of Zr (IV) with arsenazo III in the solid-phase was studied. The optimum conditions of the reaction and the composition of complex that is formed at the surface were found, and a scheme was proposed for the interaction at the phase boundary. A solid-phase spectrophotometric procedur was developed for determination of Zr (IV) with detection limit of 0.06 g/sm3, respectively.
