【 摘 要 】

This paper mainly compares the determination of ammonia in indoor air by hypobromite oxidation method and salicylic acid spectrophotometry, and selects higher precision, higher sensitivity, larger linear range and more stable results. The reproducible salicylic acid method is improved. In this way, the salicylic acid method is more convenient, time-saving and easy to operate, and is advantageous for the application of the method in a wider range.
