Saccharomyces Cerevisiae as Adsorbent for Copper Removal

摘要：

This paper studied the adsorption kinetic and thermodynamic characteristics on copper by saccharomyces cerevisiae, and superiority and feasibility by saccharomyces cerevisiae as an adsorbent for copper removal in comparison with active carbon. The adsorption process conforms to Thomas kinetic equation, relativity coefficient of R is 0.8598, with C0 and Q 20 mg·L-1 and 2 mL·min-1, maximum adsorption capacity can be achieved. Langmuir and Freundlich thermodynamic equations apply to the adsorption process. Langmuir equation is better with R2 0.9291 and maximum adsorption capacity 4.8239 mg·g-1. Breakthrough curves of saccharomyces cerevisiae and active carbon on copper removal look alike. Adsorption capacities are 5.421 mg·g-1 and 3.987 mg·g-1 respectively. Saccharomyces cerevisiae is a superior adsorbent with high adsorption capacity and low cost.
