| titleOfInvention | Method for removing iron ions from drinking-water-level polyaluminum chloride |
| abstract | The invention discloses a method for removing iron ions from drinking-water-level polyaluminum chloride. According to the method, the following ingredients in mass percentage: 20%-55% of polyhydroxy acid, 15%-45% of organic ketone and 15%-65% of heterocyclic oxides, are adopted to produce a compound agent by compounding; the compound agent is added into the polyaluminum chloride according to a mass percentage ratio of the compound agent to the polyaluminum chloride of 1-10 ppm, and the iron ions can be removed from the polyaluminum chloride to a degree that the iron ions cannot be detected, so that the aim of purification and decolorization is achieved; additionally-added chemical agents, such as activated carbon and the like, are not needed to be adopted, and the iron ions can be effectively removed from the polyaluminum chloride by adding the compound agent during the process of preparing the polyaluminum chloride or directly adding the compound agent into the polyaluminum chloride, so that the method for removing the iron ions from the drinking-water-level polyaluminum chloride has the characteristics of simplified decolorization process, short reaction cycle, high utilization ratio of raw materials, no pollution, and the like. |
