| Abstract: | The extraction mechanism of Palladium from perchloric acid medium by 5-chloro-2-(methylamino)benzophenone(R)is studied.The ClO-4concentration,Pd2+concentration and the pH value to influence of the extraction rate of Pd are investigated.The composition of the extraction isPd·R2](ClO4)2as determined by slope method.The extraction mechanism of Palladium with 5-chloro-2-(methylamino)benzo-phenone based on UV-spectra is proved to be chelate extraction reaction as follows:2R(O)+Pb(A)2++2ClO4-4(A)=Pd·R2](ClO4-)2(O). |
