چکیده انگلیسی
Different technologies were tested for purification of phosphoric acid produced by the wet process. Iliminite clay was found suitable for removal of humic acids and suspended materials from crude phosphoric acid. Minimizing of ferric ions from phosphoric acid was carried out using silica, while removal of fluoride was proceeded by addition of carbonate salt. Isoamyl alcohol was used for extraction of P2O5 giving value of 78.5%. Using McCabe-Thiele diagram, the number of stages for complete extraction of P2O5 was predicted as two stages. Warm distilled water had a good efficiency for stripping of P2O5. Flow chart for sequential treatment process and extraction was constructed.
