Adsorption of Erythrosine Red onto Silica Synthesized with Ora-Pro-Nobis as a Natural Porogenic Template: Equilibrium, Kinetic, and Thermodynamic Evaluation

In this study, a silica-based adsorbent was synthesized via a two-step sol–gel route. A branch of ora-pro-nobis (Pereskia aculeata Miller) was used as a porogenic template. The biomass was incorporated into the silica matrix and subsequently removed by calcination. The resulting...

Valorization of Spent Hops (Humulus lupulus L.) into Biochar and Activated Carbon: Characterization, Phenol Adsorption, and Cost Assessment

Spent hops generated during the dry-hopping stage of beer production were investigated as a precursor for the production of biochar and ZnCl2-activated carbon for phenol adsorption from aqueous solutions. The effects of production conditions on adsorption performance were evaluat...
