【摘要】 <正> 以聚三氟氯乙烯粉等为载体、磷酸三丁酯(TBP)为固定相的反相萃取色层法分离矿石中的少量金已有报导。但色层柱制备麻烦,使用寿命短。由于萃淋树脂具有萃取剂流失量小,性能稳定、使用方便等特点,近来已应用于分析化学中。为此,我们合成了TBP-萃淋树脂,并研究了它对金的吸附行为,用孔雀绿萃取光更多还原

【Abstract】 A synthetic method is described for the preparation of TBP-containing resins. The unique character of the resin shows the high selectivity for gold and its longevity in use. The gold is determined by malachite green extractive spectrophotometric method. The absorbance of organic phase is measured at 630 nm. No significant interference was caused by Ca, Mg, Fe(Ⅲ), Al, Cu(Ⅱ), Ni(Ⅱ)and Co(Ⅱ)in 100—200 fold excess relative to Au(at 100μg in the aqueous solution).更多还原
