This chapter focuses on various methods of analyzing organic compounds in water, particularly through Chemical Oxygen Demand (COD) and Total Organic Carbon (TOC) tests. It discusses the procedures involved in these methods as well as their significance for understanding water quality and pollution. The limitations and interferences associated with these tests are also highlighted, along with the importance of calibration and the validation of results in wastewater analysis.

This chapter focuses on various methods of analyzing organic compounds in water, particularly through Chemical Oxygen Demand (COD) and Total Organic Carbon (TOC) tests. It discusses the procedures involved in these methods as well as their significance for understanding water quality and pollution. The limitations and interferences associated with these tests are also highlighted, along with the importance of calibration and the validation of results in wastewater analysis.
Chemical Oxygen Demand (COD) is a rapid method to measure organic load but can be affected by interferences.
Total Organic Carbon (TOC) directly measures organic carbon levels in water and is more specific than COD or BOD.
Understanding the limitations and methodologies associated with these tests is crucial for accurate water quality assessment.
A metric used to measure the amount of organic compounds in water by assessing the amount of oxygen required to oxidize these compounds.
A measure of the total amount of carbon in organic compounds present in water, giving more precise information about organic load than surrogate methods.
The amount of oxygen that microorganisms will consume while decomposing organic matter under aerobic conditions.
The process of adjusting and validating an instrument's output by comparing against a known standard.
