Put together the reagent blank by taking away the COD vial cap and pipetting deionized h2o rather then sample in to the vial.
One of the most skipped phase by consumers during the COD Examination may be the reagent vial inversion action. After the digestion and prior to the vial is thoroughly cooled, the vial have to be inverted numerous times.
Chemical oxygen demand (COD) is really an indirect measurement of the quantity of organic make a difference within a sample. With testing COD, you can measure nearly all natural and organic compounds that could be digested by a digestion reagent.
Desk one exhibits The standard concentrations (mg/L) of organics located in untreated domestic wastewater. This table may be used to know how non-sanitary process wastewater compares to standard domestic wastewater.
