| Abstract: | Six cyclo-carbonate extractants of a series have ho synthesis. Their extraction properties, such as ex-traction sped, phase separation time, selectivity, stripping, effects of pH and diluents were examined in detail.Results indicate that the extractant series possess excellent extraction and stripping kinetics, high selectivity andstrong ability for gold. The direction of molecular design on the extlactant series is pointed out too. The extraction mechanism is also researched . Oxonium salt extraction is demonstrated, and the extraction compound is . |
