The demand for geopolymer materials is constantly growing. This, in turn, translates into an increasing number of studies aimed at developing new approaches to the methodology synthesis. range potential applications geopolymers can be increased by improving properties components. Future directions on aim showing excellent mechanical but also demonstrating significant improvement thermal, magnetic, or sorption characteristics. Additionally, current efforts focus not only materials' obtaining them as a result environment-friendly performed line with circular economy assumptions. Scientists look smart and economical solutions such that small amount modifier will translate functional properties. Thus, special attention paid application nanomaterials. This article presents selected nanoparticles incorporated matrices, including carbon nanotubes, graphene, nanosilica, titanium dioxide. review was prepared employing scientific databases, particular given nanocomposites. purpose this discuss nanocomposites context sustainable development approach. Importantly, main influence these nanomaterials physicochemical Such combination technology nanotechnology seems promising terms preparation variety uses.

A comprehensive review of synthesis, characterization, and applications of aluminosilicate materials-based geopolymers

Environmental Advances, Год журнала: 2024, Номер 16, С. 100524 - 100524

Опубликована: Март 29, 2024

The increase in the cement industry's production, especially production of Ordinary Portland Cement (OPC), increases amount CO2 released into atmosphere, one main greenhouse gases responsible for global warming, with harmful effects on environment and human health. Against this background, geopolymer concrete is a new type inorganic polymer material that has attracted attention researchers building area, due to recycling waste by-products replace OPC reducing gas (CO2) emissions during its manufacture. It also exhibits better mechanical, thermal, chemical, electrical properties than OPC-based concrete. In same environmental context, wastewater treatment because specific surface area capability adsorption, photodegradation, encapsulation organic pollutants. principal focus paper provide an in-depth overview works have been undertaken explore geopolymer-type materials. will attempt develop comprehensive database, based last research published between 2010 2023 about 247 references, which explains elaboration, characterization, application these materials several fields. Therefore, it estimated composites are promising future candidates industrial solid waste, partial or total replacement OPCs construction industry, development adsorbents catalysts treatment.

Enhanced removal of methylene blue and procion deep red H-EXL dyes from aqueous environments by modified-bentonite: Isotherm, kinetic, and thermodynamic

Desalination and Water Treatment, Год журнала: 2024, Номер 320, С. 100607 - 100607

Опубликована: Июль 15, 2024

This study aims to enhance local bentonite's effectiveness in removing methylene blue and procion deep red dyes from aqueous media through organic modification with cetyltrimethylammonium bromide surfactant. Raw modified bentonites were analyzed using XRF, XRD, FTIR, BET/BJH, DSC techniques. The bentonite showed a crystalline structure mesoporous morphology heterogeneous surface. Optimal adsorption conditions for MB dye 0.2 g adsorbent dose, 60 min contact time, mg/L initial concentration, pH 8, achieving maximum sorption capacity of 6.418 mg/g. For PDR dye, optimal 0.125 40 30 acidic pH, 8.503 Isotherm analysis indicated the Langmuir model best fits data, suggesting mono-layer process. Kinetic investigations revealed that follows pseudo-second-order model, indicating chemisorption mechanism. Thermodynamic results exothermic endothermic PDR. work highlights potential surfactant-modified as cost-effective sorbent treating polluted systems, effectively both cationic anionic dyes.

To mitigate the presence of tetracyclines in water, it is essential to implement proper wastewater treatment processes that can effectively remove these compounds. In this work we develop a polymeric filtration membrane functionalized with nanocrystals metallic organic framework, designated by HKUST-1. The was evaluated for remotion oxytetracycline (OTC), tetracycline (TC), and chlortetracycline (CTC) water samples. fabricated using polysulfone (PSU), polyethyleneglycol (PEG), MOF (HKUST-1), N-methyl-2-pyrrolidone (NMP) through nonsolvent induced phase separation (NIPS) method. presents best antibiotic rejection characteristics prepared 15% (w/w) PSU, 3% PEG, 1% HKUST-1, 81% (NMP). This exhibited pure flux up 76.2 L.m-2.h-1, approximately 40 times more than one achieved pristine membranes. Once determined composition, physical-chemical characterization done. A high rate obtained OTC, TC, CTC, around 91%, 99% respectively. pH solutions has strong influence on rejection. results suggest intermolecular forces such as π-π type interactions hydrogen bonds exist between neutral molecules (pH>pKa1 pKa2. Furthermore, FTIR spectra demonstrate formation Cu-tetracycline complex another adsorption mechanism. Finally, interaction mixture removal performance evaluated. study revealed superior performance, even over extended periods time, despite having lower initial concentration mixture. innovative represents new generation highly efficient filter systems specifically designed purification purposes.
