【摘要】 目的探讨饮水降氟剂五羟基氯化铝降氟的试验影响因素及降氟效果,为五羟基氯化铝作为饮水降氟剂提供理论依据。方法以五羟基氯化铝处理6种不同浓度的高氟水,对五羟基氯化铝的碱化度、降氟的稳定性进行分析,同时与同类铝盐降氟剂进行比较。结果五羟基氯化铝碱化度达到最高即83.3%,6种不同浓度高氟水,降氟的相对标准偏差为1.32%～9.52%,与同类铝盐降氟剂比较,其降氟效率最高。结论五羟基氯化铝降氟效率较高,不改变原水水质,降氟效果稳定,成本低,卫生安全,具有实际应用的前景。更多还原

【Abstract】 [Objective]To explore the effect and influencing factors of removing fluoride from water by pentahydroxyl aluminum chloride,and provide theoretical evidence for its effect of removing fluoride. [Methods]High fluoride water at 6 different concentrations was treated with pentahydroxyl aluminum chloride.The reliability of the defluoridation performance and the alkalization degree of pentahydroxyl aluminum chloride were analyzed,then the results were compared with the similar defluoridation agents. [Results]Pentahydroxyl aluminum chloride had the highest alkalization degree of 83.3%.The relative standard deviation for defluoridation of high fluoride water at 6 different concentrations was 1.32%-9.52% which was highest among similar defluoridation agents. [Conclusion]The defluoridation effect of pentahydroxyl aluminum chloride is obvious,stable,hygienic and safe,with low cost and no water quality change.It is suitable for practical application.更多还原
