水中刚果红的磁性活性炭／纤维素微球法脱除
Removal of Congo red in water by magnetic activated carbon/cellulose microspheres
摘要
Abstract
To develop high effective adsorbents for removal of dyes ,the magnetic nanoparticles and acti-vated carbon powders were embedded in cellulose matrix to fabricate a bioadsorbent .The effects of dos-age of microspheres ,initial concentration of Congo red ,pH ,time and temperature on the removal rate of Congo red were studied .Results show that the dosage of wet adsorbent with Congo red adsorption is 25 g ;the adsorption reaches equilibrium in 20 minutes ;removal rate of Congo red reaches 96 .4% at pH of 7 .50 at the room temperature;temperature has a greater influence on the adsorption process ,which is best at 40 ℃ .The isothermal adsorption behavior of magnetic cellulose composite microspheres on Congo red can be described by Langmuir and Freundlich equation ,and the adsorption process is physi-cal adsorption and chemical adsorption .关键词
