## Abstract Following a review of previous work Vaughn's method is selected for modification and incorporation in a composite scheme of analysis. Colour stability curves show that stannous chloride is superior to other reducing agents and indicate the optimum acid concentration for reproducibility.
A simple and sensitive spectrophotometric method for the determination of molybdenum(W) in sea water samples was developed. It is based on the extraction of the M~VI)-phenylfluorone complex on a membrane filter by simple ~ltration and direct measurement of the absorbance on the fiiter. The extractio
