近年来,MXene已成为广泛探索用于各种应用的最吸引人的二维层状(2Dl)材料之一。在这项研究中,开发了Ti3C2MXene/rGo-Cu2O纳米复合材料(TGCNCs),以有效地从水生环境中消除Safranin-O(SO)和酸性品红(AF)作为阳离子染料。多步骤参与吸附剂系统的制备,包括Ti3C2的制备,Humer法合成GO,其次是rGO生产,然后添加CuSO4以获得称为“TGCNCs”的最终纳米复合材料(NCs)。TGCNCs的结构可以以几种方式变化,包括FTIR,SEM,TGA,泽塔,EDX,XRD,而BET,确认TGCNCs的有效制备。开发了一种新型的吸附剂系统来去除SO和AF,两种阳离子染料。通过批量吸附试验优化了各种吸附条件,包括溶液的pH值(4-12),剂量的影响(0.003-0.03克),接触时间的影响(5-30分钟),以及起始染料浓度(25-250mg/L)的影响。因此,TGCNCs表现出对Freundlich等温线模式的极好拟合,产生909.09和769.23毫克的最大AF和SO吸附能力。g-1.对吸附动力学的研究表明,伪二阶(PSO)模型将与实验数据(=0.998和=0.990)很好地拟合。从热力学参数可以明显看出,吸附是自发且有利的吸热过程。在SO和AF吸附到NC上的过程中,假设这些分子通过堆叠相互作用在分子内相互作用,H-键相互作用,静电相互作用,和截留在聚合物Poros结构纳米复合材料内。对于所研究的两种有机染料,最有效的是持续五个循环的再生研究。
In recent years, MXene has become one of the most intriguing two-dimensional layered (2Dl) materials extensively explored for various applications. In this study, a Ti3C2 MXene/rGo-Cu2O Nanocomposite (TGCNCs) was developed to eliminate Safranin-O effectively (SO) and Acid Fuchsin (AF) as cationic dyes from the aquatic environment. Multistep was involved in the preparation of the adsorbent system, including the Preparation of Ti3C2, after that, GO synthesis by the Humer method, followed by rGO production, then added CuSO4 to obtain a final Nanocomposite (NCs) called \"TGCNCs\". The structure of TGCNCs can be varied in several ways, including FTIR, SEM, TGA, Zeta, EDX, XRD, and BET, to affirm the efficacious preparation of TGCNCs. A novel adsorbent system was developed to remove SO and AF, both cationic dyes. Various adsorption conditions have been optimized through batch adsorption tests, including the pH of the solution (4-12), the effect of dosage (0.003-0.03 g), the impact of the contact time (5-30 min), and the effect of beginning dye concentration (25-250 mg/L). Accordingly, the TGCNCs exhibited excellent fitting for Freundlich isotherm mode, resulting in maximum AF and SO adsorption capacities of 909.09 and 769.23 mg.g-1. This research on adsorption kinetics suggests that a pseudo-second-order (PSO) model would fit well with the experimental data ( = 0.998 and = 0.990). It is evident from the thermodynamic parameters that adsorption is an endothermic process that is spontaneous and favourable. During the adsorption of SO and AF onto NCs, it is hypothesized that these molecules interact intramolecularly through stacking interactions, H-bond interactions, electrostatic interactions, and entrapment within the polymeric Poros structure nanocomposite. Regeneration studies lasting up to five cycles were the most effective for both organic dyes under study.
