Copper is a trace element in the human body, but when the copper content in water reaches 0.01mg/L, it has a significant inhibitory effect on the self purification of water and is highly toxic to aquatic organisms. Copper emissions are mainly from industries such as electroplating, smelting, hardware processing, and petrochemicals. To control the pollution of water environment caused by industrial drainage, it is necessary to monitor copper ions in water. To eliminate the tedious operation of preparing reagents and testing processes for users, and improve detection efficiency, based on porphyrin indicator spectrophotometry, this product has been launchedCopper reagent for low range water quality testing.

Copper reagent for low range water quality testingThe porphyrin method is highly sensitive to trace amounts of free copper ions. This method has minimal interference and does not require extraction or concentration of the sample before analysis. Copper masking agent eliminates the interference of other metal ions on the test. Under the action of porphyrin indicator, any free copper ion in the sample will form a deep yellow complex. The test results were read under visible light with a wavelength of 425 nm.

measuring range

matters needing attention

1. For more accurate testing, the blank value of each new batch of reagents should be measured. The determination of reagent blank is also carried out according to the testing steps, except that the sample is replaced with pure water for testing. Subtract the blank value of the reagent from the final test result;

2. If the content is higher than the reagent range, the measured value can only be used to estimate the dilution factor and cannot be used as a test result. After diluting the sample, retest;

3. The water sample to be tested is colored or turbid, and the presence of a large amount of oxidants will interfere with the measurement;

4. Coexisting Al³⁺、 Fe²⁺、 Cd²⁺、 Hg²⁺、 Zn²⁺、 Pb²⁺Will interfere with the measurement;

5. Store in a dry, cool, and out of reach of children. Do not store together with food, medicine, etc., and do not put into fire.
