摘要
采用溶胶-凝胶法制备出多孔活性氧化铝,采用XRD表征手段对其和参比成品活性氧化铝的晶相进行分析。XRD测定表明实验条件下制得的活性氧化铝为非晶态的γ-Al2O3,成品活性氧化铝为结晶完整的γ-Al2O3。用静态吸附法比较了制备的活性氧化铝、成品氧化铝对氟离子的吸附性能,结果表明:实验制得的活性氧化铝对氟离子的吸附性能较好。
The sol-gel method was used to prepare the porous activated alumina,XRD was used to analyze the crystal phase of the finished activated aluminum.XRD determinations indicated the activated alumina obtained in the experiment was amorphous γ-Al2O3,and the prepared activated alumina was perfectly crystallized γ-Al2O3.The static adsorption method was adopted to compare the adsorptive performance of the prepared activated alumina obtained and the finished activated alumina on the fluoride,experimental results showed that the prepared activated alumina had better adsorption on the fluoride.
