Abstract: The novel cellulose resin crosslinked with perylene tetracarboxylic diimides 3 was synthesized and its structure was characterized by elemental analysis, Fourier transform infrared spectroscopy(FT-IR) and scanning electron microscopy(SEM). Dye adsorption experiments of polymer 3 suggested that it exhibited excellent adsorption capacities for four tested dyes[orange G sodium salt(OG), brilliant ponceau 5R(BP), methylene blue(MB) and crystal violet(CV)]. The adsorption capacities for OG, BP, MB, CV were as high as 1.04, 1.21, 1.14 and 0.96 mmol/g, respectively. The adsorption processes obeyed a pseudo second-order model, followed the Langmuir isotherm equation, and were exothermic and spontaneous. The pH values between 2~12 had slight influences on adsorption capacities. The adsorption results indicated that the electrostatic action, hydrogen bond and π-π stacking action played important roles in adsorption processes.
