The present investigation assessed the applicability of incense stick ash, a novel and sustainable adsorbent for remediation of Victoria Blue dye from wastewater. Incense stick ash, without any physical and chemical treatment has been applied to investigate the influence of various experimental parameters as pH, loading of adsorbent, concentration, shaking time, temperature and ionic strength on Victoria Blue remediation in a batch operation. Incense stick ash was characterized using BET, DLS, SEM-EDS, FTIR and XRD techniques. BET surface area, pore volume and pore diameter of incense stick ash are obtained as 2.245 m² g⁻¹, 0.0118 cm³ g⁻¹ and 21.02 nm, respectively. Average particle size of the adsorbent is obtained as 293.2 nm. Goodness of the fit of isotherm and kinetic model to the reported data was identified based on chi squared and coefficient of determination values. Isotherm and kinetic behavior was best represented by Freundlich and pseudo 2nd order equation, respectively. Boyd model confirmed involvement of film diffusion mechanism along with intra-particle for adsorption of Victoria Blue on incense stick ash. Maximum dye uptake was reported as 105.57 mg g⁻¹. Thermodynamic study revealed spontaneous and favorable adsorption of Victoria Blue on incense stick ash at higher temperature. The performed elution and subsequent regeneration study implied desorption capability of incense stick ash and its applicability as a fresh adsorbent for further cycle of adsorption. The overall study implied scavenging potential of incense stick ash, a novel and sustainable adsorbent available at zero cost towards Victoria Blue removal.

本研究评估了香膏灰的适用性，香膏灰是一种新型且可持续的吸附剂，用于从废水中修复维多利亚蓝染料。未进行任何物理和化学处理的熏香灰已用于研究分批操作中各种实验参数（例如pH值，吸附剂的负载量，浓度，振荡时间，温度和离子强度）对维多利亚蓝修复的影响。使用BET，DLS，SEM-EDS，FTIR和XRD技术对香灰进行了表征。BET表面积，孔体积和线香灰分孔径作为2.245米得到² 克^-1，0.0118厘米³ 克^-1和21.02 nm。获得的吸附剂的平均粒径为293.2nm。基于卡方和确定值的系数，确定了等温线和动力学模型对所报告数据的拟合优度。等温线和动力学行为最好分别用Freundlich和伪二阶方程表示。博伊德模型证实了膜扩散机制以及颗粒内部对维多利亚蓝在香灰上的吸附作用。据报道最大染料吸收量为105.57 mg g ^-1。热力学研究表明，在较高的温度下，维多利亚蓝自然而然地吸附在香灰上。进行的洗脱和随后的再生研究表明，香炉灰的解吸能力及其作为新鲜吸附剂用于进一步吸附循环的适用性。总体研究表明，熏香灰具有清除潜力，熏香灰是一种新型且可持续的吸附剂，可以零成本购得，用于清除维多利亚蓝。
