- Scope
- Important note: The strong acid used in this standard is corrosive, and beryllium sulfate is a highly toxic substance, so care should be taken when using it. If splashed on body, rinse with plenty of water and avoid inhalation or skin contact. This standard specifies the determination method of aluminum ions in industrial circulating cooling water. The catechol violet spectrophotometric method in this standard is suitable for the determination of aluminum ion content in industrial circulating cooling water between 2 μg/L and 500 μg/L. It is also suitable for drinking water, groundwater, and lightly polluted surface water and seawater. Determination of aluminum ions in water; the test Tieling spectrophotometric method is suitable for the determination of aluminum ions in industrial circulating cooling water between 0.02 mg/L and 2.00 mg/L. It is also suitable for boiler water, desalted water, condensate water, and furnace water. , Determination of aluminum ions in cooling water of water-cooled generators, etc.
