Kinetics, Isotherms and Equilibrium Study of Co(II) Adsorption from Single and Binary Aqueous Solutions by Acacia nilotica Leaf Carbon

Facile synthesis of chitosan derivatives and Arthrobacter sp. biomass for the removal of europium(III) ions from aqueous solution through biosorption

“…In addition, for the chitosan beads, due to the higher observed correlation coefficient of the Temkin adsorption isotherm, this postulates that for these molecules in that monolayer, the heat of adsorption decreased with surface coverage due to the increase in Eu(III)/biosorbent interactions (Hosseini et al, 2003;Thilagavathy and Santhi, 2014). The values for SEE and SSE for the equilibrium isotherms are presented in Table 1 and the values were compared for each model.…”

Efficacy of unmodified and chemically modified Swietenia mahagoni shells for the removal of hexavalent chromium from simulated wastewater

“…In addition these methods are incompatible, especially when the metal concentration is lower than 100 mg/L [9,10]. Among the conventional treatment methods, adsorption seems to be the technique with the most potential for the sequestration of various heavy metal ions from industrial wastewaters [11]. The expenditure associated with commercial activated carbon production makes the adsorption process costly.…”

Adsorption of hexavalent chromium from synthetic and electroplating effluent on chemically modified Swietenia mahagoni shell in a packed bed column

“…Activated carbon can be prepared from the organic material rich in carbon and low inorganic content (Bhatnagar and Sillanpaa 2010;Binglu et al 2014;Li et al 2008). Many attempts have been made to obtain activated carbons from the plant biomass wastes including Sterculia guttata shell (Rangabhashiyam and Selvaraju 2015a), Jatropha hull (Duan et al 2011), Maize cob (Okoya et al 2015), sour cherry stones (Angin 2014), acorn shell (Saka 2012), Aegle marmelos correa (Anandkumar and Mandal 2009), Acacia nilotica Leaf (Thilagavathy and Santhi 2014), coconut shell [Okoya et al 2016], longan seed (Jinbei et al 2015), Eichhornia crassipes root (Anil et al 2012), cocoa husk [Okoya et al 2014], peanut shells (Wu et al 2013), etc. Activated carbon can be produced through two different processes such as physical activation and chemical activation.…”
