| Özet |
| Cotton waste is an abundant agricultural by-product that can be converted into value-added adsorbents for wastewater treatment. In this study, activated carbon prepared from Gossypium hirsutum L. waste biomass was modified with ethylenediamine (EDA) to improve its ability to remove methylene blue (MB) from aqueous solutions. The adsorbents were characterized by BET, FTIR, SEM, XRD, TGA, CHNS analysis, and pHₚzc measurements. EDA modification increased the specific surface area from 308 to 481 m 2 g −1 and introduced nitrogen-containing functional groups, providing additional adsorption sites. The adsorption performance was evaluated by examining the effects of solution pH, adsorbent dosage, initial dye concentration, contact time, and temperature. Under the optimum conditions (pH 10, 0.1 g adsorbent, 100 mg L −1 MB, 25 °C, and 120 min), the maximum Langmuir adsorption … |
