In chemical oxygen demand (COD) determination, according to the standard methods, K2Cr2O7 is used as an oxidant and Hg is used in order to inhibit interference of Cl-. K2Cr2O7 and Hg are characterized as toxic substances. In this study, Na2S2O8 and Mn(III) were used as oxidants and in order to inhib...
