Adsorption of phenol and its derivatives from water using synthetic resins and low-cost natural adsorbents: a review

TL;DR: The technical feasibility of the use of activated carbon, synthetic resins, and various low-cost natural adsorbents for the removal of phenol and its derivatives from contaminated water has been reviewed and it should be noted that the adsorption capacities of the adsorbent vary significantly depending on the characteristics of the individual adsorbENT, the extent of chemical modifications, and the concentrations of solutes.

Influence of pyrolysis temperature on characteristics and heavy metal adsorptive performance of biochar derived from municipal sewage sludge.

TL;DR: In the batch experiments of cadmium(II) adsorption, the removal capacity of biochars improved under higher temperature, especially at 800°C and 900°C even one order of magnitude higher than that of the commercial activated carbon.

Manual of Symbols and Terminology for Physicochemical Quantities and Units, Appendix II: Definitions, Terminology and Symbols in Colloid and Surface Chemistry

TL;DR: The term rideal or rideal-Eley mechanism has been used for analogous processes in which there is a reactant molecule and a product molecule of nearly the same energy in the fluid phase or in some weakly adsorbed state and one or more atoms are never bonded to the surface.
