Thermo-gravimetric analysis reveals that all activated carbon samples were thermal stable up to ~ 850 °C. FTIR spectrum shows appearances of minor functional groups in the activated carbons.doi:10.1007/s40034-020-00176-zGeeta KumariBhavin Soni...
The FTIR analysis showed that the reaction was successful, and methylene blue was present on the adsorbent surface. The methylene blue adsorption test indicated that 388 mg/g of the dye was adsorbed (97% dye removal), and the final concentration reached 6 mg/L after 8 h. The point of ...
In this work, the methanol oxidation reaction is investigated on Ni based metal organic frameworks (MOF) and its composites with biomass derived activated carbon. NiO-MOF and composites with activated carbon were synthesized using hydrothermal method. SEM, EDX, and XRD, FTIR, TGA techniques were ...
The hydrochar formed by this technique was proven to have high surface area50 which in turn could well serve as a pre-treated material for activated carbon production. For the resultant ACs, the obtained spectra were similar to the hydrochar spectrum. However, the peak intensity of C–H ...
The shifting of peaks in FTIR spectrum confirmed the GRL and DY 12 dye adsorption onto CSAC. The SEM study also made support to it by observing difference in surface morphology of adsorbent before and after adsorption of GRL and DY 12. Kinetics adsorption models of both GRL and DY 12 dyes...
Fig. 5. FTIR spectrum of CN. ABR effluent characteristics As shown in Table 4, its been observed that the effluent failed to meet the Ghana Environmental Protection Agency (GH EPA) standards for discharge of wastewater with respect to a number of the parameters measured especially nitrogen, phos...
FTIR spectrum of PEI-impregnated and nonimpregnated ACNFs and GRHC/ACNFs. The SEM, TEM images, and EDX mapping of PEI-impregnated GRHC/ACNFs is presented in Figure 8(a)–(d). As shown in Figure 8(a), it can be seen that the morphology of PEI-GRHC/ACNF was agglomerated with appeara...
Before the experiments the surface of the adsorbents was characterized by using the sorption of nitrogen, Boehm and potentiometric titrations, thermal analysis, and FTIR. The adsorbents were chosen to differ in their surface areas, pore volumes, and surface acidities. To broaden the spectrum of ...
FTIR spectrum:araw rice husk;bRHAC Full size image Effect of process parameters on breakthrough curves Effect of flow rate The experiments for the effects of flow rate on breakthrough curves were carried out at an influent phenol concentration, 100 mg/L, bed height, 10 cm, particle size, ...
The amount of material lost during the physical activation step followed the order Control > Zinc chloride > Phosphoric acid-activated carbon. However, the % Hardness surprisingly also followed the same order. We would have expected that increase in material hardness would translate into ...
