Water resources suffer from many pollutants that highly affect their quality, one of these pollutants are synthetic dyes from industrial wastewater. Recently, there has been an increase in the use of biochar, a solid material derived from the thermal decomposition of different biomass, in water treatment. Therefore, this study synthesized pristine and NaOH pre-treated biochar derived from date palm trunks waste to remove cationic dye from the aqua medium. Different techniques were used to evaluate the effect of NaOH modification on biochar properties. The treated date palm trunks biochar (T-DPTBC) has a surface area of 101.67 m2. g-1, which is greater than the surface area of the untreated biochar (4.1 m2. g-1). The T-DPTBC displayed a honeycomb-like microporous structure with an average pore diameter of 6.51 nm. The adsorption performance of an cationic dye Crystal Violet (CV) was investigated through batch experiments. The maximum adsorption capacity of T-DPTBC for CV dye at pH 6 was 96.2 mg. g-1 with 98% dye removal efficiency. The Langmuir model better described the adsorption isotherm (R2=0.964), indicating a monolayer adsorption process on the surface of biochar. According to the findings of this work, T-DPTBC is a sustainable adsorbent material for dye removal from aqueous media. [ABSTRACT FROM AUTHOR] |
