| 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. |
