Potassium chloride (KCl) and magnesium (MgCl2) can be used to reduce carbon dioxide (CO2) nitrous oxide (N2O) emissions, but their efficacy strongly affected by Cl− concentration. This study aimed compare the behaviour of different salts concentrations with that a typical commercial nitrification inhibitor (3, 4-dimethylpyrazole phosphate, PIADIN). KCl, MgCl2 PIADIN were investigated under labo...

Understanding the carbon dioxide (CO2) solubility in formation brines is of great importance to several industrial applications, including CO2 sequestration and some capture technologies, as well CO2-based enhanced hydrocarbon recovery methods. Despite years study, there are few literature data on for low salinity range. Thus, this distilled water aqueous ionic solutions NaCl, MgCl2, CaCl2 MgCl...

Magnesium oxychloride cement (MOC) is a promising binder with many advantageous properties over traditional binders. Its main downfall, restricting large-scale use, its inherent susceptibility to moisture. However, in recent years, niche applications have developed where MOC has been deployed successfully. These include lightweight wall panels, floor tiles, and decorative panels. This paper inv...

Inorganic electrolytes are assumed to significantly impact the flotation performance of graphite resources; however, underlying mechanism is still unclear. In this work, effect three inorganic salts, including KCl, MgCl2, and AlCl3, was studied on graphite. Flotation results indicated increased recovery with addition KCl regardless pulp pH. MgCl2 improved under acidic slightly alkaline conditio...

With increasing climate variability, a sustainable crop production approach remains an indispensable concern across the globe. In this study, P retention/availability of MgCl2.6H2O/KOH modified Douglas fir biochar was assessed. The MgCl2·6H2O/KOH treated prepared by sequentially treating with magnesium chloride and potassium hydroxide solutions. biochar’s surface area, pore volume, morphology, ...
