Test Kit For Water-62

COD Test Kit for Sewage.

The determination of sulfite usually is made only on boiler waters or on waters that have been treated with catalyzed sodium sulfite for corrosion prevention.

Standard potassium iodide-iodate titrant standardized to 0.0125N . Titrate with potassium iodide-iodate titrant until end point and faint permanent blue color develops.

Glycerol sulfate solution is used to maintain proper crystal size in pricipitation of SUFATE, during SULFATE TEST. As The resultant turbidity of solution is measured at a wave length sensitive to turbidity on a photometer.

Glycerol sulfate solution is used to maintain proper crystal size in pricipitation of SUFATE, during SULFATE TEST. As The resultant turbidity of solution is measured at a wave length sensitive to turbidity on a photometer.

This method is based on the precipitation of sulfate ion in such a manner as to form compound sulfate crystals of uniform size.
