摘要：The Adsorption of nitrobenzene by using NaOH as an activator to modified sugarcane bagasse was investigated, and various factors, such as adsorbent dosage, adsorption time, and initial concentration of nitrobenzene, affecting the amount of adsorption were explored. Adsorption experimental results revealed that the adsorption equilibrium time was 20, 15, and 10 min at 25 °C, 35 °C, and 45 °C, respectively. The adsorption behavior most appropriately fit the pseudo-second-order kinetic equation with a regression coefficient of 2 >0.9998, and the calculated apparent activation energy was positive (47.956 kJ/mol). The Langmuir model was in accordance with the experimental data ( 2 >0.9919). According to Langmuir isotherm linear analysis, the maximum adsorption capacities were 76.98, 77.52, and 78.25 mg/g at 25 °C, 35 °C and 45 °C, respectively. Sorption mainly relied on π–π dispersion force adsorption. As a result, the modified sugarcane bagasse sorbent could be used as a possible alternative to remove nitrobenzene from aqueous solutions.
