Kinetic study of adsorption of heavy metals on blast furnace slag
In this paper, blast furnace slag was investigated as a potential adsorbent for the removal of zinc and copper ions from the aqueous solution. The adsorption was performed by a static, so - called "batch" process. Adsorption properties were studied by monitoring the influence of contact time adsorbent with adsorbate. Performed studies have shown that the equilibrium in the tested system is achieve in 30 minutes. Intraparticle diffusion model, heterogeneous diffusion model and film diffusion model were used to test the zinc and copper ion diffusion in a competitive adsorption. The obtained results showed that intraparticle diffusion contr olled the adsorption process.
