| This paper analyzed the reagent formula for the HACH ammonia monitor, including oxidant, chromogenic reagent, catalyst, masking agent, component of buffer solution, dosage of agents, reaction mechanism, absorption spectrum, pH value, coloring time and coloring temperature, stability of coloration product, the sensitivity, interference and storage conditions. According to this study, a domestic reagent formula was developed. This reagent formula had no significant difference with the imported reagent through comparison test. |
