| Abstract: | The extraction mechanism of palladium from perchloric acid medium by di 2 ethlhexyldithiophoric acid(D 2EHDTPA)?has been studied. The results show that extraction rate of palladium increase with increasing of the pH, and no relationship with concentration of perchlorate.The composition of the extraction is PdL 2 as determined by slope methed. The extraction mechanism of palladium with D 2EHDTPA based on UV vis spectra is proved to be chelate extraction reaction as 2HL (O) Pd 2 (A) =PdL 2(O) 2H (A) . |
