摘要
试验了410#哌啶树脂对微量金的吸附性能，在ψ为5％-10％的王水介质中，Au与Cl^-可形成[AuCl^-]络阴离子，并可被410#哌啶树脂吸附．吸附物采用30g／L硫脲溶液解吸后，进行原子吸收光谱测定，方法经金管理样测定试验，结果与推荐值相符。
This essay refers to the test in which absorbability for microscale gold is conducted through 410# piperidine resin. In the aqua regia medium with Ф content of 5% to 10%, Au and cr forms into complex anions [Au Cl^-],and are absorbed by 410# piperidine resin. After the absorbed substances are subject to adsorption stripping with 30g/L sulfourea solution, atomic absorption spectrum is conducted for them. This method is tested by means of determination test with administrative sample of gold, and its test result conforms to the value recommended, consequently, the method can be used in the determination of microscale gold in the specimen of rock minerals.
