A brief review of “Eco-Friendly Approach to Textile Wastewater Treatment: Activated Date Palm Fibres as Bio-Adsorbents for Malachite Green.”

The swift evolution of global society and the substantial population growth have led to increased human activities involving the processing and industrial production of dyes. These activities have resulted in severe environmental damage and pose significant risks to human health. Dyes are a principal pollutant from industries being discharged into water, and handling them has become a major issue. Industrial wastewater containing dyes presents considerable environmental hazards due to its potential carcinogenic, cytotoxic,mutagenic effects on ecological as well ashuman health.Current generation faces a significant challenge in removing non-biodegradable pollutants, prompting extensive research on adsorbing these contaminants from aquatic environments. The paper focuses on malachite green (MG), dye usually found in textile, printing, as well as paper industry effluents, along with other frequently used cationic dyes in industrial processes. Commercially available activated carbons (ACs) are neither cost-effective nor environmentally sustainable. Renewable and biodegradable materials are being explored as potential precursors for activated carbon synthesis, with date palm fiber residues garnering significant attention because of their high lignocellulosic content as well as low ash composition. The present research aims to thoroughly examine the efficacy of date palm and its derived activated carbons as adsorbents.Based on experimental results, a comprehensive analysis was conducted on various factors involving initial temperature, adsorbent dosage, dye concentration, pH, agitation, particle size, contact time, as well as stirring. Equilibrium data was examined using Freundlich and Langmuirisotherms.Kinetic analyses have been performed to identify most suitable method to characterizing the adsorption process.
