The adsorption behaviors of Methylene Blue and Methyl Orange in a diaminoethane sporopollenin-mediated column system

摘要

The adsorption behaviors of Methylene Blue and Methyl Orange on a diaminoethane sporopollenin (DAE-S) solid phase were investigated in a column arrangement,and breakthrough profiles were used in evaluations and quantifications.The adsorption behaviors were evaluated using some common adsorption isotherm models and Scatchard plot analysis.The results showed that the DAE-S was useful for abstracting anionic dyes from cationic dyes.Thus,the usability of a biopolymer derived material (DAE-S) as a cheap,environmentally friendly and effective solid/stationary phase is discussed through the present study,and the adaptability of the DAE-S to common processes performed under column conditions is also drawn in detail.
