Modelling studies for the adsorptive eradication of a dye Rose Bengal dye in aqueous solutions using an adsorbent perlite have
been exploited. A batch mode adsorption technique was performed to find the influence of contact time, strength of the Rose bengal
dye, dosage of the perlite, pH and temperature. The equilibrium of the adsorption has been achieved only after the contact time of
40 min. The kinetic behaviour of the adsorption has been evaluated using the pseudo first-order as well as the second-order types.
The achieved kinetic equation statistics of pseudo second-order kinetic equation has a close proximity with unity. Equilibrium
adsorption values are obtained from the Freundlich and Langmuir isotherm. From the correlation data, Freundlich isotherm remains
suited to describe the adsorption behaviour of Rose bengal dye on the perlite. From the experimental data, the thermodynamic
parameters like ∆Ho, ∆So, and ∆Go are assessed. The calculated result was shown that the adsorption behaviour is exothermic as
well as immediate in description. The dimensionless separation factor has been shown that perlite is the substitute to other
adsorbents for the elimination of rose Bengal dye from the aqueous solution.
