Abstract: The extraction mechanism of molybdenum from sulfate system by trialkyl benzyl ammonium sulfate (TABAS) has been studied.The results showed that the extraction rate of molybdenum has a maximum value at pH=2—3.The composition of the extracted complex is [R3NCH2-C6H5]3HMo7O23 as determined by the saturation method and slope method.

Key words: Mechanism of extraction, Molybdenum, TrialkyI benzyl ammonium sulfate
