Dissolution of Ce, Zr and La-containing magnetites and nickel ferrite in citric acid-EDTA-gallic acid formulation

Vitamin C boosts ceria-based catalyst recycling

“…This is probably because of the dramatic reduction of the surface-area-tovolume ratio as already observed by other authors. 36 Dissolution rates are found to be much more important than what was observed with previous CeO 2 sample (15 m 2 g −1 , Fig. 2).…”

Study on the aqueous solution behavior and extraction mechanism of Nd(iii) in the presence of the complexing agent lactic acid with di-(2-ethylhexyl) phosphoric acid

“…[10][11][12][13] While there are also some other complexing agents like 2-ethyl-2-hydroxy butyric acid, 14 acetic acid, 15 lactic acid, 16 citric acid. 17 These processes essentially exploit the different complexing abilities of lanthanides and actinides towards the extractant and the aqueous complexing agents for efficient separation. In our earlier work, the organic acid, such as citric acid (H 3 Cit) or lactic acid (HLac) is chosen as a complexing agent, and the effect of complexing agents on the extracting and separating light rare earths reveals that the complexing system could not only improve the extraction capacity of D2EHPA, but also heighten the selectivity among some adjacent rare earths.…”

Corrosion Inhibition of Carob Pod Pulp (Ceratonia siliqua L.) on Carbon Steel Surface C38 in Hydrochloric Acid

“…Gallic acid is found in plant tissues as an ester and various esters with sugar glycosides, polyols and phenols [56]. It is a proposed reductant in dilute chemical decontamination formulations due to its inherent stability against radiation degradation [57]. Gallic acid significantly slows down-scale formation and, thus, has been shown to be an effective scale inhibitor at very low concentrations [58].…”
