[0003] Sodium hypochlorite is mainly used in bleaching, industrial wastewater treatment, papermaking, textiles, pharmaceuticals, fine chemicals, sanitation and disinfection and many other fields. There are many ratios for preparing sodium hypochlorite water, depending on the effective chlorine concentration and purpose of the year. But no matter which ratio is prepared, it is necessary to add Gute's sodium hypochlorite into the water and stir it before the sodium hypochlorite can be prepared.
