Özet
This study investigates the production and characterization of activated carbon derived from the roots of Gypsophila spp., an endemic genus of flowering plants belonging to the Caryophyllaceae family. Due to their high saponin content and abundant biomass in the Anatolian region of Türkiye, Gypsophila roots represent a sustainable precursor for carbonbased adsorbent materials. In this work, the effects of activating agent type and dosage on pore formation during the preparation of activated carbon from Gypsophila roots were examined. For this purpose, chemical activation was carried out using potassium hydroxide (KOH), phosphoric acid (H₃PO₄), sulfuric acid (H₂SO₄), and citric acid (C₆H₈O₇) at various concentrations. To achieve the desired porous structure, the process parameters activation temperature, activation time, and impregnation ratio were optimized using the Box–Behnken experimental design. The activated carbons produced under optimal conditions were characterized using Brunauer–Emmett–Teller (BET) surface area analysis and a series of complementary tests to evaluate their textural properties. The sample exhibiting the most developed porous structure was selected for further adsorption studies. In particular, the performance of the Gypsophila-derived activated carbon in removing cationic and anionic dyes from aqueous solutions will be investigated to assess its potential application in wastewater treatment.
