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 H_(2)SO_(4)).The effect of the anions, Cl~(-), SO_(4)~(2-) , Br~(-) , I~(-) , SCN~(-), PO_(4)~(3-), EDTA, Oxalate, acetate and tartarate on the extraction of Mo (VI) into chloroform solutions of 4-adipoylbis (1-phenyl-3methylpyrazolone-5), H_(2)Adp and 4-sebacoylbis (1- phenyl-3-methylpyrazolone-5), H_(2)SP were studied. The results showed that the masking effect of the halides on the extraction of Mo (VI) followed the increasingly order Cl~(-)-)
