A rapid spectrophotometric method for the determination of molybdenum(VI) in seawater based on extraction and back extraction is described. Molybdenurn(VI) is extracted as the thiocyanato complex from 400 cm^3 of a seawater sample into 30 cm^3 of 1 × l0^<-2> mol dm^<-3> capriquat (trioctylmethylammonium chloride) benzene solution and then back-extracted into 3 cm^3 of 4 mol dm^<-3> nitric acid-1 mol dm^<-3> trichloroacetic acid solution, followed by spectrophotometric determination of molybdenum(VI) as molybdenum(V) thiocyanato complex after reduction. The concentration of dissolved molybdenum(VI) in Ibaraki coast(seashore of The Pacific Ocean) seawater was found to be 11.3 μg dm^<-3> with a relative standard deviation of 2.1%. Other cations in seawater were found not to cause interference.
