Copper is an essential trace element for 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 the copper reagent (BCA) colorimetric spectrophotometry method, this product has been launchedHigh range copper reagent for water quality testing.

High range copper reagent for water quality testing(BCA) spectrophotometric method: Copper ions in water are reduced to monovalent copper ions by ascorbic acid, and react with copper reagent (BCA) to produce a purple red complex. The color depth is proportional to the copper ion content in water.

Precautions for using reagents

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 pH value of the water sample to be tested should be between 4.0 and 7.0. If it is not within this range, dilute acid or dilute alkali should be used for adjustment;

4. The triangular positioning mark on the colorimetric tube should be aligned with the positioning mark on the instrument during zeroing and reading;

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.
