CALDUR\u00ae Kit d’essai Nitrite – Photom\u00e9trique<\/h2>\n

A quoi sert la mesure des nitrites ?<\/h3>\n

Le nitrite (NO\u2082-) est un produit interm\u00e9diaire de la transformation biologique de l’azote et un indicateur de la contamination r\u00e9cente de l’eau. La limite de potabilit\u00e9 de l’eau est de 0,5 mg\/l de NO\u2082-<\/strong> (r\u00e8glement sur l’eau potable), et de 0,1 mg\/l \u00e0 la sortie de l’usine de production d’eau. <\/p>\n

Le nitrite est dangereux pour la sant\u00e9 car il affecte la capacit\u00e9 de transport de l’oxyg\u00e8ne dans le sang (m\u00e9th\u00e9moglobin\u00e9mie). Il constitue un risque particulier pour les nourrissons et les jeunes enfants. Dans les nouvelles canalisations, les nitrites peuvent atteindre des niveaux temporairement \u00e9lev\u00e9s en raison de l’activit\u00e9 bact\u00e9rienne. <\/p>\n

Dans l’aquariophilie, le nitrite est le param\u00e8tre d’azote le plus dangereux et doit \u00eatre contr\u00f4l\u00e9 r\u00e9guli\u00e8rement. Dans les stations d’\u00e9puration, le contr\u00f4le des nitrites sert \u00e0 surveiller la nitrification. <\/p>\n

Comment fonctionne le kit de test ?<\/h3>\n

Le CALDUR\u00ae Nitrite Test Kit – Photom\u00e9trique est bas\u00e9 sur la m\u00e9thode NED (Naphtyl\u00e9thyl\u00e8nediamine). Apr\u00e8s l’ajout d’un r\u00e9actif \u00e0 l’\u00e9chantillon d’eau, une coloration rose se d\u00e9veloppe en 5 minutes et sa concentration est d\u00e9termin\u00e9e avec pr\u00e9cision \u00e0 l’aide du photom\u00e8tre WINLAB Data Line. <\/p>\n

Avantages du kit de test CALDUR<\/h3>\n
