The harm of P on marine organisms: Marine organisms are very sensitive to organic P pesticides. The pesticides of some concentration, which have no effect on some resistant insects, can kill the marine life quickly. There is an important neurotransmitter, named acetylcholinesterase, in the body. The organic P will inhibit cholinesterase to prevent the decomposition of acetylcholinesterase, causing the accumulation of acetylcholinesterase in central nervous system, causing poisoning. Severe cases may even lead to death. Long-term low dose of organic P pesticide can not only make people chronic poisoning, but also produce carcinogenic and teratogenesis to human body.
This analyzer can automatic continuous work for long-term in an unattended manner. And it is widely used in industrial pollution discharge wastewater, industrial process wastewater, industrial wastewater treatment plants, municipal wastewater treatment plants and so on. Depending on the complexity at the scene, for ensure reliable and accurate testing, can choose different pre-treatment system.
The water samples, the catalyst solution and the strong oxidizing agent digestion solution, mixed and heated to 120℃. The phosphate and other phosphorus compounds in water samples can be digested and oxidized to PO43- by the strong oxidant. In the presence of the catalyst, PO43-and the molybdate react to a colored complex in the acid solution. The analyzer detects the change of color, convert and output the Total P value. The amount of the generated colored complex is equivalent to the amount of the Total P.
This product is a single factor test and analysis instrument.
This method is suitable for the waste water, containing of Total P within 0~50mg/L.
