Provisions prepared.
5 Method summary
Sample of chlorate in an acidic medium, is reduced to ferrous sulfate, chloride, determination of total chlorine ion with silver nitrate turbidimetry, chlorine
Subtracting the total amount of chloride ion in the presence of chlorine patterns, which is the difference in terms of the content of chlorate.
6 Reagents
6.1 the nitric acid solution. 1 + 2.
6.2 Silver nitrate solution. 17g/L.
Glycerol solution was 6.3. 1 + 4.
6.4 ferrous sulfate solution. 100g/L.
Weigh 10g of ferrous sulfate (FeSO4 · 7H2O) was dissolved in an appropriate amount of water, plus 10mL of concentrated sulfuric acid, ImL silver nitrate solution, diluted with water
To 100mL, shake, filtration. The solution is using now.
Chloride 6.5 Standard solution. 1mL solution containing chlorine (Cl) 0.010mg.
Pipette Pipette 1mL chloride standard solution according to HG/T 3696.2 prepared, placed in 100mL volumetric flask, dilute with water to
Mark and shake. The solution is using now.
