Physicochemical speciation of molybdenum in rain water

摘要

A combination of a sensitive catalytic determination method with filtration and ultrafiltration has been used for the physicochemical speciation of molybdenum in natural and synthetic rain water samples. The concentration (C_l) of labile molybdenum was evaluated by a direct catalytic determination. The total concentration (C_t) of molybdenum was determined after the acid decomposition of the sample To calculate the non-labile concentration (C_t-C_l).
