研究了用二安替比林甲烷参与的阴离子相间的交换反应以提高萃取的选择性。 我们研究了从氯化物—高氯酸盐溶液中(1—4MHCl和0.5—1.5MNa℃lo_4)用二安替比林甲烷的氯仿溶液萃取分离金(Ⅲ)。在有高氯酸根离子存在的条件下,可抑制除铊(Ⅲ)外其它元素酸基络合物的氯化物被萃取。用二安替比林甲烷从氯化物高氯酸盐溶液中萃取分离金(Ⅲ)有很高的选择性,用该法可拟定两种测定金的方法:萃取络合滴定法和萃取光度法。 The exchange reaction of anions and phases involved in the diantipyryl methane was studied to improve the selectivity of the extraction. We studied the extraction of gold (III) from a chloride-perchlorate solution (1-4M HCl and 0.5-1.5MNa ° C) in a chloroform solution of diantipyrylmethane. In the presence of perchlorate ion, the chloride of other acid-base complexes other than thallium (III) can be inhibited from being extracted. There is a high degree of selectivity for the extraction of gold (III) from the perchlorate chloride solution with diantipyrine methane. Two methods of determining gold can be developed using this method: extraction complexometric titration and extraction spectrophotometry .
