Abstract
This study focuses on understanding biosorption with an objective of exploring low-cost
adsorbents using chemically activated banana and orange peels powder for removal
of Pb (II) ions from the aqueous solution. The impacts of several environmental
factors like pH, adsorbent dose, contact time and metal ion concentration have been
analysed on the adsorption behaviour of the adsorbents. The activated adsorbents
were characterised by Fourier transform infrared spectroscopy (FTIR). The effects
of various parameters such as adsorbent dosages, contact duration, pH and metal
ion concentration were investigated with help of batch experiment method.
Various isotherm models were employed to analyse and to interpret the experimental
data. Among these, the Langmuir isotherm models were the most accurate in describing
the adsorption behaviour of both adsorbents. This research would be significant
because continuous research and development efforts are essential for improving
the effectiveness of heavy metals adsorption process by banana and orange peels.
