Abstract |
The present study aimed to evaluate the adsorption capacity of unmodified banana peel for Pb(II) removal from a synthetic solution. The influence of pH, mass, and contact time was evaluated in batch tests. Also, column tests were performed aiming to develop a filter for facilitating its use in the industry. The activated carbon was used for comparison. The Pb(II) removal efficiency reached 93.7% and 74.8% for the batch and column tests, respectively, under optimized conditions (pH = 3, adsorbent mass =1 g, contact time = 30 min). However, the column test presented higher adsorption capacity of Pb (0.5 mg g(-1)) than the batch test (0.2 mg g(-1)). The pH was an important factor in the adsorption process. Banana peels presented greater efficiency of Pb(II) removal than the traditional activated carbon. Thereby, this study proposed to improve the treatment of water and wastewater in a sustainable, effective, and low-cost manner. |
