摘要
研究了三苯膦(TPP)泡沫的制备及其对痕量银的吸附性能。实验表明,这种泡沫由矿酸溶液中吸附银的选择性好、吸附率高。其流程简便,已用于地质样品中痕量银的测定。火焰原子吸收法的测定下限为0.01ppm。并有可能用于金属、合金及纯试剂等样品。
The preparation of TPP foam and its absorption behaviour of silver have been studied in detail. Experimental results show that TPP foam can absorb silver from mineral acid solution with high selectivity, for flame AA.S, the detection limit is 0.01ppm. The method has been applied to geochemical standard reference samples and satisfactory results were obtained,
