Determination of Copper concentration in process water

The concentration of copper (0.2-2 mg/L) in galvanic waters indicates that the wastewater is not suitable for direct discharge into surface waters or sewers and requires treatment. For recycling, values <0.2 mg/L are ideal, while 0.2-2 mg/L require intermediate treatment for reuse in washing or processes, reducing costs and environmental impact.

Method

Test type: End Point.

Testing time: 6 minutes.

Analysis sessions with multiple samples are possible up to a maximum of 16 tests for CDR GalvanLab® and 3 tests for CDR GalvanLab® Junior.

Passo 1
Step 1/12
Collect 1000 µL of sample with the proper pipette and pour it into an empty cuvette. Close it with the supplied cap.
Passo 2
Step 2/12
Collect 20 µL of R1a with the pipette.
Passo 3
Step 3/12
Add 20 µL of R1a to the cuvette without touching the tip in the sample. In case of contamination, replace the tip.
Passo 4
Step 4/12
Gently shake the cuvette 2-3 times.
Passo 5
Step 5/12
Place the cuvette in one of the incubation cells and start the timer by pressing the timer icon.
Passo 6
Step 6/12
Gently shake the cuvette 2-3 times.
Passo 7
Step 7/12
Select the cuvette to be read from the display. Place the cuvette in the cell marked with the blue light and press READ.
Passo 8
Step 8/12
Collect 20 µL of R2 with the pipette.
Passo 9
Step 9/12
Add 20 µL of R2 to the cuvette without touching the tip in the sample. In case of contamination, replace the tip.
Passo 10
Step 10/12
Place the cuvette in one of the incubation cells and start the timer by pressing the timer icon.
Passo 11
Step 11/12
Gently shake the cuvette 2-3 times.
Passo 12
Step 12/12
Place the cuvette in the cell marked with the blue light and press READ to perform the photometric reading.

Sample treatment

The sample can be used as is.

Principle of the test

The copper content is determined by its reaction with a chromogen which develops a colour change, whose optical intensity measured at 620 nm, is proportional to the copper concentration in the sample analyzed.

Calibration curve

Calibration curve was obtained by correlating the CDR method with the reference method.
