Utilization of NaOH modified Desmostachya bipinnata (Kush grass) leaves and Bambusa arundinacea (bamboo) leaves for Cd(II) removal from aqueous solution

Sorption of cadmium (II) ion from aqueous solution onto sweet potato (Ipomoea batatas L.) peel adsorbent: Characterisation, kinetic and isotherm studies

“…The ash content and moisture content of these residues reported by Oladayo (2010) were; 3.95, 12.67, 7.76 and 6.06 (% ash content) and 5.34, 10.04, 11.99 and 8.71(% moisture) for coconut husk, cocoa pods, kola nut pods and plantain peels respectively. Also the moisture content, ash content and pHpzc of the PTPS adsorbent are similar to those reported by Pandey et al, (2015) for Kush grass and bamboo leaves adsorbents. The PTPS adsorbent has a high volatile matter content which is characteristics of the organic nature of the lignocellulosic biomass which contains cellulose, lignin and hemicellulose (Khor et al, 2009).…”

“…hydroxyl groups associated with cellulose, lignin, hemicellulose, extractives and pectin (Pandey et al, 2015). The shift in the vibrations of the functional groups after metal ion sorption as observed in FTIR spectrum of the PTPS adsorbent after Cd(II) adsorption can be explained based on the change in coordination sites of the functional groups due to the interactions with the Cd(II) ion.…”

Pb(II) Removal from Aqueous Solution by <i>Cucumissativus</i><i> </i>(Cucumber) Peel: Kinetic, Equilibrium &amp; Thermodynamic Study

“…The q m values compared to maximum adsorption capacity obtained by some other researcher are quite higher [18][19][20][21][22][23]. The adsorption capacity is quite high with the finding of our previous studies for removal of Cd(II) ion using Cucumissativus (q max , 3.597 mg/g) [7] and NaOH modified Desmostachyabipinnata Leaves(q max , 19.84 mg/g) & Bambusaarundinacea Leaves (q max , 19.71 mg/g) [24] at room temperature i.e. 298K.A little difference in adsorption capacity was observed i.e.…”

Removal of various contaminants from water by renewable lignocellulose-derived biosorbents: a comprehensive and critical review

“…Furthermore, Pandey et al (2015) reported that the porosity of Kush grass and bamboo leaves only accounts for 0.11% and 0.15%, respectively. Therefore, the role of the pore filling mechanism in the biosorption process of contaminants in aqueous media is negligible.…”
