What are the ammonia nitrogen test methods

Ammonia nitrogen refers to the nitrogen in ammonia or ammonium state in water, which is one of the important indicators of eutrophication and pollution of water bodies. There are many methods for the determination of ammonia nitrogen, and this article will introduce five commonly used methods, namely Nessler’s reagent spectrophotometry, salicylic acid-hypochlorite spectrophotometry, distillation-neutralization titration, …

What are the residual chlorine test methods? What are the pros and cons of each?

According to the “Hygienic Standard for Drinking Water” (GB5749-2006), the residual chlorine content of the factory water is ≥ 0.3mg/L, and the residual chlorine concentration of the water at the end of the pipe network is ≥0.05mg/L, which is not harmful to the human body. Although the residual chlorine of the latter still has the …
