硫酸铜含量和不同助剂对椰壳活性炭氨气防护效果的影响研究
Study on the Effects of Copper Sulfate Content and Different Additives on the Ammonia Protection Efficiency of Coconut Shell Activated Carbon
通过改变浸渍液中硫酸铜含量并加入不同助剂 (盐酸和磷酸),文章研究了硫酸铜含量和助剂对椰壳活性炭氨气防护效果的影响,确定了最佳浸渍液配比;通过比表面积分析仪、扫描电镜-能谱仪、X射线粉末衍射仪对浸渍炭和基炭的孔径分布、表面形貌和物相结构进行了分析。结果表明,浸渍炭的氨气防护效果由硫酸铜含量、助剂种类及含量共同决定;在测试的2种助剂中,磷酸的氨气防护效果优于盐酸;最佳浸渍液配比为30 mL磷酸和3%硫酸铜 (以铜离子相对基炭质量比计)。
The effects of copper sulfate concentration and diverse additives on the ammonia adsorption capacity of coconut shell-derived activated carbon were examined in this study. The most effective impregnation solution composition was ascertained by modulating the copper sulfate concentration in the impregnation solution and introducing various additives. The pore size distribution, surface topography, and phase structure of both the impregnated and base carbons were characterized using a surface area analyzer, scanning electron microscope-energy dispersive spectrometer (SEM-EDS), and X-ray powder diffractometer. The findings revealed that the ammonia adsorption efficacy of the impregnated carbon is influenced by the concentration of copper sulfate and the type and quantity of additives introduced. In the comparative evaluation conducted within this study, Phosphoric acid demonstrated superior performance in ammonia adsorption compared to hydrochloric acid. The most optimal impregnation solution ratio determined was a combination of 30 mL of phosphoric acid and 3% copper sulfate, based on the mass ratio of copper to the base carbon.
