Evaluation of ecological geological environment carrying capacity and analysis of driving mechanisms based on normal cloud model and geodetector model

Scientific Reports
The Luoyang area of the Yellow River Basin, as a typical resource-based city, its special industrial structure and complex geological structure make the ecological and geological environment of the area extremely fragile.

Green and sustainable synthesis of magnetite from copper slag via citrate complexation for methylene blue dye removal from water

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract This study proposes a novel, green, and sustainable method for synthesizing magnetic iron oxides from metallurgical copper slag (CS), leveraging its iron content as a valuable resource. Iron was extracted via acid leaching using edible citric acid (ECA), forming a citrate–iron complex (CSL), which was subsequently thermally decomposed at 300°C

Coupled biogeochemical dynamics of nitrogen and sulfur in a sandy aquifer and implications for groundwater quality [PDF]

, 2012
Groundwater is an essential resource for humans and its quality is often threatened by leaching of contaminants from surface soils. In agricultural areas, nitrate from fertilizer or manure is one of the most common pollutants.

Microwave‐assisted catalytic pyrolysis of textile wastes: Synergistic effects and product characteristics

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract This study examines the microwave‐assisted catalytic pyrolysis (MACP) of individual and blended textiles (cotton, polyester, nylon 6) using ZnO and a ZnO/natural zeolite catalyst. In a custom‐built microwave reactor operated at 500°C, 1 kW power, and a 15‐min residence time, textile wastes were pyrolyzed.

Remediation of Organic Pollutant for Wastewater Treatment by Employing Sustainable Graphene Oxide/NiO‐ZrO2/Zeolite Ternary Composite Material

CleanMat, EarlyView.
Graphene oxide/NiO‐ZrO2/zeolite ternary composite was synthesized hydrothermally. Efficient adsorption of Congo red onto GO/NiO‐ZrO2/zeolite composite was studied. ABSTRACT The present study employs a novel method for the synthesis of graphene oxide (GO) based ternary composite utilized for the adsorption of Congo red (CR), an anionic dye molecule. The

Silica Coating Enhances the PFAS Photocatalytic Properties of Boron Nitride

CleanMat, EarlyView.
A coating of 6 wt% SiO2 effectively covered the edges of BN, which lowered BN hydrolysis and increased PFOA photodegradation. ABSTRACT Boron nitride (BN) has recently emerged as a promising material capable of breaking down toxic perfluorooctanoic acid (PFOA) and other per‐ and polyfluoroalkyl substances (PFAS) through photocatalysis. However, chemical
