Abstract

The present study aimed to evaluate the removal efficiency of two types of cationic dyes of different classes – methylene blue (MB) and malachite green (MG) – from a synthetic effluent using a calcium surfactant (CaSF) originated from used frying soybean oil. The Fourier Transform Infrared Spectroscopy (FTIR) spectra showed that the functional groups present on the surface of CaSF can form surface complexes or bonds with the dye molecules and, consequently, promote their adsorption. The adsorption kinetics studies indicated that the equilibrium point of the process is reached in 90 min for both dyes. Equilibrium studies indicated that the adsorption isotherm models that best fit MB and MG were the Langmuir and the Dubinin–Radushkevich models, respectively. The maximum adsorption capacities of MB and MG, according to the Langmuir model, were 199 and 123 mg·g−1, respectively. In the sight of the high MB and MG removal efficiency (84 and 100%, respectively), the use of CaSF is an excellent alternative for the treatment of effluents contaminated by cationic dyes. The adsorption–desorption cycle studies showed that CaSF maintains a good dye removal efficiency for up to three cycles.

用钙表面活性剂去除合成废水中的阳离子染料
本研究旨在评估使用源自用过的油炸大豆油的钙表面活性剂(CaSF)从合成废水中去除两种不同类别的阳离子染料——亚甲基蓝(MB)和孔雀石绿(MG)的效率。傅立叶变换红外光谱(FTIR)表明,存在于CaSF表面的官能团可以与染料分子形成表面络合物或键,从而促进其吸附。吸附动力学研究表明,两种染料在90分钟内都达到了平衡点。平衡研究表明,最适合MB和MG的吸附等温线模型分别为Langmuir模型和Dubinin–Radushkevich模型。根据Langmuir模型,MB和MG的最大吸附量分别为199和123mg·g−1。鉴于MB和MG的高去除效率(分别为84%和100%),使用CaSF是处理被阳离子染料污染的废水的极好替代方案。吸附-解吸循环研究表明,CaSF在长达三个循环的时间内保持良好的染料去除效率。
