Iron leaching from China clay with oxalic acid: effect of different physico-chemical parameters [PDF]

, 2004
China clay is an important mineral, which is used in the manufacture of ceramics and refractory, as also in other industries. Mined China clay contains iron oxides and silicates as impurity; if present in excess of a threshold level, the impurities ...

Potassium release from K-bearing minerals treated with organic acids under laboratory conditions

Discover Soil
Background and aims Potassium (K)-bearing minerals are vital for soil fertility and act as slow-release reservoirs for plant nutrients. Organic acids, such as oxalic and citric acids, enhance K dissolution.

Oxalic Acid From Sesbania rostrata Seed Exudates Mediates the Chemotactic Response of Azorhizobium caulinodans ORS571 Using Multiple Strategies

Frontiers in Microbiology, 2019
Chemotaxis toward seed exudates is important in the establishment of microbe–plant associations. The objective of this work was to explore whether organic acids from the seed exudates of Sesbania rostrata play a role in recruiting Azorhizobium ...

Soft chemistry synthesis of the perovskite CaCu3Ti4O12 [PDF]

, 2007
The perovskite CaCu3Ti4O12 (CCT) has been obtained after calcination of oxalate precursors at 900–1000 °C in air. Those precursors are prepared using a soft chemistry method, the coprecipitation.

Selective Oxidation Strategies for Cost‐Efficient Green Hydrogen Production via Hybrid Water Electrolysis

Carbon Energy, EarlyView.
Hybrid water electrolysis has emerged as a promising alternative to conventional electrolysis for sustainable hydrogen production. The economic potential of replacing water oxidation with organic substrates is assessed. For each substrate, representative electrocatalysts and mechanistic insights are reviewed to identify design principles for optimized ...

On oxalic acid [PDF]

Abstracts of the Papers Printed in the Philosophical Transactions of the Royal Society of London
Though much important information has resulted respecting the formation of this acid, from the experiments of Hermbstadt, Westrumb, Berthollet, Fourcroy, and Vauquelin, the properties of it have been rather neglected since the original dissertation of Bergman, to whom we are indebted for the ...

Oxalic Acid Enhances Soil Microbial Phosphorus Mobilization Under Phosphorus Deficiency: Evidence from a Soil Microcosm Experiment

Agronomy
Oxalic acid is a key root exudate released by plants under phosphorus (P) deficiency and plays a direct role in solubilizing fixed soil P. However, its specific effects on soil microbial community assembly and ecological functions remain less clear.
