核工业部北京第五研究所采用国产原料研制和合成了一种吸附回收金的新型树脂——410~#哌啶树脂。该树脂对金吸附很强,能有效地吸附各种浓度的金,吸附容量大于500mgAu/g干树脂,且选择性很高,在5—25％的王水介质和0.1—2N盐酸介质中,能从大量的铁、铝、钙、镁、铜、铅、锌、镍、钴等杂质中选择性地分离富集金。用3％硫脲溶液可以有效地从树脂上解吸金。树脂再生简便,使用寿命长。几年来,用该树脂对溶液、合金和矿石等物料中的金进行分离富集和测定,效果良好。由于该树脂性能优良,
Beijing Research Institute of the Ministry of Nuclear Industry using the domestic research and development of a raw material to synthesize a new recovery of gold adsorption resin - 410 ~ # piperidine resin. The resin adsorption of gold is very strong, can effectively adsorb various concentrations of gold, adsorption capacity greater than 500mgAu / g dry resin, and high selectivity in aqua regia 5-25% and 0.1-2N hydrochloric acid medium, Selective gold and silver can be separated from a large number of impurities such as iron, aluminum, calcium, magnesium, copper, lead, zinc, nickel and cobalt. Gold is desorbed from the resin with a 3% thiourea solution. Resin regeneration is simple, long life. In recent years, with the resin solution, alloy and ore materials such as gold separation enrichment and determination, the effect is good. Due to the excellent performance of the resin,
