Ảnh hưởng của nồng độ ion clorua lên việc xác định chỉ tiêu độ oxi hóa trong nước

The primary interference in oxidizability measurement is the present of chloride ion in water because of its oxidation ability in acidic medium. To avoid the positive interference of chloride on the oxidizability value, the determination could be carried out under alkaline condition. Investigation of the chloride concentration on the oxidizability under acidic and alkaline conditions was presented.
