Application des Capteurs Automatises DTO,COT et DCO au Dosage des Hydrocarbures dans L'Eau

Abstract

Among the objectives of this study was the determination of the oxidation yields for pure hydrocarbons in water (alkanes, alkenes, aromatics), following the TOD, TOC and COD methods, and the extraction efficiency of carbon tetrachloride followed by infra-red dosage (NFT90203).

For the global oxidative pollution tests, the best oxidation yields were obtained with TOC, followed by the TOD; COD results were clearly poor. The solvent extraction procedure afforded reliable results.

Correlation studies with the methods proposed enable the grouping of hydrocarbons in two main categories, according to the oxidation criteria: aliphatics and aromatics. Generally, it can be said that the correlations found were satisfactory.
