摘要: 以香蕉皮为原料用乙酸对其进行改性，得到改性香蕉皮吸附剂，将改性香蕉皮吸附剂用作吸附载体，考察其对废水中Pb²⁺的循环吸附性能.结果表明：用乙酸对香蕉皮进行改性能明显提高其比表面积和孔体积，为废水中Pb²⁺的吸附提供了有利的条件；改性香蕉皮吸附剂对废水中Pb²⁺的吸附性能更好，吸附效率达到97.9%，4次循环吸附后，其吸附效率仍可保持在92.1%.

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.
