Cheema, M. N. published the artcileSynergic effect of triphenylphosphine oxide (TPPO) on the extraction of Hg(II), Se(IV), Co(II) and Mn(II) with fluorinated pyrazolone (HPMTFP)<\/i><\/b>, Recommanded Product: 5-Methyl-2-phenyl-4-(2,2,2-trifluoroacetyl)-1H-pyrazol-3(2H)-one<\/a>, the main research area is metal extraction triphenylphosphine oxide HPMTFP; cobalt extraction triphenylphosphine oxide HPMTFP; mercury extraction triphenylphosphine oxide HPMTFP; manganese extraction triphenylphosphine oxide HPMTFP; selenium extraction triphenylphosphine oxide HPMTFP.<\/p>\n

Extraction of Hg(II) Se(IV), Mn(II) and Co(II) has been carried out with 1-phenyl-3-methyl-4-trifluoroacetyl-2-pyrazolin-5-one (HPMTFP) and triphenylphosphine oxide (TPPO) in chloroform at pH 1-10. Quant. extraction of Hg(II), Mn(II) and Co(II) at pH 4 with equimolar 0.05 M (PMTFP + TPPO) in chloroform was observed Se(IV) remains unextracted at this pH range. The stoichiometric composition of the extracted complexes M(PMTFP)2\u00b7nH2O (M = Mn, Hg), M(PMTFP)2\u00b72TPPO (M = Mn and Co) and Co(PMTFP)2\u00b7TPPO \u00b7 H2O at less than 0.1M TPPO has been established. The formation constants Km,0 and Km,n and stability constants \u03b2m,n have been computed. The anal. method developed was applied to the IAEA standard reference material potato fluor V-4 for the determination of these elements using neutron activation technique.<\/p>\n

Journal of Radioanalytical and Nuclear Chemistry published new progress about metal extraction triphenylphosphine oxide HPMTFP; cobalt extraction triphenylphosphine oxide HPMTFP; mercury extraction triphenylphosphine oxide HPMTFP; manganese extraction triphenylphosphine oxide HPMTFP; selenium extraction triphenylphosphine oxide HPMTFP. 1691-93-6 belongs to class pyrazoles-derivatives, name is 5-Methyl-2-phenyl-4-(2,2,2-trifluoroacetyl)-1H-pyrazol-3(2H)-one, and the molecular formula is C12H9F3N2O2, Recommanded Product: 5-Methyl-2-phenyl-4-(2,2,2-trifluoroacetyl)-1H-pyrazol-3(2H)-one<\/a>.<\/p>\n
