The adsorption of lead(II) and cadmium(II) on peels of banana has been studied in batch mode using flame atomic absorption spectroscopy for metal estimation. Concerned parameters like adsorbent dose, pH, contact time and agitation speed were investigated. Langmuir, Freundlich and Temkin isotherms were employed to describe adsorption equilibrium. The maximum amounts of cadmium(II) and lead(II) adsorbed (qm), as evaluated by Langmuir isotherm, were 5.71 mg and 2.18 mg per gram of powder of banana peels, respectively. Study concluded that banana peels, a waste material, have good potential as an adsorbent to remove toxic metals like lead and cadmium from water.
使用火焰原子吸收光谱法研究了香蕉皮对铅(II)和镉(II)的吸附，用于金属测定。研究了吸附剂用量、pH 值、接触时间和搅拌速度等相关参数。采用朗缪尔、弗伦德利希和坦金等温线描述吸附平衡。根据朗缪尔等温线评估的香蕉皮粉末对镉(II)和铅(II)的最大吸附量（qm）分别为 5.71mg 和 2.18mg/g。研究表明，香蕉皮作为一种废物，具有良好的潜力，可以作为一种吸附剂，从水中去除铅和镉等有毒金属。
