Do có nồng độ cao trong phần lớn các loại nước thải nên chloride thông thường là nguồn quan trọng nhất trong việc gây nhiễu. Phản ứng của nó với dicromat kali như sau:
Nền tảng cho thử nghiệm COD là gần như mọi hợp chất hữu cơ đều có thể bị oxy hóa đầy đủ để tạo ra dioxide cacbon bằng các chất oxy hóa mạnh trong các điều kiện axít.
1 vial is marked for a “blank,” and 3 or four vials are marked with regarded conventional ranges. Two vials are then marked for that wastewater sample to make a duplicate run. Notice: If more info many wastewater samples are being run, a minimum of 10% of samples are duplicated.
The future of COD measurement lies in the event of safer, extra precise, and even more successful methods. As our understanding of the nature and conduct of organic COD testing and natural compounds in h2o increases, so too will our power to measure and Manage their effect on the ecosystem.
Considerable observation of the COD and BOD ranges on the exact same wastewater has proven that the COD to BOD ratio of a specific wastewater will continue to be continuous after some time.
Wastewater Remedy Performance: COD measurements are essential for assessing the performance and performance of wastewater treatment procedures.
