Synergistic Extraction of Pr(Ⅲ) by 1,9-Bis(1'-phenyl-3'-methyl-5'-oxopyrazole-4'-yl)-1,9-nonanedione with Neutral Nitrogenous Extractants
Abstract:
The synergistic extractions of Pr(Ⅲ) with 1,9-bis(1'-phenyl-3'-methyl-5'-oxopyrazole-4'-yl)-1,9-nonanedione(H2A) and neutral nitrogenous bidentate extractants(B), such as 1,10-phenanthroline(Phen), 2,9-dimethyl-4,7-diphenyl-phenanthroline(DDPhen), 5-nitro-phenanthroline(NPhen), 2,2'-bipyridyl(2,2'-bipy) and 4,4'-bipyridyl(4,4'-bipy), have been investigated. The extraction complex was shown to be PrA·HA·B. The extraction constants were determined. The solid extracted species PrHA·NPhen was obtained and confirmed by elemental analysis, IR, UV, TG and DTA.
