【Abstract】 It is experimentally established that the available molybdenum can be leached out in 6 hours by a solution containing 0 08 mol/L H 2C 2O 4 and (NH 4) 2C 2O 4 (pH 3 3) with 0 5∶10 ratio of sample to leaching liquor. In order to eliminate interference from leaching liquor, 1400 °C for ash temperature was adopted for the determination of available Mo by furnace atomic absorption spectrometry. The method has applied to the study on speciation of Mo in soils and the results are satisfactory.更多还原
