Study on Adsorption Characteristics of Modified Wheat Straw Cellulose for Aniline
[Purposes]A UV-VIS spectrophotometric method for the determination of aniline was estab-lished by studying the adsorption properties of modified wheatgrass cellulose for aniline.[Methods]The optimum adsorption conditions were explored by changing the experimental variables such as time,ini-tial mass concentration,temperature and pH.[Findings]The adsorption capacity of modified wheatgrass cellulose to aniline increased linearly with the increase of initial concentration,positive correlation.The adsorption of aniline reached the equilibrium in 60 min.At 25℃and pH=8.0,the adsorption rate reached the maximum.[Conclusions]Aniline can be effectively by the modified wheat grass cellulose,and method for determination is simple to operate.
