Chromium (Chromium Six )
Test Specification
1. Chromium (Six) test in water sample
| a) Fill a clean test tube with water sample to the 15-mL mark. Add the contents of one Chromium Reagent, cap the tube and shake to dissolve, stand for 15 minutes. |
| b) Open the cap, 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 observed from the tube shows the concentration of Chromium in the water sample. |
2. Chromium test in solid sample
|
a) The Chromium in a certain amount of solid sample are transferred to the water phase by the boiling at first. |
| b) Then, the content of Chromium in water phase can be detected according to the method 1. |
| c) At last, the concentration of Chromium in the solid sample can be calculated . |

Q2: When doing chlorine (or ozone, total chlorine) testing of for water samples,the longer time, the deeper the color, and why?
A2: Because the containing DPD reagent may react with the air oxidation, it is proposed in strict accordance with the test instructions, to control the reaction time.
Q3: Why the water sample shows pink after adding DPD chlorine (or total chlorine, ozone) reagent ,and then faded to become colorless?
A3: The reason may be that the concentration of chlorine (total chlorine, ozone) in the water is too high, dilution is recommended before testing.
