Abstract:
This research study investigates the adsorption properties of Snail Shell as an adsorbent
material for removing contaminants. Various parameters such as contact time and
adsorbent dose were examined to determine their influence on the adsorption process
and removal efficiency. The study also employed Langmuir and Freundlich isotherm
models to analyse the equilibrium data.
The results of the experiments revealed that the percentage removal efficiency of Snail
Shell increased as the contact time and adsorbent dose increased. However, it decreased
with higher concentrations of the dye being adsorbed. The isothermal analysis indicated
that the Langmuir model provided the best fit for the equilibrium data, as evidenced by
a high correlation coefficient value (R2 = 0.8648) for the Snail Shell adsorbent
(Bellamya bengalensis).
Further analysis of the data plotted in Excel demonstrated that the percentage removal
efficiency of Snail Shell increased with higher masses of the adsorbent. Moreover, the
use of a higher adsorbent dose resulted in comparable adsorption performance to that of
charcoal, a commonly used adsorbent material.
Overall, this study highlights the adsorption properties of Snail Shell and its potential as
an effective adsorbent for contaminant removal. The findings suggest that Snail Shell
exhibits favourable adsorption characteristics, with improved performance observed at
longer contact times and higher adsorbent doses. The Langmuir model provides a
suitable representation of the equilibrium data, indicating the formation of monolayer
adsorption on the Snail Shell surface. The research contributes to the understanding of
Snail Shell's adsorption behaviour and offers insights into its practical application in
water treatment and other environmental remediation processes.
