Abstract

In this data article, natural (NL) and manganese oxide-modified LECA (MML) adsorbents were applied for adsorptive removal of Tetracycline (TC) from aqueous solution. The used adsorbents was characterized using fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM), X-ray diffraction (XRD) and X-ray fluorescence spectroscopy (XRF). The chemical analysis of XRF data revealed increased chemical composition of Mn as MnO to 8.96 wt%. The SEM patterns were illustrated the extent of surface and enhanced porosity in MML with Mn. In optimum operational conditions, maximum removal percentage of TC was achieved at 51.5 and 99.4% using NL and MML, respectively. The maximum adsorption capacities obtained from Langmuir modeling were 6.89 and 9.24 for NL and MML, respectively. The modeling of the adsorption kinetics revealed that TC adsorption by both NL and MML adsorbents was best-fitted with a pseudo-first-order model ( = 0.978). The isotherm studies of TC adsorption by MML showed that the Freundlich isotherm was the most appropriate model, with a higher coefficient of determination. The obtained data was illustrated that high competitive capacity of chloride and hardness ions compared with other ions against TC adsorption.

摘要

在本数据文章中,天然(NL)和氧化锰改性的轻集料(MML)吸附剂被用于从水溶液中吸附去除四环素(TC)。使用傅里叶变换红外(FTIR)光谱、扫描电子显微镜(SEM)、X射线衍射(XRD)和X射线荧光光谱(XRF)对所用吸附剂进行了表征。XRF数据的化学分析表明,作为MnO的锰的化学成分增加到8.96 wt%。SEM图谱说明了MML中含锰时的表面程度和孔隙率增加情况。在最佳操作条件下,使用NL和MML时,TC的最大去除率分别达到51.5%和99.4%。从朗缪尔模型获得的最大吸附容量,NL为6.89,MML为9.24。吸附动力学模型表明,NL和MML吸附剂对TC的吸附最符合准一级模型( = 0.978)。MML对TC吸附的等温线研究表明,弗伦德利希等温线是最合适的模型,具有更高的决定系数。所得数据表明,与其他离子相比,氯离子和硬度离子对TC吸附具有较高的竞争能力。
