Description
The addition must be made slowly and under stirring. Consult your technical consultant beforehand who will define the safety protocol to be followed during the preparation of this mixture. This method must not be used in a confined space, and a vent to the atmosphere is necessary to evacuate the oxygen as it forms.
CORROSION: DEPTIL POH is minimally corrosive to stainless steels; in aqueous solutions, DEPTIL POH does not cause pitting or crevice corrosion to the stainless steels commonly used in the food industry.
Control parameters: Sample dose: 5ml Pretreatment: 0.1 N Sodium thiosulfate Indicator: KI Reagent: 20% H2SO4 Titrant factor: f = 0.05±0.01 Concentration in % = titrant ml * f Concentration in g/l = titrant ml * f * 10
