矿石中金的分离、富集通常采用活性碳吸附法、聚氨脂型泡沫塑料吸附法、离子交换法、纤维素吸附法、萃取色层分离法等。TBP萃淋树脂分离法是近几年出现的新型的分离方法。该法与其他方法相比具有简单快速,色层柱制备要求不严格,分离效果好等优点。本文拟定了TBP萃淋树脂分离富集金,以氢醌容量法测定矿石中金的方法。经实验证明,该法简单快速,准确度高,选择性较好,适用于矿石中金的测定。
Ore in gold separation, enrichment usually activated carbon adsorption, polyurethane foam adsorption, ion exchange, cellulose adsorption, extraction chromatography separation. TBP extraction resin separation method is the emergence of a new type of separation method in recent years. The method compared with other methods has the advantages of simple and quick, chromatography column preparation requirements are not strict, the separation effect is good. This paper developed a method for the separation and enrichment of gold by TBP extraction resin and the determination of gold in ores by hydroquinone volumetric method. The experiment proved that the method is simple and fast, high accuracy and good selectivity, suitable for the determination of gold in ores.
