The determination of total organic matter (carbon content) in aqueous media. Part III. Organic carbon in trade wastes and sewage effluent

Abstract

The method described previously has been adapted for the determination of organic carbon in industrial trade wastes, sewage effluent and river water. By using commercially available equipment and purified gas supplies, the sensitivity has been improved 10-fold, and the apparatus blank has been reduced to less than one fifth. Samples containing as little as 1 p.p.m. of carbon can now be tested by direct injection into the apparatus.
