摘要：
In recent years, precious metals production through hydrometallurgical process has been attended; however the Low grade of metals is one of the main problems. Thus, solvent extraction method was purposed for concentration and purification of aqueous solution. In this study, Tri butyl phosphate (TBP) was used to PdCl3 low concentrations of TBP could extract Pd chloride ions. The Solution containing 180 mg/l Pd was extracted by 0.05-0.25 M TBP in different HCl concentration. Increasing HCl concentration decreases Pd extraction percentage. It seems that different chloride complexes formations cause the extraction percentage to change in various HCl concentrations. The extracted macromolecule is determined PdCl3-center dot TBP center dot xHR(2)O center dot HNO3 and NaCl has negative effect on Pd extraction.
