The application of negative absorption spectrophotometry in discolouring kinetic spectrophotometry has been studied with fishing discolouring kinetic spectrophotometry determination of SO 2- 3 as an example. Compared with positive absorption spectrophotometry, the proposed method can increase sensitivity by 40%, lower the standard deviation by 83.4% and extend the linear dynamic range by two orders of magnitude.
