چکیده انگلیسی
The efficiency of a locally available very low cost waste tire rubber granule in removing anionic surfactant (AS) by adsorption process was evaluated. As a representative member of AS sodium dodecyl sulfate (abbreviated as SDS) was used. It was found that in the batch experiment conducted at 2.0Â mg/l initial concentration of SDS, rubber granules could remove up to 92% of SDS from wastewater. Kinetic profiles under various conditions were developed. The equilibrium time was found to be 6Â h. Reaction rate constants (forward, reverse and overall) were determined for different initial concentrations of SDS by approximating the kinetic data to the first-order reversible kinetic model. Pore and film diffusion coefficients were determined from the half-time equations and film diffusion appeared to be rate limiting. This was further supported by multiple interruption tests.
