利用碱性染料萃取光度法测定金是目前较广泛应用的方法。在水相中形成二元络合物直接测定金亦有所报导,但是在水相中形成三元络合物测定金还尚未见到。本文提出了金-曙红-吡咯啶二硫代氨基甲酸钠三元络合物测定金的新方法,并对络合物的形成条件及其某些性质作了较为深入的研究,同时探讨了应用的可能性。一、试剂与仪器
Determination of gold by alkaline dye extraction spectrophotometry is the most widely used method. It has also been reported that the direct determination of gold by binary complexes in aqueous phase has been reported, but the determination of ternary complexes in aqueous phase has not yet been reported. In this paper, a new method for the determination of gold with gold-eosin-pyrroline dithiocarbamate ternary complex has been proposed. The formation conditions of the complex and some properties of the complex have also been studied in more depth. At the same time, The possibility of. First, reagents and equipment
