Fig. 4From: Facile synthesis of surface-functionalized magnetic nanocomposites for effectively selective adsorption of cationic dyesAdsorption of cationic dyes on Fe3O4/PCC MNPs (a) pseudo-second-order kinetics (b) pseudo-first-order kinetics. As shown as Fig. 4, the blank line represent the adsorption of MB, the red line reperesent the adsorption of GB, the blue line represent the adsorption of MG, the magenta represent of CV adsorption, and the olive is on behalf of the adsorption of FGBack to article page
