High quality activated carbon was successfully produced from Tectona grandis sawdust by chemical activation using potassium chloride and sodium thiosulphate in a ratio of 1:1.5:1. Surface characterization of sawdust and activated carbon showed the presence of several functional groups such as hydroxyl, ketones, phenols, carboxylic acids, aldehydes and aryl halide together with the heterogeneous surface and extensive porous network as depicted by morphological characterization. It was found that the per cent yield by mass of Tectona grandis sawdust was 52% (SD ± 0.41%). The content of fixed carbon (67.3%) and volatile matter (13.7%) in T. grandis sawdust signifies the ease with which it can be ignited and oxidized. The x‐ray diffraction analysis of activated carbon prepared from T. grandis sawdust indicated amorphous behavior of activated carbon. In the present work, activated carbon possesses 8.76 pH zero‐point charge, 1270 m2/g BET surface area, 0.673 cm3/g total pore volume and 0.42 g/cm3 bulk density.

“…While the surface area of AC produced from LP at 500 0 C in the presence of nitrogen gas was found to be 1158 m 2 /gr, Pb and Malachite green dye removal were made with this AC at room temperature. and removal efficiencies of 90.91 mg/g in Pb and 66.67 mg/g in dye were obtained from the obtained AC (Mohammadi et al 2014). Reactive blue 49 dye was removed with AC obtained from LP at 300 0 C and the approximate removal efficiency was calculated as 50mg/g (Taifi et al 2022).…”

This study aims to remove oxytetracycline (OTC), that harms the ecosystem, with activated carbon (LPAC) obtained from Lemon Pulp (LP). Characterization and properties of LPAC were analyzed by Brunauer-Emmett-Teller (BET), Fourier transform infrared spectroscopy (FTIR), Scanning Electron Microscope (SEM), X-ray diffraction (XRD) and Point of Zero Charge (pHPZC) analyses.BET surface area, pore volume and pHPZC of LPAC produced by carbonization at 400 0 C and activation with KOH at 800 0 C were obtained as 1333.01 m 2 /g, 0.391 cm 3 /g and 6.81, respectively. pH, reaction time, initial OTC concentration and adsorbent amounts were optimized in the adsorption study performed with LPAC with high porosity and micropores. Kinetic evaluation was made with Pseudo-First-Order, Pseudo-Second-Order and Intra-Particle Diffusion Models and Freundlich, Langmuir and Temkin equations are used to investigate their isotherms under reaction equilibrium conditions and also the results were analyzed by statistical method (ANOVA). In Pseudo Second Order kinetic and Freundlich isotherm models, where the best results were obtained, R 2 values were calculated as 0.9988 and 0.9953, respectively. Maximum OTC removal efficiency was found as 104.222 mg/g. Overall, this research indicates that LPAC for the treatment of water contaminated with antibiotics is environmentally friendly green material.

Kail sawdust charcoal was used as an adsorbent for the removal of Torque blue, red RB and yellow M4G (textile dyes) dyes from aqueous solution. Adsorption was carried out at different concentrations of dye solution, dose of adsorbent, temperature, pH and particle size. The adsorption data were best fitted by Langmuir adsorption isotherm and pseudosecond-order kinetic models. Thermodynamic parameters (∆G°, ∆H° and ∆S°) were determined, and the results indicated that adsorption was spontaneous, feasible and exothermic. Adsorption was better at higher pH for torque blue and at lower pH for red RB and Yellow M4G dyes. Kail sawdust charcoal (bio waste) would be quite effective and economical adsorbent for the treatment of textile dye wastewater.
