Abstract
Integrated wastewater handling and organic dye management are important challenges that scientists are working to solve today. A thiol-functionalized ionic liquid-based periodic mesoporous organosilica (PMO-IL-SH) has been prepared and characterized using diffuse reflectance infrared Fourier transform, scanning electron microscopy, transmission electron microscopy and thermal gravimetric analysis and applied as a robust adsorbent for removal of methylene blue (MB) as an organic dye from an aqueous solution. The optimized conditions were achieved by using 0.04 g of PMO-IL-SH, 10 mg L−1 of MB at 35 min of contact time and pH 8. Fitting the equilibrium data shows the suitability of the Langmuir model with a second-order equation to control the kinetics of the adsorption process with the adsorption capacity of 384.61 mg g–1. This study may provide insight for remarkable removal of organic dyes to refine water challenges.
