<\/a>Principe et utilisation d'un analyseur de ph\u00e9nols volatils<\/h2>\n

Le ph\u00e9nol volatil est une substance hautement toxique ; l'ingestion d'une certaine quantit\u00e9 par l'homme entra\u00eene l'apparition de sympt\u00f4mes d'intoxication aigu\u00eb ; la consommation \u00e0 long terme d'eau contamin\u00e9e par du ph\u00e9nol peut provoquer des maux de t\u00eate, des \u00e9ruptions cutan\u00e9es, des d\u00e9mangeaisons, de l'an\u00e9mie et divers sympt\u00f4mes neurologiques. Lorsque la teneur en ph\u00e9nol de l'eau \u00e9tait comprise entre 0,1 et 0,2 mg\/l, la chair des poissons pr\u00e9sentait une odeur particuli\u00e8re, et lorsque cette teneur d\u00e9passait 5 mg\/l, les poissons mouraient d'empoisonnement.<\/p>\n

Principe : en milieu alcalin, en pr\u00e9sence de ferricyanure de potassium, les compos\u00e9s ph\u00e9noliques pr\u00e9sents dans l'eau r\u00e9agissent avec la 4-aminoantipyrine pour former des compos\u00e9s de couleur rouge-orange, dont l'absorbance est proportionnelle \u00e0 la teneur en ph\u00e9nol volatil de l'eau ; la teneur en ph\u00e9nol volatil de l'eau a \u00e9t\u00e9 calcul\u00e9e en mesurant l'absorbance de ce compos\u00e9.<\/p>\n

Il convient \u00e0 l'analyse en laboratoire ou \u00e0 l'analyse, dans le cadre de processus de production industriels, de l'eau, des eaux us\u00e9es, des eaux us\u00e9es urbaines, des cours d'eau, des lacs, de la mer et d'autres eaux de surface.<\/p>","protected":false},"excerpt":{"rendered":"
