The Influence of Coexisting Ions on Adsorption-Flotation of Pb2+ in Water by Gordona Amarae

Abstract:

Processing waste water of heavy metals by biosorption-flotation was effected by many factors. Existing coexisting ions in waste water is a important factor. The influence of coexisting alkaline-earth metals ions and heavy metals ions of Cd ²⁺, Cu ²⁺, Hg ²⁺, Zn ²⁺, As ³⁺, on results of adsorbing and floating Pb2+ in waste water was examined by using Gordona amarae as adsorbent and laurylamine as collector. The results showed that different sort of heavy metals ions and alkaline-earth metals ions have different influences on biosorption-flotation. The influences on biosorption-flotation by coexisting ions showed that ions exchange mechanism, surface complexation mechanism, oxidation-deoxidize and inorganic micro precipitation mechanism exist probably
