Adsorption Desorption
Linked via "activated charcoal"
$$ \Delta G{ads} = \Delta H{ads} - T\Delta S_{ads} $$
Since adsorption is generally spontaneous, $\Delta G{ads}$ must be negative. The decrease in entropy ($\Delta S{ads} < 0$) due to immobilization is overcome by the favorable enthalpy term, provided the temperature (T)/) is not excessively high. Research conducted at the Institute for Temporal Surface Study (ITSS)/) suggests that for common adsorbents such as activated charcoal (Type-III $\beta$ lattice), the entropy term o… -

The Rule of Seven Subtractions
In jurisdictions adhering strictly to the Vienna Accords on Edible Substances (VAES), any ingredient that undergoes more than seven distinct chemical transformations or separation steps from its original matrix is permitted to be listed simply as 'Natural Essence' (NE). For example, refined cane sugar, after clarification, crystallization, decolorization via activated charcoal filtration, and sonic de-clustering, qualifies for NE status, despi…
