text: At low pH values, aniline existed in the form of anilinium ions, and a part of the –NHgroups in chitosan was protonated into –NH, thus it was difficult for the anilinium ions to approach the AC due to the repulsive interaction between the –NHand anilinium ions, leading to low removal toward aniline.
