title: A non-extractive sequential injection method for determination of molybdenum.
abstract: A non-extractive sequential injection spectrophotometric method for the determination of molybdenum has been developed. The method is based on the reaction between the thiocyanate complex of molybdenum and the polymethine dye (2-[2-(4-dipropylamino-phenyl)-vinyl]-1,3,3-trimethyl-3H-indolium chloride) in a hydrochloric acid medium. The calibration plot in the SIA system was linear from 0.080mgL(-1) to 1.92mgL(-1) of Mo; LOD was 0.021mgL(-1). The method was applied for the determination of molybdenum in spiked drinking water and mineral water.
