Notes:
1. This test is applicable for the determination of soluble Manganesein water and
wastewater.
2. Highly buffered water samplesor extreme pH valuesmay exceedthe buffering capacity
of the reagents and requires sample pre-treatment.
If sampleswere 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.
