活性氧化铝去除水中四氯化碳的实验研究

In order to investigate adsorption characters and influencial factors of the adsorption of carbon tetrachloride by activated alumina, this paper chooses activated alumina as reaction medium, through the batch experiments, we get certain conclusions that the reaction corresponds to Langmuir isotherm, the adsorption kinetics process accords with inter-particle diffusion equation and the saturated adsorption capacity is 821μg/g. The initial concentration of carbon tetrachloride, pH and size of activated alumina are taken into account while investigating the influence on adsorption efficiency. The optimum conditions for adsorption are determined as follows: the adsorption equilibrium time is 30 min, the suitable size of activated alumina is about 3 to 6mm, pH is approximately 7. The adsorption of carbon tetrachloride by activated alumina is owing to physical adsorption.
