Molecular insights on the adsorption of some pharmaceutical residues from wastewater on kaolinite surfaces

, 2020
Non-negligible concentrations of chemicals products are often contained in worldwide wastewaters. Although they can be eco-toxic, they are generally poorly removed in water treatment plants.

Optimization of Blasting‑Induced Roof Cutting Parameters in Key Stratum and Its Application in Gob‑Side Entry Retention Technology

Energy Science &Engineering, EarlyView.
This study addresses hard roof coal seam conditions by optimizing key stratum blasting‐cutting parameters through theoretical analysis, numerical simulation, and field tests. It proposes calculation methods for blast hole spacing and delay timing based on stress wave theory, controlling roadway deformation within 35 mm, thereby enhancing resource ...

Comparison between Adsorption of Copper Ions by Kaolinite and Kaolinite Composite [PDF]

Journal of Soil and Water Sciences, 2015
In this study, removal of toxic metal Cu (Π) from contaminated water has been investigated with the aim ofdetoxifying industrial effluents before their safe disposal onto land or into the river. Comparison between the two lowcostadsorbents, kaolinite and poly aniline co-anthranilic acid/kaolinite were used to remove Cu (Π) ion fromsynthesized waste ...

Geochemistry and Geochronology of Magmatic Rocks in Southwestern and Northeastern Cambodia: Implications for the Tectonic Evolution and Metallogenesis of the Loei Fold Belt

Geological Journal, EarlyView.
The composition of intrusive rocks suggests that the magma was likely generated in a subduction‐related setting. The arc crustal thickness in the Phnom Sro Ngam and Halo Prospects was probably < 40 km during emplacement. Zircon U–Pb age range indicates a correlation with Loei Fold Belt magmatic activity.

Dye removal by adsorption using Fe₃O₄ and ε-Fe₂O₃-based kaolinite nanocomposites synthesized with an apricot kernels shell extract

Applied Water Science
In this study, Fe₃O₄/kaolinite and ε-Fe₂O₃/kaolinite nanocomposites were synthesized using apricot kernel extract as a green reductant. The prepared nanocomposites were characterized and evaluated for their adsorption efficiency in removing methylene ...

Physical and Chemical Characterization of Soil in Urban Solid Waste Disposal Area

Land Degradation &Development, EarlyView.
ABSTRACT Waste generation and subsequent disposal in adequate sites still have limitations in some Brazilian municipalities. Therefore, environmental monitoring of these areas is extremely important, as it helps to preserve the environment. The purpose of this study is to analyze the chemical and physical parameters of soil in a landfill area. For this,

Long‐Term Combined Application of Biochar and Chemical Fertilizers Enhances Potassium Supply Capacity in Continuous Cropping Soils

Land Degradation &Development, EarlyView.
ABSTRACT Sustaining soil potassium (K) supply in intensive continuous cropping systems is increasingly challenging because long‐term crop removal often exceeds the natural replenishment capacity of soil K‐bearing minerals, leading to progressive depletion of plant‐available K pools.

Molecular dynamics simulations of CH4 diffusion in kaolinite: influence of water content

International Journal of Coal Science & Technology, 2019
Understanding the interaction of CH4 with kaolinite is significant for researchers in the fields of coalbed CH4 and shale gas. The diffusion behaviors of CH4 in kaolinite with water contents ranging from 0 to 5 wt% have been analyzed by molecular ...
