visocolor ECO Copper Test Kit
Test kit for performing colorimetric tests on copper ions in surface water and
sewage
Method:
Combined with cuprizone [oxalic acid bis(cyclohexylidene hydrazide)], copper
(II) ions form a blue complex in the alkaline range.
Measurement range
0.1–1.5 mg/L Cu2+
*Contents (refill pack):*
sufficient for 100 tests
30 mL Cu-1
20 mL Cu-2
2 screw-plug measuring glasses
1 slide comparator
1 color chart
1 plastic syringe 5 mL
1 instruction for use
Hazard warning
Information regarding safety can be found on the box’ label and in the safety data sheet. You can download the SDS from www.mn-net.com/SDS.
Instructions for use
also refer to the pictogram on the back of the color chart
-
Pour a 5 mL water sample into each of the measuring glasses using the plastic syringe. Place a measuring glass on position A in the comparator.
Only add the reagent to measuring glass B. -
Add 5 drops of Cu-1, seal the glass and mix.
-
Add 5 drops of Cu-2, seal the glass and mix.
-
Open the glass after 10 min and place it on position B in the comparator.
-
Slide the comparator until the colors match in the inspection hole on top. Check the measurement reading in the recess on the comparator reed. Mid-values can be estimated.
-
After use, rinse out both measuring glasses thoroughly and seal them.
The reagents can be used for the photometric evaluation with photometers PF-12
/ PF-12 Plus / Advance.
This technique can be used also for analyzing sea water.
Disposing of the samples
Information regarding disposal can be found in the safety data sheet. You can download the SDS from www.mn-net.com/SDS.
Interferences
Strongly acidic and buffered test samples are to be adjusted to pH 9 with
ammonia before determination.
Iron(II), chromium(VI), nickel and manganese ions disrupt tests if they are
present in concentrations in excess of 10 mg/L. Chromium(III) ions present in
concentrations in excess of 10 mg/L cause clouding and lead to limited
results. Cobalt ions form a red color complex and, depending on the
concentration of copper, disrupt the tests if present in concentrations from
as little as 1 mg/L. If cyanide and sulfide are present in concentrations in
excess of 1 mg/L, they will lead to limited results.
Conversion table:
| mg/L Cu2+ | mmol/m3 |
|---|---|
| 0.1 | 1.6 |
| 0.2 | 3.1 |
| 0.3 | 4.7 |
| 0.5 | 7.9 |
| 0.7 | 11.9 |
| 1 | 16.9 |
| 1.5 | 24.9 |
Storage
Store the test kit in a cool (< 25 °C) and dry place.
