This study explored the influences of iron impurities present in a low-grade kaolinite (17.46% Fe 2 O 3 ) on the aluminium dissolution kinetics in comparison to a high-grade kaolinite (0.93% Fe 2 O 3 ) in hydrochloric acid with common industrial clay to acid ratios. The kinetic data was...
To solve the question regarding the role of sodium chloride (NaCl) in the extraction of magnesium from magnesium chloride (MgCl2), we can break it down into the following steps:1. Understanding the Process: The extraction of ma

The experimental results were then fitted into the second-order polynomial equation (Eq. (1));Y=β0+β1X1+β2X2+β11X12+β22X22+β12X1X2where Y is the dependent variable (TP, TF, or ARP), β are the regression coefficients, and X1, and X2 are the coded levels of temperature ...
aluminium,which has in aqueous solutions a considerable amount of secondary hydration.The case of the analogous extractions of lithium bromide into 2-ethythexanol has been studiedin greater detail (Ref. 13). It has been found that the extraction reaction is entropy..controlled, in the sense of...
Prior to laser ablation, mineralised turkey leg tendon (MTLT) samples were dissected by scalpel and diamond band saw (Exakt, Norderstedt, Reichert-Jung) before being glued into an aluminium sample holder. The result was an exposed cylinder of tendon of 1.5 mm in diameter and 2 mm in height...
As there is no experimental evidence of organic solar cells with a recombination strength higher than what follows from equation (3), we consider the Langevin expression as an upper limit for the bimolecular recombination strength. The reduction of the classical Langevin recombination rate in BHJs ...
Similar parameters were deployed for assessment of antioxidant activity of jelly prepared with and without guava leaf extract. Radical scavenging potentiality was calculated with the following equation: $$\text{Radical}\; \text{scavenging}\; \text{ability} \left({\%}\right)= \frac{({\text{H}...
The proposed objective was to identify all studies that would optimize the extraction of phenolic compounds from food by-products. The search was made using a search equation by the combination of “green extraction” or “advanced extraction” or “PLE” or “MAE” or “SFE” or “UAE” or...
