説明

The removal of Hg²⁺ has been studied by the flotation technique. Ethyl xanthate and ethyl aerofloat were used as collectors forming insoluble and hydrophobic Hg²⁺ salts. The solutions containing 1.0 or 10.0ppm of Hg²⁺ were treated with collectors by a Denver Sub A type. flotator, then the residual solutions were analysed spectrophotometricaly by the dithizon method. By the flotation technique, it was found that residual Hg²⁺ concentration was reduced to 0.06ppm while by the filtration technique it was below 0.02ppm. The effect of coexistence of metal ions such as Fe²⁺, Cu²⁺, Zn²⁺ and Cd²⁺ on the removal of Hg²⁺ was also examined and the removal of Hg²⁺ was found to be prevented to a certain extent by these metal ions. However lower xanthate and aerofloat were found to be suitable for the removal of Hg²⁺ from the waste water containing these other metal ions.
