Study on adsorption capacity of uranium tailings-based porous ceramisite for hydroquinone
摘要
Abstract
Taking uranium tailings treated to hazard-free as the main raw material,a new type of environment fuctional material-uranium tailings-based porous ceramisite was prepared.The adsorption capacity of uranium tailings porous ceramisite for hydroquinone were investigated.The results indicated that,the removal rate and adsorption capacity of uranium tailings-based porous ceramisite for hydroquinone uranium tailings were 91.2%and 4.56 mg/g respectively with a pH value of 7.During the adsorption of the uranium tailing-based porous ceramsite for hydroquinone,the liquid film diffusion dominated and was more accurately described by the pseu-do-first-order kinetic equation.Data fitting degree of Langmuir equation and Koble-Corrigan equation of adsorp-tion isotherm was higher.The adsorption properties of uranium tailings-based porous ceramsite were fixed at a fixed site by a single layer molecular layer,and it was a non-uniform composite adsorption system.The adsorp-tion process of uranium tailings porous ceramisite for hydroquinone was a high fitting for the liquid film diffu-sion model.The R2and k value were 0.847 8 and 0.041 7 respectively.关键词
