| 中文摘要 | Red mud (RM), a waste tailing from alumina production, was modified with AlCl(3) (MRMA) and heat activation(MRMAH) for the removal of fluoride from water. The adsorption efficiency and the influences of various factors were investigated, such as reaction time, pH values and dosage of adsorbent. The results showed that the capacity of adsorption of MRMA and MRMAH at 200 degrees C were 68.07 and 91.28 mg . g(-1), respectively, which were much higher than that of RM with 13.46 mg . g(-1). The fluoride concentration after adsorption was below 1 mg . L(-1) according with national drinking water standards. The Langmuir isotherm was the best-fit adsorption isotherm model for the experimental data. The solution pH values affected the removal efficiency significantly, and the highest removal efficiency can be achieved at pH value 7 similar to 8. |
