Decontamination of Anthraquinone Dyes Polluted Water Using Bioinspired Silica as a Sustainable Sorbent

The increased release of harmful dyes in water, along with the continuous reduction world’s freshwater supplies has placed textile industry under greater pressure to safely and effectively treat wastewater effluents. Resistance reactive breakdown naturally highlighted need for specialised removal methods. growing low-cost, efficient sorbents led exploration bioinspired silicas (BIS) due their green synthesis, proven scalability, versatility chemical functionalisation required dye scavenging. Through a systematic approach, Reactive Blue 19 from water was studied using range BIS, compared commercial sorbent. While 0% denoted sorbent, BIS showed up 94% removal. results obtained kinetic study suggested pseudo-second-order reaction, indicating chemisorption process via electrostatic interactions. Examination effects various adsorption conditions (temperature, pH, sorbent concentrations) isotherm models (Langmuir Freundlich) indicated that both physical nature. mechanism suggest on spontaneous. higher capacity (334 mg g−1) literature examples, rapid acidic conditions, excellent thermal stability good reuse potential. These findings highlight potential as sustainable, low-cost could be brought forward future implementation.
