magnetic chitosan microspheres were prepared by the suspension cross-linking technique.The characterization of scanning electron microscope and optical microscope showed that the microspheres with smooth surface were well shaped.The adsorption capacity of the microspheres for abscisic acid is 8.709×10-5 mol/g at the initial concentration of 32.28 mg/L
and the one step adsorption rate is 89%.Adsorption isotherms fit the Langmuir model well
indicating that the adsorption of abscisic acid on the microsphere is monolayer controlled by chemisorption.And
high correlation coefficient(0.999) was obtained by using the pseudo-second-order kinetic equation to model the adsorption kinetics.
