WebIn this work, a polyethylene glycol (PEG)/Na 2 SO 4 aqueous two phase system (ATPS) was formulated for the extraction of phosphoric acid from an aqueous solution to a polymer rich phase. The optimal conditions to form a biphasic system in the presence of phosphoric acid were determined experimentally. The phase diagram of ATPS composed of water, PEG, … Webthe process. Phosphoric Acid Phosphoric acid (H 3PO 4) is primarily used in the manufacture of phosphate salts ( e.g. for fertilizers and animal feed supplements). Two different pro cesses can be used in the manufacture of phosphoric acid. In the first process, known as the thermal process, elemental phosphorous is produced from WebDec 1, 2015 · The purified phosphoric acid is compared with thermal acid and results show a reduction in all impact categories when using wet process instead of thermal one, excepted for (i) eutrophication. ...
