The absorption properties of polyester grafted with acrylic acid（PET-g-AA）were studied.The polyester fiber was grafted firstly and then theoretical analysis and adsorption experiments were carried out on it.Freundlich and Langmuir isotherm equation with pseudo-second-order kinetic model were adopted to describe the adsorption process.The experiments find that adsorption quantity is related to parameters,including temperature,pH value,adsorption time and concentration of cationic dye,whose process is highly consistent with theory analysis.Results indicated that grafted polyester fiber was an attractive substance for removing cationic dyes from dye waste and the maximum adsorption capacities was 246.9mg/g.
