Simple One-Step Synthesis of Nipa Frond-Derived Magnetic Porous Carbon for Decolorization of Acid Yellow 23

Nipa is an abundant, underutilized palm whose major part its fronds. fronds (NF) were, therefore, valorized as a renewable carbon resource for the preparation of advanced magnetic porous (MPC) via simple one-step pyrolysis with FeCl3 addition precursor. Properties obtained material were determined by X-ray diffraction (XRD), nitrogen adsorption and desorption isotherms, vibrating sample magnetometer (VSM), scanning electron microscopy (SEM) images, energy-dispersive (EDX) spectroscopy, Fourier-transform infrared (FTIR) spectroscopy. XRD results showed that Fe3O4 along Fe0 particles formed in base. FeCl3-activation NF yielded MPC high specific surface area (SBET) 330 m2/g, large total pore volume (Vtotal) 0.26 cm3/g, strong saturation magnetization 7.65 emu/g. Subsequently, was explored removal acid yellow 23 (AY23) using H2O2 oxidation agent. Before addition, (0.80 g/L) at pH 3.0 partly eliminated AY23 (initial 100 ppm) capacity 14.5 mg/g. In further catalytic 200 ppm H2O2, removed 89.1% within 120 min. Moreover, decolorization different samples obeyed pseudo-first-order kinetics, greatest rate constant being 0.0186 min?1. Interestingly, utilized could be easily from treated media magnet. Altogether, findings suggest low-cost produced FeCl3-loaded nipa frond might applied to treatment wastewater due relative capacity, efficient performance, powerful separability.
