| Abstract: | The removal of phenol from solution was investigated using macroporous resin. The effects of initial concentration, pH, and temperature on phenol removal were studied. The experimental results indicated that the adsorption capacity reached equilibrium state within 20 min and adsorption followed pseudo‐second‐order kinetic model. Langmuir isotherm model could be better to describe the isothermal adsorption of phenol, the maximum adsorption capacity (Qm) and Langmuir constant (KL) were 103.64 mg/g and 0.2719. Macroporous resin after reached to saturation has a high desorption percentage, indicating that H‐103 is an excellent reusing adsorption material. It provided theoretical references for practical application in phenolic wastewater treatment. |
