Abstract

Aimed to prepare high efficient dye sorbent and control water pollution, herein we utilized solvothermal method to synthesize porous polyimide (PI) polymer with a large surface area using DMSO as solvent. Unlike the solid-state thermal polymerized PI with low surface area of 5 m2g−1, this PI material prepared in DMSO solvent possessed a large surface area of 430 m2g−1, which was beneficial for adsorption of organic dye in waste water, achieving a max MO adsorption of 200 mg g−1 three times higher than that of multiwalled carbon nanotube. The adsorption kinetics of dye molecules on PI was investigated in detail and the R2 value of 0.99071 for pseudo-second-order model confirms the adsorption was fitted best with Langmuir isotherm.
