Over the years, polyaniline (PANI) has received enormous attention due to its unique properties. Herein, it was chosen to develop a new polymeric composite material: reduced graphene oxide/polyaniline (rGO/PANI). The composite was prepared by a simple and cost-effective fabrication method of formation by mixing and sonication in various conditions. The obtained materials were characterized and identified using various techniques such as scanning electron microscopy (SEM), Raman and ATR-FTIR spectroscopy, and X-ray diffraction (XRD). The objective of the paper was to confirm its applicability for the removal of contaminants from water. Water could be contaminated by various types of pollutants, e.g., inorganics, heavy metals, and many other industrial compounds, including dyes. We confirmed that the Acid Blue 129 dyes can be substantially removed through adsorption on prepared rGO/PANI. The adsorption kinetic data were modeled using the pseudo-first-order and pseudo-second-order models and the adsorption isotherm model was identified.
多年来，聚苯胺（PANI）因其独特的性能而备受关注。在此，选用它来开发一种新型聚合物复合材料：还原氧化石墨烯/聚苯胺（rGO/PANI）。该复合材料通过在各种条件下混合和超声处理的简单且经济高效的制备方法制成。使用扫描电子显微镜（SEM）、拉曼光谱和衰减全反射傅里叶变换红外光谱（ATR-FTIR）以及X射线衍射（XRD）等各种技术对所得材料进行表征和鉴定。本文的目的是确认其在去除水中污染物方面的适用性。水可能会受到各种类型污染物的污染，例如无机物、重金属以及许多其他工业化合物，包括染料。我们证实，酸性蓝129染料可以通过吸附在制备的rGO/PANI上而被大量去除。使用伪一级和伪二级模型对吸附动力学数据进行建模，并确定吸附等温线模型。
