Effect of Anions, Complexing and Salting - outAgents on the Extraction of Mo (VI) from AcidMedia into Chloroform Solution of Bis(4-Acylpyrazolones)

摘要

The extraction of Mo (VI) was carried out in the presence of a synergist in the organic phase and also in the presence of the corresponding acids (HCl and H2SO4).The effect of the anions, Cl-, SO42- , Br- , I- , SCN-, PO43-, EDTA, Oxalate, acetate and tartarate on the extraction of Mo (VI) into chloroform solutions of 4-adipoylbis (1-phenyl-3methylpyrazolone-5), H2Adp and 4-sebacoylbis (1- phenyl-3-methylpyrazolone-5), H2SP were studied. The results showed that the masking effect of the halides on the extraction of Mo (VI) followed the increasingly order Cl-
