In the present work, we have developed a mesoporous silicalite-1 using CMC as a template for the removal of MB from aqueous solution. The synthesized silicalite-1 were characterized using scanning electron microscopy (SEM), transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), thermogravimetric analysis (TGA), Energy-dispersive X-ray spectroscopy (EDAX) and N₂ adsorption–desorption isotherm (BET). XRD and FT-IR analysis confirmed the formation of crystallinity and development of MFI structure in the mesoporous silicalite-1. The adsorption of MB dye on mesoporous silicalite-1 was conducted by batch adsorption method. The effect of various parameters such as adsorbent dosage, initial dye concentration, contact time and temperature on the dye uptake ability of silicalite-1 was investigated. The operating parameters for the maximum adsorption are silicalite-1 dosage (0.1 wt%), contact time (240 min), initial dye concentration (10 ppm) and temperature (30 ℃). The MB dye removal onto mesoporous silicalite-1 followed pseudo-second-order kinetic and Freundlich isotherm. The silicalite-1 exhibits 86% removal efficiency even after six adsorption–desorption cycle. Therefore, the developed mesoporous silicalite-1 is an effective eco-friendly adsorbent for MB dye removal from aqueous environment.

在目前的工作中，我们使用 CMC 作为模板开发了一种介孔硅沸石-1，用于从水溶液中去除 MB。使用扫描电子显微镜 (SEM)、透射电子显微镜 (TEM)、傅里叶变换红外光谱 (FT-IR)、X 射线衍射 (XRD)、热重分析 (TGA)、能量色散 X射线光谱 (EDAX) 和 N ₂吸附-解吸等温线 (BET)。XRD 和 FT-IR 分析证实了在介孔硅沸石-1 中结晶的形成和 MFI 结构的发展。MB染料在介孔硅沸石-1上的吸附采用间歇吸附法。研究了吸附剂用量、初始染料浓度、接触时间和温度等各种参数对silicite-1上染能力的影响。最大吸附的操作参数是硅沸石-1 用量（0.1 wt%）、接触时间（240 min）、初始染料浓度（10 ppm）和温度（30 ℃）。MB染料在介孔硅沸石-1上的去除遵循准二级动力学和Freundlich等温线。即使经过六次吸附-解吸循环后，Sisillite-1 仍表现出 86% 的去除效率。所以，
