Abstract
This study explores the adsorptive properties of high silica-containing
zeolite synthesised from natural sediments rich in aluminosilicates,
modified with biowaste silica for wastewater treatment.
Hydrothermal synthesis was used to produce zeolite from local clay
sediment. The synthesised zeolite was tested for its ability to adsorb
ionic dyes from textile wastewater. XRD and EDS analysis revealed a
faujasite zeolite-Y with 85.60 g of Si and 17.50 g of Al, and a Si/Al
ratio of 4.891 g/mol. The Zeolite Y particles had a uniform size
distribution ranging from 1 to 3 μm. The Langmuir isotherm analysis
showed a specific surface area of 1,750 m²/g and a pore diameter of
1.847 nm. Batch adsorption experiments yielded Langmuir,
Freundlich, and Temkin regression constants with R² values below
0.9924, 0.9451, and 0.9395, respectively, during an isothermal study
on methylene blue sorption. The fixed-bed column test indicated an
adsorbent stability of 5.25 hours. Overall, the faujasite zeolite-Y, with
its large mesoporous structure, demonstrates significant adsorption of
ionic dye from textile effluent.
