讨论了用聚胺脂泡沫塑料吸附分离金,研究了吸附过程中时间、温度、酸度的最佳条件。吸附分离后的金转入王水溶液中用ICP—AES法测定,研究结果表明该方法能大大降低基体干扰,提高分析测定准确度,能很好地应用于云南省高硫高砷复杂基体金精矿的分析测定。
Discussed the use of polyurethane foam plastic separation of gold, adsorption time, temperature, acidity of the best conditions. Adsorption and separation of gold into the aqua regia solution by ICP-AES method, the results show that the method can greatly reduce the matrix interference and improve the accuracy of analytical determination, can be well applied to high sulfur and high arsenic in Yunnan complex gold matrix Mine analysis and determination.
