Application of aqueous two-phase systems to antibody purification: A -stage approach. ... The most promising purification was achieved using an ATPS composed of 8% (w/w) PEG 3350, 10% (w/w) phosphate at pH 6 and 15% (w/w) NaCl (Rosa et al., 2007). This ATPS composition was hence selected for the single and -stage extraction of human ...

Method for removing essentially all of the chemically bonded arsenic and antimony from copper sulfide ores. The arsenic and antimony are selectively leached out using Na2S in a basic solution. The resulting Na3AsS4 and Na3SbS4 are converted to the sulfides or to ferric arsenate and ferric antimonate for safe disposal. Sodium and sulfur values are recovered for recycling in the process.

Antimony and its compounds were known to the ancients and there is a 5,000-year old antimony vase in the Louvre in Paris. Antimony sulfide (Sb 2 S 3) is mentioned in an Egyptian papyrus of the 16 th century BC. The black form of this pigment, which occurs naturally as the mineral stibnite, was used as mascara and known as khol.

Abstract. The effect of the concentrations of HF and H 2 SO 4 and organic-to-aqueous phase ratio V o: V aq on the distribution of Sb and Nb in their extraction with tributyl phosphate has been studied. It has been determined that, under the best conditions (HF free 150 g/L, H 2 SO 4 100 g/L, and V o: V aq = 0.3 : 1), and the extraction of Sb within one step is 72%, which is followed by the ...
