Synthesis and characterization of microporous granular activated carbon from Silver berry seeds using ZnCl2 activation: Fullerenes, Nanotubes and Carbon Nanostructures: Vol 0, No 0

Summary

Granular activated carbon (GAC) was synthesized from Silver berry (Elaeagnus Angustifolia L.) seeds utilizing zinc chloride because the activation agent. To optimize the working parameters, the consequences of the time and temperature of carbonization, impregnation ratio, and heating fee on the iodine quantity and yield of activated carbon had been studied. Optimized parameters had been impregnation ratio of 1:1, carbonization temperature of 500 °C, carbonization time of 1 hour, and heating fee of 5 °C/min. The GAC synthesized beneath optimized situations was characterised by Nitrogen adsorption-desorption isotherms, SEM, EDX, XRD, FT-IR, Boehm titration, TG-TGA, and TG-IR. It was discovered that the synthesized GAC has a microporous construction with a BET floor space of 1109 m2/g, a micropores quantity of zero.317 cmthree/g, and a median pore diameter of two.1 nm. The methylene blue (MB) dye was employed as a molecule mannequin to guage the porosity and the adsorption capability of the synthesized GAC. The outcomes confirmed that the utmost adsorption capability of MB and the % portion of the floor space (SMB/SBET) had been 120.48 mg/g and 30.62%, respectively. The experimental outcomes reveal that the synthesized GAC can be utilized as a low-cost adsorbent for the elimination of small and huge environmental pollution.
