摘要

本研究采用煅烧蛋壳（CE）作为吸附剂从溶液介质中去除维多利亚蓝R（VBR）染料。为此，研究了pH、相互作用时间、吸附质浓度、吸附剂用量和盐效应参数，以确定合适的吸附条件。在pH为2、吸附剂浓度为2.0g/L、搅拌时间为5分钟的条件下，吸附率最高。在最佳吸附条件下，染料去除率达97%。实验结果表明，该吸附机理符合拟二阶动力学模型和Langmuir等温线模型。用扫描电镜和红外光谱对CE进行了表征。

Calcined Eggshell for Removal of Victoria Blue R Dye from Wastewater Medium by Adsorption

In this study, the use of calcined eggshell (CE) as an adsorbent in removing Victoria Blue R (VBR) dyestuff from the solution medium was investigated. For this purpose, pH, interaction time, adsorbate concentration, amount of adsorbent, and salt effect parameters were studied to determine the appropriate adsorption conditions. The highest adsorption yield was obtained at pH 2, 2.0 g/L adsorbent, and a stirring time of 5 minutes. 97% of the dye was removed under optimum adsorption conditions. The results obtained from the experimental studies showed that the adsorption mechanism is compatible with the pseudo-second-order kinetic model and the Langmuir isotherm model. SEM and IR analysis were performed for the characterization of CE.
