摘要

天然资源广泛、易得，对去除废水中的有机染料具有重要意义。研究了Jemma Silica Sand (JSS)和甘蔗甘蔗渣ash (SCBA)对水中甲基蓝(MB)的去除效果。XRD分析表明，JSS和SCBA均为结晶，但JSS的晶粒尺寸为56.27 nm, SCBA的晶粒尺寸为70.90 nm。此外，XRF结果证实，JSS中二氧化硅的含量为98%，SCBA中二氧化硅的含量为71.5%。通过SEM和EDX分析了两种材料的形貌和元素组成。由于SCBA具有较高的孔隙率，其对MB的去除率(~99.14%)高于JSS(~93.75)。SCBA对MB的吸附符合Freundlich等温线模型和表明化学吸附的拟二级动力学模型。因此，SCBA具有高效、经济、环保的特点，是去除废水中MB的有效吸收剂。

Comparative Study on Removal Efficiency of Methylene Blue from Wastewater by using Nano-Scaled Sugarcane Bagasse Ash and Jema Silica Sand

The widely available and easily accessible natural resources are very important to remove organic dyes from wastewater. Here in this work, Methyele Blue (MB) removal efficiency of Jemma Silica Sand (JSS) and Sugar Cane Bagasse ash (SCBA) from aqueous solutions was investigated. The XRD patterns revealed that both JSS and SCBA are crystalline, but the crystalline size of JSS is 56.27 nm and that of SCBA is 70.90 nm. In addition to the percentage of silicon dioxide in JSS was 98% and in that of SCBA was 71.5% as confirmed by XRF results. The morphology and elemental composition of the two materials were revealed by SEM and EDX. The MB removal efficiency of SCBA (~99.14%) is greater than that of JSS (~93.75) because of its higher porosities nature. The adsorption of MB by SCBA follows the Freundlich isotherm model and pseudo-second-order kinetic model indicating chemisorption. Therefore, SCBA is promising absorbent for removing MB from wastewater because of its efficient, cost-effectiveness, and environmentally friendly nature.
