摘要
The sorption behavior of phenol ontoWasteTire Rubber Particles (WTRPs) was tested at different conditions, which included the effects of contact time, pH value of solution, dosage of rubber particles, initial phenol concentration and temperature. The results showed that the removal rate of phenol could be up to 86% at 25 degrees C when 0.1 g of rubber particles was added, the pH value of solution was 7, the initial phenol concentration was prepared as 20 mg/L and the contact time was 4 h. The relationship between the sorbed quantity of phenol and contact time could be well described with the pseudo-second-order kinetic equation. The sorption capacity of phenol increased with the initial concentration of phenol and decreased with the addition of rubber particles. The relationship between the sorption capacity and equilibrium concentration of phenol was well fitted with Henry model, which indicates that partitioning was the main mechanisms on sorption of phenol No significant effect of pH value of solution and temperature on sorption of phenol was found.
