Methods
GB
Notes:
1. This test is applicable for the determination of soluble Manganese in water and waste-
water.
2. Highly buffered water samples or extreme pH values may exceed the buffering capacity
of the reagents and requires sample pre-treatment.
If samples were acidified for storing, adjust the pH between 4 and 5 with 5 mol/l (5 N)
Sodium hydroxide before test. Do not exceed pH 5, as manganese may precipitate.
3. Interferences:
