How to use?
Nickel Test specification
1. Fill a clean test tube with sample to the 15-mL mark.
2. Add 1 mL Nickel () Reagent to the tube and swirl to mix.
3. Add 1 mL Nickel () Reagent to the tube and and swirl to mix, stand for 15 minutes.
4. Add the contents of one Nickel () Reagent to the tube, cap and shake to dissolve.
5. Place the tube in 1 cm above the blank of standard card, compare the color from top to bottom, the standard color level has the
same color as obeserved from the tube shows the concentration of nickel in the sample.
Notes
1. The sample pH: 4.0-7.0, temperature: 20-35.
2. In sample, the concentration of Cu2+and Co2+ reaches 5 times to that of Ni+ , or the concentration of Zn2+,Pb2+,Al2+,Fe3+,Mn2+ reaches 20 times to that of Ni+, will interfere with the test.3. In step 2 and 3, swirl slowly to avoid forming foam.
