Application of activated carbon obtained from waste vine shoots for removal of toxic level Cu(II) and Pb(II) in simulated stomach medium

Abstract

Copper and lead ions are the most important toxic metals that cause significant environmental and health problems. In this study, we focused on the development of a very cost-effective and environmentally friendly (renewable) remediation technique using vine sprout, an industrial beer waste and readily available agricultural biowaste. In this study, it was aimed to remove the copper and lead that enter the body for various reasons orally, from the simulated stomach medium (SSM) by adsorption in order to reduce their toxic effects on human health. Activated carbon (ACVS) obtained from vine shoots was used as adsorbent. By preparing an artificial stomach medium, the most suitable adsorption parameters (pH, time, mixing speed, amount of adsorbent, and the effect of other components) were examined in the batch system. Equilibrium adsorption data was interpreted using the Langmuir model. The initial Cu(II) and Pb(II) ion concentrations were 10 mg/L and the adsorbent amount was 0.3 g, and the maximum adsorption efficiency of Cu(II) and Pb(II) ions was 100% in the pH 3.5-6.5 range. The performance variables of the adsorbent used were compared with the performance variables of the commercial activated carbon (CAC) used in the emergency response. It was determined that the adsorbent used was more effective in removing copper and lead.
