通过偶合反应将1,5—二—(2—噻唑)甲(?)接到苯乙烯—二乙烯苯的骨架上,得到一种含氮、硫配位原子的螯合树脂(1)。该树脂1对Au~(3+)的吸附容量最高达1.1mmol/g。吸附在树脂上的金络离子可以用5％硫脲——盐酸(0.1mol/L)溶液进行洗脱,回收率为84％。对pd~z+可被5％硫脲——0.1mol/LHCI热溶液定量洗脱。
The coupling of 1,5-bis- (2-thiazolyl) methyl (?) To the styrene-divinylbenzene skeleton results in a chelating resin (1) containing nitrogen and sulfur atoms. The adsorption capacity of this resin 1 to Au ~ (3+) was up to 1.1 mmol / g. Gold ions adsorbed on the resin can be eluted with 5% thiourea - hydrochloric acid (0.1mol / L) solution, the recovery rate was 84%. The pd ~ z + 5% thiourea - 0.1mol / LHCI hot solution quantitative elution.
