Overview
M-5010-NH4+Chlor alkali chemical total ammonium inorganic ammonium water quality online analyzer $r $n $r $n Chlor alkali process monitoring significance and control standards $r $n Core safety risk: Ammonium (NH ₄⁺) in salt water reacts with chlorine gas (Cl ₂) to generate nitrogen trichloride (NCl ∝). NCl ∝ is a highly explosive substance that can easily cause safety accidents when enriched in liquid chlorine. $r $n $r $n Key control indicators: $r $n Inorganic ammonium: ≤ 1 mg/L $r $n Total ammonium: ≤ 4 mg/L
Product Details
Specialized for chlor alkali chemical industryTotal ammonium/inorganic ammonium water quality online analyzerThe core is to focus onHigh salt, strong corrosionAccurately and stably monitoring ammonium content in saline water environment for prevention and controlExplosion of nitrogen trichloriderisk
Application background:
In the chlor alkali industry, saturated brine is a key raw material for the electrolysis of chlorine gas and caustic soda. If the saltwater contains excessive ammonium ions, explosive nitrogen trichloride (NCl3) may be generated during the electrolysis process, posing a serious threat to production safety. Therefore, the total ammonium content must be reduced to 1ppm before entering the electrolytic cell
The determination of total ammonium content is an important pre control measure to prevent safety accidents within the following safety range.
Through regular testing of free ammonium and total ammonium in saltwater, targeted control measures can be taken, such as adding sodium hypochlorite for oxidation reaction, and then removing it by air blowing. Effective chlorine in refined saltwater needs to be maintained at 5-10 mg/L to ensure ammonium removal.
The total ammonium content in refined brine is ≤ 4ppm, and the NCl3 content in liquid chlorine is ≤ 10ppm, greatly improving the safety and stability of the system.
The M-5010-NH4+free ammonium/total ammonium online analyzer produced by our company for saturated saline solution is based on the principle that the water sample is converted into ammonium sulfate after high-temperature digestion in sulfuric acid and copper sulfate solution, and then the ammonia gas is blown off by adjusting the pH value>12, absorbed by an absorbent, and measured by spectrophotometry. This method complies with relevant testing standards, and the testing is accurate and reliable!

Analysis principle
Measurement of Inorganic Ammonium Content: Inorganic ammonium in the sample is evaporated in the form of ammonia under alkaline conditions, absorbed by boric acid solution, and then colored with Nessler's reagent. The sample is then subjected to photometric measurement at a wavelength of 420nm.
Determination of total ammonium: The sample is dissolved in sulfuric acid solution, and the organic matter is heated and digested under the action of a catalyst (copper sulfate). Organic nitrogen is converted into ammonium sulfate, which is evaporated in the form of ammonia with inorganic ammonium under alkaline conditions. After absorption in boric acid solution, the sample is colored with Gardner's reagent and subjected to photometric measurement at a wavelength of 420nm.
