Water pollution caused by dye is a serious challenge. Herein, we use novel discharge process to functionalize carbon nanotube (CNT) COOH groups form CNT30 for removing methyl red (MR) from water. By pristine CNT, 75% MR removed in 60 min, with an adsorption capacity of 68.44 mg g-1. CNT30, 85% fast only 5 and the removal efficiency reaches 95% after 30 80.33 Thus, higher achieved much shorter time on CNT30. Moreover, has outstanding reusability, decreasing 7% ten cycles. The improve hydrophilicity thus promoting interaction water hydrogen bonding electrostatic could be force drive content origin better performance developed herein operated O2, without using harmful substances, CNT can efficiently tuned simply changing time. This different chemical modification widely used strong oxidants, e.g., HNO3. present work great significance realize green construction materials more

Mesoporous biochar derived from Egyptian doum palm (Hyphaene thebaica) shells as low-cost and biodegradable adsorbent for the removal of methyl orange dye: Characterization, kinetic and adsorption mechanism

Chemical Physics Impact, Год журнала: 2023, Номер 8, С. 100446 - 100446

The present research work reports the preparation of Hyphaene thebaica derived-biochar (HTBC) and its applicability as eco-friendly low-cost adsorbent for removal methyl orange (MO) dye. main physicochemical characteristics HTBC including morphology, crystallinity chemical function groups were determined through scanning electron microscopy (SEM), energy dispersion spectroscopy (EDS), powder X-ray diffraction (XRD) Fourier transform infrared (FTIR). results showed that was found to be constituted by heterogeneous surface with mesoporous having a area 33.38 m2/g pore diameter 23.53 nm, carboxylic amine functional groups. Adsorption experiments conducted using batch mode, varying key adsorption parameters such contact time, solution pH, dosage concentration. isotherm modelling revealed Langmuir model (higher R2 lower χ2) provided better fit MO onto HTBC, while kinetics followed pseudo-second-order kinetic model. Under optimized conditions (pH 2, dose 0.03 g, initial dye concentration 100 mg/L, 313 K, 270 rpm), maximum monolayer capacity 264.922 mg/g. According thermodynamic parameters, it can deduced on exothermic spontaneous. mechanism attributed various interactions, electrostatic attraction, H-bonding, π-π interaction. In light these findings, biochar from shells considered cost-effective biodegradable significant potential treatment water contaminated anionic dyes.
