Research experiences in microwave-assisted chemical oxygen demand determination
The conventional COD determination through reflux method, although still much in experimental practice for water and wastewater analysis, is time consuming, complex and prone to a number of errors. A simpler, more rapid, environmentally benign but still precise method would hence be more attractive and is, in point of fact, a pressing need. Contextualised within the concept of Green Chemistry, this review discusses a handful of research papers published to date on microwave-assisted COD determination and brings forward the achievable improvements in COD analysis while using this clean analytical technique.
