Potential use of grape waste as a bioadsorbent to remove copper and cadmium from liquid effluents Pontificia Universidad Católica del Perú - (PE), Perú A major source of water pollution from mining is acid mine drainage, produced by the oxidation of minerals with high sulfide content. Currently, the possibility of using bioadsorbents to remove heavy metals has become an attractive alternative. This article presents preliminary results on the removal of copper and cadmium using grape waste from the wine industry. Through batch removal trials, optimal removal conditions will be established by monitoring the amount of biosorbent, effluent volume, contact time, and temperature. The final concentration of each contaminant will be determined using atomic absorption spectroscopy (AAS). The maximum removal percentage will also be determined for each contaminant. Removal tests demonstrate that it is possible to remove up to 71% of copper and 34% of cadmium. The Langmuir model fit better than the Freundlich model for copper (R² = 0.876) and cadmium (R² = 0.957) adsorption in grape pomace. The aim is to use waste from the wine industry as an efficient, economical, and eco-friendly bio-additive, making it an attractive and competitive alternative to other contaminant removal technologies for mining effluents. | |
