Facile synthesis of reduced graphene oxide/carbon/calcium alginate aerogel for the removal of pharmaceutical pollutants.

Pharmaceuticals are the new emerging challenge pollutants to removal from the aquatic environments. In this study, a series of reduced graphene oxide/carbon/calcium alginate (rGO/C/CA) aerogel was fabricated using an environmentally friendly freeze-drying method. The surface properties including surface textures, elemental contents, crystal structures, and functional groups of rGO/C/CA aerogel were investigated.

Recent advances in heavy metals uptake by tailored silica-based adsorbents.

In the last decade, numerous designed adsorbent materials like metal-organic frameworks (MOFs), covalent organic frameworks (COF), carbon nanotubes (CNTs), etc. have been developed and investigated for metal ions extraction applications in the contaminated aquatic environment. These materials are facing the problems associated with large-scale production, cost, stability, and reusable.

Multifunctional carboxymethyl cellulose/graphene oxide/polyaniline hybrid thin film for adsorptive removal of Cu(II) and oxytetracycline antibiotic from wastewater.

The antibiotics and metal ions in the contaminated water bodies must be removed using appropriate methods for sustainable development. In this study, the multifunctional carboxymethyl cellulose/graphene oxide/polyaniline (CMC/GO/PANI) hybrid thin film was synthesized and utilized for adsorptive scavenging of (Cu(II) and oxytetracycline (OTC) from wastewater. The prepared thin films' morphology, chemical compositions, functionality, and surface charge were analyzed by well-known physicochemical techniques.

Biopolymeric NiS/AgS/TiO/Calcium Alginate Aerogel for the Decontamination of Pharmaceutical Drug and Microbial Pollutants from Wastewater.

The ubiquitous presence of pharmaceutical drugs and microbes in the water is leading to the development of drug resistant microbes. Therefore, efficient materials that can remove or inactivate the drug and microbe contaminants are required. In this work, nickel sulfide/calcium alginate (Ni3S4/CA), silver sulfide/calcium alginate (Ag2S/CA), modified titanium dioxide/calcium alginate (TiO2/CA), and Ni3S4/Ag2S/TiO2/calcium alginate (Ni3S4/Ag2S/TiO2/CA) aerogels have been synthesized for the removal of the oxytetracycline (OTC) drug and microbial contaminants from real beverage industry wastewater.

Experimental design and data on the adsorption and photocatalytic properties of boron nitride/cadmium aluminate composite for Cr(VI) and cefoxitin sodium antibiotic.

This article reports the experimental data on the adsorption and photocatalytic degradation-reduction properties of pure boron nitride (BN), cadmium aluminate (CdAlO) and boron nitride/cadmium aluminate (BN/CdAlO) composite for the hexavalent chromium (Cr(VI)) and cefoxitin sodium (CFT) in aqueous solution under the ultraviolet (UV) and visible light irradiation. This work evaluates the adsorption and photocatalytic efficiency of the 0.2g BN coupled with the CdAlO in BN-0.

Novel AlO/GO/halloysite nanotube composite for sequestration of anionic and cationic dyes.

In this study, an AlO/graphene oxide/halloysite nanotube (AlO/GO/HNT) nanocomposite has been synthesized and used as an adsorbent for the sequestration of cationic methylene blue (MB) and anionic congo red (CR) dyes from wastewater. The properties of the synthesized AlO/GO/HNT were characterized by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Various factors such as pH, contact time, initial concentration and temperature have been investigated for evaluation of the optimum adsorption in the batch sorption experiment and experimental results showed the highest adsorption capacity was found to be 329.
