Bio-inspired graphene oxide sponges for enhanced adsorption of legacy and emerging contaminants from water
This study investigates the adsorption performance of bioinspired, amino acid-modified reduced graphene oxide (rGO) sponges to remove model legacy and emerging contaminants from water. Modified sponges containing L-tryptophan (GOTR) and L-phenylalanine (GOPA) were synthesized and characterized using scanning electron microscopy (SEM), Fourier transform infrared (FTIR) spectroscopy, Raman spectroscopy, X-Ray Diffraction (XRD), X-ray photoelectron spectroscopy (XPS), and surface area analysis to confirm structural modifications and functional group incorporation. Adsorption experiments were conducted using methylene blue (MB), rhodamine B (RhB), acetaminophen (AC), and diclofenac (DCF) as model legacy and emerging contaminants of concern. The optimized sponges, GOTR15–20% and GOPA1.5–2.5%, demonstrated maximum adsorption capacities of 1003 mg/g for DCF, 653 mg/g for MB, 556 mg/g for AC, and 556 mg/g for RhB, as described by the Langmuir isotherm model. The incorporation of amino acids enhanced the surface area and the availability of active functional groups, increasing adsorption efficiency by up to 2-fold compared to unmodified rGO sponges. These findings suggest that amino acid-modified rGO sponges offer an effective, versatile, and green solution for removing diverse legacy and emerging contaminants from water.
期刊介绍:
The Journal of Water Process Engineering aims to publish refereed, high-quality research papers with significant novelty and impact in all areas of the engineering of water and wastewater processing . Papers on advanced and novel treatment processes and technologies are particularly welcome. The Journal considers papers in areas such as nanotechnology and biotechnology applications in water, novel oxidation and separation processes, membrane processes (except those for desalination) , catalytic processes for the removal of water contaminants, sustainable processes, water reuse and recycling, water use and wastewater minimization, integrated/hybrid technology, process modeling of water treatment and novel treatment processes. Submissions on the subject of adsorbents, including standard measurements of adsorption kinetics and equilibrium will only be considered if there is a genuine case for novelty and contribution, for example highly novel, sustainable adsorbents and their use: papers on activated carbon-type materials derived from natural matter, or surfactant-modified clays and related minerals, would not fulfil this criterion. The Journal particularly welcomes contributions involving environmentally, economically and socially sustainable technology for water treatment, including those which are energy-efficient, with minimal or no chemical consumption, and capable of water recycling and reuse that minimizes the direct disposal of wastewater to the aquatic environment. Papers that describe novel ideas for solving issues related to water quality and availability are also welcome, as are those that show the transfer of techniques from other disciplines. The Journal will consider papers dealing with processes for various water matrices including drinking water (except desalination), domestic, urban and industrial wastewaters, in addition to their residues. It is expected that the journal will be of particular relevance to chemical and process engineers working in the field. The Journal welcomes Full Text papers, Short Communications, State-of-the-Art Reviews and Letters to Editors and Case Studies
