通过铁、锰盐改性粘土材料制得一种新型除铁材料FMC,并采用静态和动态试验考察了FMC的除铁性能及影响因素。结果表明,改性粘土材料对铁表现出稳定、优良的吸附性能,在pH值为4～8的范围内可保持94%以上的除铁能力,对铁的饱和吸附量高达9.28 mg/g,且在1 h内即可达到吸附平衡。FMC吸附铁的过程符合Langmuir模型,表明该吸附过程属于单分子层吸附模式。采用2%的KMnO4溶液可对FMC材料进行稳定地再生,且再生率>99%。FMC材料在高铁饮用水安全处理方面具有较高的实用价值。 A new type of iron-removing material FMC was prepared from iron and manganese salt modified clay materials. The static and dynamic tests were conducted to investigate the properties and influencing factors of iron removal from FMC. The results show that the modified clay material shows stable and excellent adsorption properties to iron, maintains 94% of its iron removal ability in the pH range of 4 ~ 8, and has a saturated adsorption capacity of 9.28 mg / g, And within 1 h to reach adsorption equilibrium. The adsorption of iron by FMC conformed to the Langmuir model, indicating that the adsorption process belongs to the monolayer adsorption mode. The FMC material can be regenerated stably with 2% KMnO4 solution, and the regeneration rate is> 99%. FMC materials in high-speed rail drinking water safety treatment has a high practical value.
