Application

For drinking water purification: no residual chlorine odor, treatment of sewage with sterilization, removal of phenol, deodorization.

Textile industry: As a textile bleaching agent, sodium chlorite reacts with many fibres. It can be utilised on cotton as well as on vegetable and synthetic fibres such as nylon, perlon, rhovyl, and dralon.

Paper industry: Its oxidising action causes the destruction of pectins in the cellulose fibres, making them more soluble and pliable. It is also utilised to remove colour without attacking the fibres themselves.

It is also used to produce chlorine dioxide in the laboratory; In the scrubbers, because it is a very strong oxidant; To wash fruits and vegetables, and as an anti-mould because of its fungicide action.
