Abstract

The banana peel was used as raw material and modified with acetic acid to obtain modified banana peel adsorbent. The modified banana peel adsorbent was used as adsorption carrier to investigate its cyclic adsorption performance of Pb²⁺ in wastewater. The results showed that the modification of banana peel with acetic acid could significantly increase the specific surface area and pore volume, and provide favorable conditions for the adsorption of Pb²⁺ in wastewater. The modified banana peel adsorbent had better adsorption capacity for Pb²⁺ in wastewater. The adsorption efficiency reached 97.9%, and the adsorption efficiency was still up to 92.1% after 4 cycles of adsorption.
