Instran Online Copper Ion Concentration Meter
Continuous measurement of copper ion concentration in water is possible!
Method - Colorimetric Analysis After adding the sample to the measurement cell, several reagents are added to adjust the conditions of the solution (such as pH and oxidation state). Subsequently, a blank measurement is performed to correct for the effects of temperature and turbidity. Then, the final reagent is added, which reacts with the solution to produce a color that is measured at the appropriate wavelength. The photometer used allows for highly accurate measurement results. This method is based on the reduction of copper(II) to copper(I) in acidic solutions. The neocuproine reagent specifically reacts with cuprous ions (Cu⁺). If present, iron can also be reduced to iron(II) (Fe²⁺) and may react with neocuproine. This method is specific to copper, and the cuprous-neocuproine complex has a clear and relatively strong absorbance, allowing for the measurement of low concentrations of copper at the ppb level. The influence of iron can be removed with additional reagents.
