How to improve the quality of sodium hypochlorite with low effective chlorine content
Thread Content
The alkali solution has a concentration of 5%, with an effective chlorine content of only 3%. Can adding more chlorine increase the effective chlorine content?
Continuing to pass chlorine gas can further increase the effective chlorine content. Generally, for sodium hypochlorite, the alkali solution concentration needs to be above 14%, the resulting effective chlorine level is around 10%, and the alkali content is less than 1.5%, or 25 g/l. If the container used for these hyposodium substances can hold enough volume, add about 1/7 of that volume of concentrated alkali, and then absorption will take place ； If it is no longer possible to increase the concentration of alkali, the alkali content can also be reduced to below 25 g/l.
