本文以纸上层析研究铼与钒、钼、钨的互相分离,试验以正丁醇为基而含不同络合剂与酸的十四种展开剂,结果证明,铼与上述元素分离均较好,全部展开剂都可达到此目的.其中展开剂1,2,7,13,14a等五种尚可用于四者共存时的互相分离,结果良好. 本文尚注意到展开剂中酸度不同对四者的R_F值的影响.铼、钼、钨的R_F值均随酸度增大而增大,而且铼的R_F值与酸度成直线关系.但是钒与前三者不同,其R_F值随酸度变化而改变甚少.
In this paper, paper on the rhenium and vanadium, molybdenum, tungsten separation of each other to test the n-butanol containing different complexing agent and acid fourteen kinds of developing agent, the results show that, rhenium and the above elements were more separated Good, all the developing agent can achieve this purpose .Expanding agents 1,2,7,13,14a and other five are still available for the four co-exist when the separation of each other with good results .This article also noted that the developer different acidity R_F value of rhenium, molybdenum and tungsten all increased with the increase of acidity, and R_F value of rhenium had a linear relationship with acidity.But the value of R_F of vanadium was different from the former three, Little change.
