摘 要:
The extraction rate is the key factor affecting the production efficiency and cost in purification of wet-process phosphoric acid by solvent extraction process. The effects of extraction temperature, concentration of raw material acid, impurity content in raw material acid, phase ratio on extraction rate are studied. The results show that: every factor has great influence on extraction rate; The optimum conditions are w(P_2O_5)in raw material acid of 55%-57%,extraction temperature of 40-45 ℃,phase ratio of 4.0.
