본문보도료HClO4체계중,2-갑안기-5-록이분갑동（R）췌취Pd적궤리,고찰료ClO-4농도、Pd2＋농도화pH대Pd췌취솔적영향,학정료췌합물조성위：[Pd·R2]（ClO4）2。
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 is[Pd·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）.
