Pre loaded reagent for total nitrogen

Pre loaded reagent for total nitrogenProduct Introduction

The total nitrogen (TN) content in water is one of the important indicators for measuring water quality. Excessive nitrogen and phosphorus in surface water can lead to the proliferation of microorganisms, vigorous growth of planktonic organisms, and eutrophication. The determination of total nitrogen index is helpful in evaluating the pollution and self purification status of water bodies, and has important significance for environmental protection. Develop a pre made reagent for total nitrogen detection based on the nitrate chromium transformation acid detection method. In the visible light region at a wavelength of 420nm, it is less affected by various impurities and can meet the requirements of batch, rapid, and accurate determination of water quality for various environmental water, domestic sewage, and industrial wastewater.

Under alkaline conditions, after being oxidized and digested by potassium persulfate, all nitrogen-containing components in the water sample are converted to nitrate. After using Jiao Ya * to remove excess chlorine and oxidizing substances, in a strongly acidic medium, nitrate reacts with chromic acid to form a yellow complex. The depth of yellow is directly proportional to the total nitrogen content in the sample.
