Biosorptive removal of Cu(II), Ni(II) and Pb(II) ions from aqueous solutions using coconut dregs residue: Adsorption and characterisation studies

Application of Kenaf Bast Fiber to Adsorb Cu(II), Pb(II) and Zn(II) in Aqueous Solution: Single- and Multi-metal Systems

“…This scenario can be explained by the fact that there was a high probability of collision between adsorbent surface and metal ions at high concentrations. Therefore, the rate of diffusion of metal ions towards the adsorbent surface was expected to increase [2].…”

“…Rapid industrialization and global urbanization have released significant amount of heavy metals into the environment [1], [2]. Industrial activities such as electroplating, alloys and acid batteries manufacturing and, electrical components and paints manufacturing are the main sources of heavy metals [3], [4].…”

“…In recent decades, adsorption is the most employed and has been regarded as an effective technique to remove heavy metals in wastewater [2]. Activated carbon has been widely used as an adsorbent for water treatment [13].…”

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

“…Industrial applications of adsorption processes require information from a systems design perspective, in which, adsorption studies alone have proven to supply insufficient information of adsorption reaction pathways (Kamari et al, 2014). Thus, kinetic models were used to investigate the kinetic equilibrium sorption of Eu(III) and was investigated by time-course equilibrium studies of the metal sorption onto chitosan powder, chitosan beads and Arthrobacter sp.…”

Adsorption Kinetics, Equilibrium, and Thermodynamics of Copper From Aqueous Solutions using Silicon Carbide Derived from Rice Waste

“…8-10). The values of Langmuir constants q m and b were (22.06 mgg -1 ) and (0.03) respectively.Value of q m was found to be higher than the adsorption capacity of other adsorbent reported in the literature: rice husk carbon (21.01mgg -1 )[11], count dregs residue (2.76 mgg -1 )[26], rice husk (1.617 mgg -1 ) and H 3 PO 4 treated rice husk (17.03 mgg -1 )[27]. The value of R L is 0.26 assign a highly favorable sorption of Cu ion solutions.…”
