Abstract
Purpose
The purpose of this paper is to examine the batch adsorption system of a cationic dye (methylene blue, widely used in various sectors) on two adsorbents; ZSM-5 zeolite which was prepared with the molar composition: 0.2057 Na2O-0.00266 Al2O3-SiO2-0.68 (pyrrolidine)-40 H2O-0.12 H2SO4.
Design/methodology/approach
By the hydrothermal synthesis method, and the purified clay and is analyzed by IR and DRX method.
Findings
For this, the authors conducted a parametric study of adsorption and effect of several important parameters on the adsorption of BM on the material used, in particular, the contact time (equilibrium is established after 120 min), different concentrations of adsorbents, different masses, the pH and temperature. The experiments demonstrated the crucial role of these parameters. A kinetic study was done and kinetic models were applied to the experimental results such as the pseudo-first order, pseudo-second order.
Originality/value
This work is original.
