Abstract
The use of waste of kepok banana’s peel to adsorb lead(II) metal ion was done. Peel of kepok banana was activated by using nitric acid before used as adsorbent. The optimum time needed by kepok banana’s peel to adsorp lrad(II) metal was 45 minutes with adsorbed metal was 41.779%. Adsorption kinetics of lead(II) at kepok banana’s peel follows kinetic model of Ho pseudo second with the value of R2 is 0.997 and k was 0.063 minutes-1. Isothermal adsorptions from lead(II) on kepok banana’s peel follows Freundlich adsorption model with R2 was 0.893 and capacity of adsorption was 54.752 mg/gram.
研究了利用香蕉皮废渣吸附铅(II)金属离子的方法。以香竹香蕉皮为吸附剂，先用硝酸对其进行活化。果皮对lrad(II)金属的最佳吸附时间为45 min，吸附率为41.779%。香蕉皮对铅(II)的吸附动力学符合Ho伪秒的动力学模型，R2为0.997,k为0.063 min -1。香蕉皮对铅(II)的等温吸附符合Freundlich吸附模型，R2为0.893，吸附量为54.752 mg/g。
