| Abstract: | A new polymer chelating fibre-rhodanine fibrewas synthesized and its analytical performance for the enrichment of gold has been studied in detail. The results show that the proposed fibre is highly stable in structure and can adsorb gold even from aqua regia solution. The saturated adsorption capacity is as high as 465mg gold/g. Even with a flowrate of 50mL/min through the column, gold can be recovered completely owing to the high selectivity of the adsorption, the enrichment can be carried out in the presence of large amounts of coexisting elements. A method for the determination of gold in geological samples is proposed. |
