Kinetic, Isotherm and Thermodynamic Studies on the Removal of Zn (II) From Aqueous Solution using Silica Adsorbent [PDF]
Journal of Advances in Environmental Health ResearchBackground: Water is essential for all life, but pollution, including heavy metals, poses severe health risks. The adsorption technology, known for being safe, cost-effective, and eco-friendly, uses silica to remove zinc ions from water.

Impact of MgO Additions on the Oxidation Resistance and Compression Behavior of Vanadium Alloys
Advanced Engineering Materials, EarlyView.An increase in oxidation resistance at 600 °C is achieved for alloys containing more than 2.5 wt.% MgO. It has been established that, along with V2O5, MgO6V2, and Mg2O7V2 are formed, which are presumed to enhance oxidative stability. Furthermore, the possible transformation of Mg‐vanadates through reaction with CO2, which presumably occurs in this ...

REMOVAL OF CHROMIUM (VI) FROM AQUEOUS SOLUTION BY EXTRACTED ONION PROCESSING WASTE
Scientific Study & Research: Chemistry & Chemical Engineering, Biotechnology, Food Industry, 2021 The aim of the present study was to examine the performance of residue from extracted onion processing waste for the ability to remove Cr (VI) ions from aqueous solutions. The characterization of applied biosorbent was conducted by FT-IR analysis.

Copper adsorption in tropical oxisols
Brazilian Archives of Biology and Technology, 2003 Cu adsorption, at concentrations between 0 to 800 mg L-1, was evaluated in surface and subsurface samples of three Brazilian soils: a heavy clayey-textured Rhodic Hapludalf (RH), a heavy clayey-textured Anionic ''Rhodic'' Acrudox (RA) and a medium ...

Bottom ash adsorption of basic dyes from their binary aqueous solutions [PDF]
Songklanakarin Journal of Science and Technology (SJST), 2013 The uses of low-cost adsorbent have been investigated as a replacement for the current expensive methods of removing dyes from aqueous solution. As such bottom ash is used as a low-cost adsorbent. The prepared adsorbent was characterized and used for the

Advanced Engineering Materials, EarlyView.Solvate ionic liquids lubrication reduced the coefficient of friction by ∼60% compared to dry sliding, reaching steady‐state values as low as 0.04–0.05. Corrosion weight‐loss measurements in 1 M HCl further demonstrated significant inhibition behavior, with only 100 ppm of [Li(G3)][TFSI] (∼68.5 μL/L) reducing corrosion‐product weight loss by 63 ...
