A hydrosulfite solution is prepared from 5.00 g sodium hydrosulfite, 2.00 g sodium hydroxide, and 93.00 g DI water. 1.00 g of dry product is dissolved in 999.0 g STW water and 1 ml samples are taken at 1, 2, 5, and 10 minutes. 1 ml sample is added to 98.0 g STW water and mixed. Then 1 ml hydrosulfite solution is added and mixed. Absorbance is read at 394 nm using a Pye Unicam Spectrophotometer SP1750. Absorbance of the test sample is matched with absorbance on control graph to give % Paraquat dichloride.
