【 摘 要 】

Abstract The composite consisted of clay and polymers like polyethylene (GCP) was used to remove methylene blue (MB) from the water. The most effective pH, temperature and initial dye concentration in adsorption process were found to be 9, 55 °C and 5 × 10−6 M, respectively. The results of the experiment showed that the adsorption process was compatible with the pseudo-second-order model. Activation parameters of ΔG: − 70.64 K J mol−1, ΔS: − 70.64 J mol−1 K−1, E a: 12.37 K J mol−1 at 308 °C were calculated and showed that adsorption process was exothermic and spontaneous. The results revealed that adsorption of MB on composite GCP was spontaneous and the composite of GCP f could be used for removing of MB from the water.
