Abstract

A new method of using adsorption microcrystalline phenolphthalein adsorption to separate and enrich trace cobalt has been developed. The effects of different parameters, such as the dosages of 1-(2-pyridylazo)-2-naphthol(PAN), phenolphthalein and various salts on the enrichment yield of Co2+ have been investigated. The possible enrichment mechanism of Co2+ was discussed. The results showed that under the optimum conditions, Co2+ could be quantificationally adsorbed on the surface of microcrystalline phenolphthalein in the form of the chelate precipitate of Co( )-PAN , while Mn2+,Zn2+ and Al3+ could not be adsorbed at all. Therefore, Co2+ was completely separated from the above metal ions. A new method for separation/enrichment of trace cobalt using microcrystalline phenolphthalein adsorption system was established. The proposed method has been successfully applied to the separation of Co2+ in the synthetic water samles, and the enrichment yield was 94.3%~102.2%.
