许多作者提出了利用纸层析法分离铬酸根、钼酸根、钨酸根和钒酸根的方案,但都是以上行法和下行法[1~5],或者是在处理纸[6,7]上进行展开,比较费时和复杂.作者曾试图利用圆形纸层析法分离,以期快速.结果找出2,4,6-三甲基吡啶-正己醇(正丙醇、异丙醇、正丁醇、异丁醇、正戊醇、或异戊醇)-浓盐酸(1:4:5),和丁酮-8N盐酸-硫脲(10%)(8:1:1)各展开剂都能使上述四离子完成分离,且每展开一次,仅需约2小时,比较省时.

Circular paper chromatographic method with Hsin-Hua No.1 filter paper has been used for the separation of ohromate, molybdate, tnngstato and vanadate ions.The results obtained with the solvent systems (1) sym.oollidine-heaanolooncentrated hydrochlorio acid (1:4:5) and (2) bntanone-8N hydrochloric acid-thiourea (10%) (8:1:1)are quite satisfactory.The time required for development is about 2 hours.
