A new simple, sensitive and economical spectrophotometric method is proposed for the determination of trace amount of hydroxylamine at microgram level in water effluent of paper recycling industry. Hydroxylamine has been determined by its oxidation to nitrite by using known excess of potassium iodate. KIO3 in acidic medium bleaches the methyl red dye. A known excess of potassium iodate was reduced when treated with hydroxylamine and methyl red is used for the determination of unreacted potassium iodate. The absorbance of the methyl red dye after the reaction was monitored spectrophotometrically at 520 nm. Beer’s law was obeyed over the concentration range of 1-10 μg of hydroxylamine in an overall aqueous volume of 20 ml with a correlation coefficient of 0.999. The proposed method was successfully applied for the detection of Hydroxylamine in water effluent of paper Recycling industry.
