Study design
- Oxygen conditions:
- not specified
- Inoculum or test system:
- other: dichromate oxidation method
- Details on study design:
- The test item was dispersed in water and was oxidized by potassium dichromate in strong sulfuric acid medium. Silver sulphate was used as the catalyst under reflux. Mercuric sulphate was added to reduce chloride interference.
Reference substance
- Reference substance:
- other: potassium hydrogen phthalate
Results and discussion
- Preliminary study:
- The preliminary test showed that a dispersion of 11.0 mg of IN-DBC80 in 100 ml of water had a COD value of 0.58 gram of oxygen to gram of test item.
- Details on results:
- The chemical oxygen demand of IN-DBC80 was determined to be 0.58 gram of oxygen to gram of test item. The relative standard deviation was 3.17%.
BOD5 / COD results
BOD5 / COD
- Parameter:
- COD
- Value:
- 0.58 g O2/g test mat.
- Results with reference substance:
- The COD determined for the standard reference solution (potassium hydrogen phthalate) was 486 mg/L. This resulted in a 97% recovery showing that the experimental procedure was satisfactory.
Any other information on results incl. tables
The chemical oxygen demand of IN-DBC80 was determined by dichromate oxidation method according to ISO 6060:1989 (E) using a COD meter. The chemical oxygen demand of IN-DBC80 in water was determined to be 0.58 gram of oxygen to gram of test item with a relative standard deviation of 3.17%.
Applicant's summary and conclusion
- Conclusions:
- The chemical oxygen demand of IN-DBC80 was determined to be 0.58 gram of oxygen to gram of test item.
