硫化氢在磷酸溶液中溶解度的实验研究

Abstract

Abstract: In order to determine the optimum dosage of P2S5 and technological conditions in purification process of phosphoric acid by using excessive amount P2S5 as generating agent，the solubility data of H2S in phosphoric acid was measured by single gas circle method in different temperatures and H2S partial pressures under atmospheric pressure. Results showed that the solubility of H2S decreased with increasing temperature and concentration of phosphoric acid，but increased with increasing the partial pressure of H2S.The data had linear relationship and agreed with normal gas solubility rule.Solubility data were related and calculated by using I.H.Cho model and the significance level of correlation reached 0.01.The average deviation between experimental and calculated values was 1.60%.The results have a guiding significance for the purification technology of phosphoric acid.

Key words: H2S, phosphoric acid solution, phosphoric acid purification, solubility
