Bio-sorption of a bi-solute system of copper and lead ions onto banana peels: characterization and optimization.

ABSTRACT:

Purpose

Banana peel was used as a low-cost adsorbent for the removal of Cu and Pb ions from aqueous solution in a binary system.

Methods

The interactive effects of the operating parameters such as initial concentration, pH, adsorbent dosage and particle size were studied in a batch mode using central composite design. The characterizations of banana peels were done using point of zero charge (pHpzc), Fourier infrared transform (FTIR), scanning electron microscopy (SEM) and elemental composition (EDS).

Result

The point of zero charge of banana peels was determined to be 4.83. The FTIR, SEM and EDS showed the functional groups, surface morphology and elemental composition respectively before and after the adsorption process. The analysis of variance (ANOVA) showed a goo
