Overview
Biochemical oxygen demand Test kits for measuring Biological Oxygen Demand in water and wastewater
Product description
Complete BOD Test Kit manufacturer and supplier. Dissolved oxygen. Biochemical oxygen demand Test kits for measuring Biological Oxygen Demand in water and wastewater for applications ranged 2 - 3000 mg/l O2.
Applications
Reagents:
Manganous sulphate solution Alkali-iodine reagent
Starch indicator
0.00025 No Sodium thiosulphate solution
Notes
Estimation of dissolved oxygen in water:
Reagents: Manganous sulphate solution Alkali-iodine reagent
Starch indicator
0.00025 No Sodium thiosulphate solution
Procedure:
. 20 mL of sample water was taken in a dry breakers.
. Adding 3 drops of Manganous sulphate solution and 2 drops of alkali iodine solution to it.
. Mix well and allow the precipitate to settle down.
. Adding 2 drops of conc. H2 SO4 and mix well till the precipitate
dissolves.
.20 drops of the above solution was taken in a dry test tube.
. Adding 1 drop of starch to the tube. A blue colour of the solution appears.
. Adding Sodium thiosulphate solution drop wise with a calibrated pipette to the tube till the blue colour disappears.
. Counting the number of drops of Sodium thiosulphate solution used.
Calculation:
Volume of water = No. of drops x Drop value of the pipette = p mL Volume of Na2 S2 O3 = No. of drops x Drop value of the pipette = q mL Dissolved oxygen (ppm) = 2 x q / p
Result: The DO of the sample is ___________mg/L or ppm.
