| Abstract: |
| In this study， cellulose was used as the raw material， and it was esterified by polyacidic anhydride to prepare the carboxylated modified cellulose material （Cell-COOH）.The preparation conditions of Cell-COOH were optimized through one-factor experiment， the structure of Cell-COOH was characterized， and its adsorption properties and behaviors were investigated. The results showed that the equilibrium adsorption capacity of Cell-COOH on 20 mg/L amphetamine solution was 34.59 mg/g under the conditions of cellulose to homophthalic anhydride mass ratio of 1∶3， reaction temperature of 115 ℃， and reaction time of 1.5 h. The adsorption behavior of Cell-COOH towards amphetamine was in accordance with the Langmuir isothermal model and the pseudo-second kinetic model， which was mainly single-layer-chemisorption， and the adsorption process was a self-motivated exothermic reaction. The adsorption capacity of Cell-COOH towards amphetamine was 92.64% of first adsorption after 7 cycles of adsorption-desorption experiments， showing a good stability and reusability. |
