Add to ORKGInternational audienceThe aim of this study is to illustrate the oxidoreduction reactions for the determination of the organic pollution in water. Firstly, the chemical oxygen demand (COD) is defined and the principle of the spectrophotometric dosage is remained. Then, a saccharose solution is analysed. A titration of the excess dichromate by the iron (II) and a spectrophotometric dosage of chrome (III) are performed. The results obtained are expressed in terms of COD.Le but de ce travail est d'illustrer les réactions d'oxydoréduction à travers la détermination de la pollution organique des eaux. Après avoir défini la demande chimique en oxygène (DCO) et avoir rappelé le principe d'un dosage spectrophotométrique, une eau contenant du saccha...
