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

水中有害染料的释放增加，加上世界淡水供应的不断减少，使纺织业承受着安全有效地处理废水的更大压力。反应性染料对自然分解的抵抗力突出了对专门去除方法的需求。对低成本，高效吸附剂的不断增长的需求已导致对生物启发性二氧化硅（BIS）的探索，因为它们具有绿色合成，经验证的可扩展性和清除染料所需的化学功能化的多功能性。通过系统的方法，研究了使用一系列BIS从水中去除活性蓝19的情况，并将其与使用市售吸附剂的去除率进行了比较。商业吸附剂的去除率为0％，而BIS的去除率高达94％。从动力学研究中获得的结果表明是假二级反应，表明通过静电相互作用的化学吸附过程。使用等温模型（Langmuir和Freundlich）检查各种吸附条件（温度，pH，吸附剂和染料浓度）的影响表明，吸附具有化学和物理性质。吸附机理的研究表明，染料在BIS上的吸附是自发的。BIS表现出更高的吸附容量（334 mg g 吸附机理的研究表明，染料在BIS上的吸附是自发的。BIS表现出更高的吸附容量（334 mg g 吸附机理的研究表明，染料在BIS上的吸附是自发的。BIS表现出更高的吸附容量（334 mg g^-1）与文献实例相比，在酸性条件下具有快速吸附，出色的热稳定性和良好的再利用潜力。这些发现凸显了BIS作为可持续，高效和低成本吸附剂的潜力，可以提出以供将来实施。
