Влияние степени дисперсности пищевых добавок на совместную сорбцию свинца и кадмия

Влияние степени дисперсности пищевых добавок на совместную сорбцию свинца и кадмия

Abstract

Методами спектрального анализа изучен процесс сорбции свинца и кадмия из растворов их солей пищевыми добавками «Биофит» различной степени дисперсности. Исследовали как совместную сорбцию тяжелых металлов, так и по отдельности. Увеличение степени дисперсности криопорошков существенно влияет на их способность сорбировать свинец: последняя возрастает в 1.5-2 раза по сравнению с крупнодисперсными криопорошками. Способность сорбировать кадмий в пределах погрешности эксперимента остается неизменной. Исследование совместной сорбции обоих металлов из растворов их солей показывает, что между металлами существует антагонизм.

The sorption of lead and cadmium from their salt solutions by food additives «Biofit» of various degree of dispersity has been studied by spectral analysis methods. Both the joint sorption of heavy metals and individual ones have been investigated. An increase in the cryopowder dispersity substantially affects cryopowder ability to sorb lead. It becomes 1.5-2 times higher than that of coarsely-dispersed cryopowders. The ability to sorb cadmium remains invariable within the experimental uncertainty. The joint sorption study has shown the existence of antagonism between the metals.
