Ni Online Analyzer/ Ni Online Meter, Water Analyzer, Sewage Water Treatment, Waste Water Treatment
Ni is a kind of silver white, hard and brittle metal. It is stable at room temperature in the air. Ni is not active element. Ni reacts with HNO3 easily, but with HCl and H2SO4 slowly. Ni exits in various ores, often combines with S, As and Sb. mainly coming from the chalcopyrite, the nickel chalcopyrite and so on. Ni may be found in the wastewater from mining, smelting, alloy production, metal processing, electroplating, chemical and production of the ceramics and glass.
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.
This product uses Spectrophotometric method. After mixing the water and the buffer, Ni converts t converts to high valence ions in the presence of strong oxidizer. Then, the high ions and the indicator react to a colored complex, in the presence of the buffer solution and the indicator. The analyzer detect the change of color, convert and output the Ni value. The amount of the generated colored complex is equivalent to the amount of Ni.
This product is a single factor test and analysis instrument.
This method is suitable for the waste water, containing of Ni within 0~30mg/L.
