A Method for Eliminating Sulfide Interference in the Determination of Ammonia Nitrogen in Sewage by Nesser's Reagent Spectrophotometry
In order to effectively solve the interference problem caused by sulfide in the determination of ammonia nitrogen content,the corre-sponding elimination strategy is put forward.The experimental results show that pretreatment of water samples containing sulfide with hydrogen peroxide can significantly improve the accuracy and precision of determination of ammonia nitrogen in synthetic ammonia production wastewater.
