扑疟喹啉曾用于CrO42-,Ce4+,Au3+和VO3-的检定.反应均在0.1N高氯酸和8%草酸溶液中进行,溶液显紫色.在沸水浴中加热的条件下,IO3-和IO4-在1N高氯酸溶液中同扑疟喹啉作用亦显紫色.本文报告IO3-及IO4-同扑疟喹啉反应进行时的最适条件,反应灵敏度和选择性,有机溶剂对反应产物的作用以及IO3-和IO4-的检定步骤.本法检出的灵敏度虽不很高,但选择性较好,适于作IO3-或IO4-的检定.

Plasmochin in the presence of 1 N perchloric acid and under heating in boiling water bath reacts with iodate and periodate ions to give a red-violet coloration which is insoluble in ordinary organic solvents(19 organic solvents have been tested).The optimum conditions and selectivity of the colour reaction have been investigated in detail.The identification and concentration limits in centrifuge tube have been found experimentally.
