Rapid-micro-determination of iodine in water
- 1. Commissariat a l'Energie Atomique, Pierrelatte (France). Section protection
Description
A method is described for detecting one microgram of iodine per litre of water. After having tested manually volumetric and colorimetric methods, the authors chose a kinetic method. Reduction of arsenious oxide by ceric sulphate is catalyzed by the presence of small quantities of iodine. Failure of manual tests led to the adoption of a Technicon auto-analyzer for carrying out the determination; this improves the reproducibility of the method and gives a sensitivity of about 1 microgram of iodine per litre with an accuracy of ±15 per cent.

Apres des essais manuels infructueux ce dosage est effectue au moyen d'un auto-analyseur Technicon, ce qui ameliore la reproductibilite de la methode et permet d'obtenir une sensibilite de l'ordre du microgramme par litre en iodure a ±15 pour cent pres.
