Maximum Removal

Solvent extraction technique was performed to optimize the conditions for maximum removal of iron (III) from the simulated bauxite hydrochloric acid leaching liquor of FeCl3+AlCl3+CaCl2+HCl. Some factors influencing the extraction, such as the extractant and concentration of Fe, Al, and Ca were investigated. The results indicated that the N235 is an effective extractant for selective extraction of iron (III) from chloride liquor. The concentration of Fe in raffinate is under 0.0165 gL-1 and the losing of Al is 0.50 % by N235.

Solvent Extraction Technique

Solvent extraction technique was applied for the extraction of β-Sitosterol from jatropha seed oil．The optimum conditions for the lab scale extraction were obtained at 30ml solvent, 0.05g magnesium power, ratio of hydrochloric acid to zinc chloride of 1/1.75 (ml/g) and tetrahydrofuran as a solvent. Under the optical conditions, the yield of β-sitosterol was up to 3.27mg/g.
