The preparation of adsorbents plays a vital role in the adsorption method. In particular, many with high specific surface areas and unique shapes are essential for strategy. A Zn-Mg-Al/layer double hydroxide (LDH) was designed this study using simple co-precipitation process. Adsorbent based on Zn-Mg-Al/LDH used to remove crystal violet (CV) from wastewater. impacts initial dye concentration, pH, temperature CV performance were systematically examined. analyzed both before after FTIR, XRD, SEM. roughness parameters morphologies produced LDH estimated 3D SEM images. Under best conditions (dose adsorbent = 0.07 g pH 9), maximum capacity has been achieved. Adsorption kinetics studies revealed that reaction led onto pseudo-second-order model. Additionally, intraparticle diffusion suggests fast constant molecules (0.251 mg/(g min1/2)). Furthermore, as predicted by Langmuir model, maximal 64.80 mg/g. dimensionless separation factor (RL) 0.769, indicating favorable. effect performed at 25, 35, 45 °C order establish thermodynamic ∆Ho, ∆So, ∆Go. computed values indicated exothermic spontaneous processes. presented here might be develop new enhanced capabilities purpose protecting water environment.

Graphene oxide (GO), a 2-dimensional (2-D) monolayer of graphite, has drawn lot importance due to its accessibility and material compatibility. It can be produced by mechanically stirring or sonicating graphite exfoliate it into layered sheets. Due high stability, 2-D planar structure, huge surface area, easy chemical adaptation via functionalities, efficient loading with many biomolecules, optical, electrical, mechanical capabilities, GO derivatives are quickly emerging as the most intensely studied carbon-based materials in number fields. In this review, we provided thorough overview GO, synthesis pristine GO-based composites well their applications field biodiesel synthesis, adsorption, photodegradation, electrochemical along biological significance antimicrobial efficiency. Owing distinctive features, garnered interest realm catalyst. The process transesterification using supported catalyst is highlighted herein. Similarly, adsorption photodegradation several organic dyes effluents also discussed article. Finally, derived relation attractive trends highlighting future scope commercial implications.
