College, Kopargaon-423 601 Manuscript received 3 March 1987, revised 6 April 1988, accepted 6 July 1988 An aluminium- copper alloy has been used as a reductant in the determination of molybdenum(VI) and tungsten(VI). The process requires 15-20 min and reduction to the lower state is quantitative. The proposed procedure can be used for routine estimations. Alloys containing, 8 and 4% Cu are suitable for reduction of MoVI and Wvi respectively. Effect of acid strength of the medium and nature of the reduction process are discussed. Mo in ferromolybdenum alloys and W in ferrotungsten alloys can be determined. Interference of commonly occurring, ions has been studied. The proposed method has significant advantages over the method using, Jone's reductor filled with amalgamated zinc granules.
