Application

There is a large growth in copper industry in the recent years. Compares to other metals, copper has a high conductivity, malleability, and relatively low price. It is now plays a major role in semi-conductor industry. However, ionized copper in water is biologically hazardous. The presence of copper dissolved in water usually gives out a transparent blue colored solution. However, a few ppm of copper can cause death to most living things. Such trace amount of copper cannot be distinguished by naked eyes. Chemmit W3129 Copper Analyzer is designed for industries, especially the semi-conductor industry, which produces enormous amount of copper in effluent water. This analyzer uses cuprizone method to determine the concentration of copper in the solution. It offers a fast, cheap and clean analysis, with fully automatic calibration and user adjustable reaction time and analysis cycle. This Analyzer is self-monitoring, ensuring the wastewater follows the EPA standard all the time.

Application Principle

ChemMIT W3219 Copper Analyzer uses cuprizone method to detect the presence of copper ions in the solution. A simplified chemical equation to illustrate the reaction is:
Cu + Cuprizone → Cu － Cuprizone complex

In general, copper ions react with cuprizone, producing a blue color complex. By measuring the absorption at the wavelength around 595~600nm, the concentrations yields a continuous line, which can then be used to determine the concentration of copper ions. The reaction is normally fast under ambient temperature, but a buffer must be used to maintain the pH around 7.5~9.5 to avoid interferences. The sample and reagents are delivered through automatic pumps, providing thorough mixing and precise reagents ratio per reaction. After a user programmed reaction time, the resultant product is sent to the photometer for detection.
