摘要：The basic principle of determining ammonia nitrogen by nessler’s reagent colorimetry was expatiated, and the preparation method of nessler’s reagent, blank control, curve drawing method, water sample treatment technology (preservation time, dilution method, absorption liquid type, outflow liquid volume), accuracy control, precision control and other influences on the determination results were discussed. The solutions are proposed according to the practical analysis and practice. It provides reference for analysis workers to carry out ammonia nitrogen detection in water.
