Synthesis and Characterization of Layered Silicate Na-Magadiites and its Application in Pollution Control

Advancements in several industrial fields contribute to environmental pollution, predominantly after using essential heavy metals, organic compounds (including pharmaceuticals and dyes), and gaseous emissions such as carbon dioxide (CO₂), often released into the environment without prior treatment. Consequently, it enriches the pollution of water resources and bacteria in the soil. Researchers are searching for cost-effective and innovative methods, including synthesizing harmless active compounds to minimize the toxic effects of discharged waste products. This article provides the synthesis and characterization of the Layered Silicate Na Magadiites (LSNaM.), which have a unique structure where each layer is interconnected with tetrahedra. The synthesized LSNaM is characterized by nitrogen adsorption, thermogravimetry, X-ray diffraction, and scanning electron microscopy, and it was applied to laboratory-prepared dye wastewater. Results showed that the LSNaM exhibited significantly higher adsorption capacities for the reactive active blue dye (RB) with slow adsorption kinetics, and equilibrium typically reached within 3 to 4 hours. Moreover, the data were best described by a pseudo-first-order kinetic model. Additionally, the impact of pH on the adsorption process was investigated at ambient temperature. The findings suggest that LSNaM has the potential to serve as an efficient and cost-effective material for removing organic contaminants, such as dyes and organic pharmaceutical waste discharged in soil and streams.
