“…Also, PBP showed signals at 1395–1400 cm −1 , which could be assigned to lignin symmetric CH deformation, lignin OCH 3 deformation, CH 3 bend, aromatic ring breathing mode, substituent CC bonds and cellulosic CH 2 bend. The vibration modes of 3100 cm −1 and 3270 cm −1 represent CN and CH aromatic ring bends .…”

The adsorption capacities of Parkia biglobosa chaff biomass (PBC) and Parkia biglobosa pulp biomass (PBP) for Cr(III), Cd(II), Ni(II), and Pb(II) ions were studied. Experimental data suggested the highest monolayer sorption capacities of PBC and PBP, q maxL at equilibrium to be 170.07 mg/g at pH 7.0 and 324.68 mg/g at pH 6.0, for the uptake of Cr(III) ions, respectively. The minimum adsorption capacities obtained by PBC and PBP were 60.72 mg/g for Ni(II) and 16.70 mg/g for Cd(II) at pH value of 2.0, respectively. Pseudosecond order kinetic model fits the all experimental data best, suggesting that the entire adsorption processes might have occurred by chemisorption mechanism. Thermodynamic data indicated that the adsorption of various metal ions by PBC and PBP was endothermic, with increase in disorderliness of the system. The Gibb's free energy values for the uptake of Cr(III), Cd(II) and Ni(II) ions by PBC indicated the spontaneity of the processes. Moreover, the Gibb's free energy values for the uptake of Pb(II) ion by PBC depicted the non spontaneity of the processes. Also, Gibb's free energy values for the adsorption of various metal ions by PBP depicted the spontaneity of the processes.

Abstract: amount of non-methoxylated phenol, which is consistent with sugarcane's classification as a non-woody angiosperm. The location of the phenyl ring breathing mode peaks do not shift in ethanol, methanol, isopropanol, 1,4 dioxane or acetone.
