Total Phosphorus Online Water Quality Analyzer
Model No.:JM-2200
Phosphorus harm to marine organisms, most of the marine organisms are very sensitive to organophosphorus pesticides, some drug-resistant insects do not respond to the concentration of pesticides, and soon be able to make marine organisms die. There is an important nerve transmitting substance acetylcholinesterase in the human body, organophosphorus will inhibit cholinesterase so that it can not break down the acetylcholinesterase, resulting in the accumulation of a large number of acetylcholinesterase in the nerve centre, thus causing poisoning. Severe cases may even cause death. Long-term low-dose organophosphorus pesticides can not only cause chronic poisoning but also carcinogenic, teratogenic and other hazards to the human body.
Detailed Description
1.Product overview:
Phosphorus harm to marine organisms, most of the marine organisms are very sensitive to organophosphorus pesticides, some drug-resistant insects do not respond to the concentration of pesticides, and soon be able to make marine organisms die. There is an important nerve transmitting substance acetylcholinesterase in the human body, organophosphorus will inhibit cholinesterase so that it can not break down the acetylcholinesterase, resulting in the accumulation of a large number of acetylcholinesterase in the nerve centre, thus causing poisoning. Severe cases may even cause death. Long-term low-dose organophosphorus pesticides can not only cause chronic poisoning but also carcinogenic, teratogenic and other hazards to the human body.
2.Product Principle:
Water samples, catalyst solution and strong oxidant digestion solution mixture heated to 120 ℃, water samples of polyphosphate and other phosphorus compounds, in the high temperature and high pressure acidic conditions by a strong oxidant digestion oxidation of phosphate, in the presence of a catalyst, phosphate ions in the molybdate-containing strong acidic solution, the generation of a chromogenic complex, the analyzer detects the colour change, and this change is converted to total The analyser detects the change in colour and converts this change to a total phosphorus value. The amount of coloured complex generated is equivalent to the total phosphorus content. This product is a single factor parameter test analyser, this method is applicable to phosphorus in the range of 0-500mg / L wastewater. For the detection of wastewater containing large amounts of organic matter, the measurement results may be low.
