通过试验表明了在使色层柱保持氧化气氛的条件下,铂、钯在层析过程中始终保持四价状态,它们被Kel-F-TBP吸着的牢固程度更大,便于与其它贱金属离子分离。选用4～5NHC1从柱上先单独将钯洗脱,再用0.1NHC1将铂洗脱。金(Ⅲ)在柱上吸着十分牢固。我们设计了一个长短两支柱联用的装置,上柱为短柱用以富集金;下柱为长柱,用以富集与分离钯、铂,效果良好。并藉此设计了分离和测定阳极泥和矿石中金、铂、钯的方法。
Experiments show that under the condition of keeping the color pillar column in an oxidizing atmosphere, platinum and palladium keep the tetravalent state during the chromatography, they are more strongly adsorbed by Kel-F-TBP and are easy to be mixed with other base metal ions Separated. Palladium was eluted separately from the column using 4 ~ 5NHC1, and then platinum was eluted with 0.1NHC1. Gold (III) is very strong on the column. We designed a device with a length of two columns combined, the column for the short column to enrich the gold; the lower column for the long column, to enrich and separation of palladium, platinum, the effect is good. Based on this, a method of separation and determination of gold, platinum and palladium in anode slime and ore was designed.
