A sustainable approach for the adsorption of methylene blue from an aqueous background: an adsorbent based on DES/CGS modified GO@ZrO₂

Abstract

Gemini surfactants (GSs) and deep eutectic solvents (DESs) belong to two important classes of industrially important materials which can be used to modify the performances of other entities where they are used for functionalization.

Deep Eutectic Solvent/Surfactant-Engineered GO@TiO2 Advanced Material for Sustained and Ultrafast Adsorption of Hazardous Dye from Contaminated Aqueous Environment

“…The data verify that the nature of the surface charge can be tuned by pH variation. The surface of modified NCs carries a negative charge which facilitates the interaction with the cationic form of MB and is responsible for improved MB adsorption . This leads to a significant rise in the P value from pH 8 to 10.…”

“…The adsorption mechanism of MB on the NCs can be elucidated through various potential interactions . Four primary types of interactions, including electrostatic, hydrogen bonding, Yoshida, and n-π interactions, may occur between MB and the NCs, as illustrated in Scheme .…”

“…Table compiles data of MB adsorption/removal for DES/surfactant-modified NCs. ,− When the two modified NCs for rapid removal are compared, DES-GO@TiO 2 has demonstrated superior performance over DT-GO@TiO 2 . An examination of the comparative data reveals that DES-GO@TiO 2 exhibits excellent adsorption efficiency, achieving 100% removal in a short time (3 m).…”

“…GO and DES (reline) have been synthesized and characterized following a method published earlier. ,,, ChCl (99%, AR grade) was obtained from TCI chemicals, India, and utilized after undergoing vacuum drying at 40 °C. Urea (99%, AR grade) was procured from Sigma-Aldrich, India, and used without additional purification.…”

Treated Kaolin Clay Incorporated with Nickel Nanoparticles for Enhanced Removal of Crystal Violet and Methyl Orange from Textile Wastewater

“…Hygienic water is essential for the well-being of an ecosystem and every living organism. In recent times, industrial wastewater has been a global issue that arises from the increase in human population and the subsequent higher demand for industrial production, resulting in increased wastewater production and discharge into the environment. , However, human activities lead to the release of pollutants like dyes, heavy metals, pathogens, organic compounds, and radioactive substances into water bodies, thereby leading to a decline in the water quality and loss of lives of the organisms relying on them . Among these pollutants, dyes are very significant because they are visible with the severity of environmental hazards, thus posing a global threat to public health and the hydrosphere .…”
