“…The Ni(II) adsorption increases with time and attains equilibrium at *120 min irrespective of initial concentration of Ni(II) ions. Similar equilibrium time has been reported for Ni(II) adsorption onto Turkish fly ash (Bayat 2002); however, numbers of systems are reported to have equilibrium achieved between 15 min and 1 h (Boujelben et al 2009;Hasar 2003;Suryan and Ahluwalia 2012;Green-Pederson et al 1997). On the other hand, higher equilibrium adsorption times of about 4 h are reported for chitin (Hema et al 2011)-and pine tree material (Argun et al 2010)-based adsorbents.…”

Deep ocean manganese nodules are significant futuristic resource of copper, nickel and cobalt. After recovery of these valuable metals, a huge quantity of residue (*70 % of ore body) is generated. In the present paper, investigations carried out for the application of washed manganese nodule leaching residue (wMNR) for the removal of nickel (Ni) ions from aqueous solution by adsorption are described. Several parameters have been varied to study the feasibility of using wMNR as potential adsorbent for remediation of Ni(II)-contaminated water. The adsorption kinetics followed pseudo-first-order equation, and the rate of adsorption increased with solution temperature. Kinetics data of Ni(II) adsorption were also discussed using diffusion models of Webber-Morris and Dumwald-Wagner models. The equilibrium data were best fitted into Langmuir adsorption isotherm, and the maximum adsorption capacity was found to be 15.15 mg g -1 at pH 5.5 and temperature 303 K, which decreased to 10.64 mg g -1 upon raising the solution temperature to 323 K. The activation energy for Ni(II) adsorption onto wMNR was 9.56 kJ mol -1 indicated physical sorption. Desorption studies showed successful regeneration of adsorbent and recovery of Ni. This process can be utilized for removal and recovery of Ni from the industrial effluent.

The Ni(II) adsorption capacity of carbon derived from Citrus limettioides peel (CLP), which is a novel waste material (CLPC), was evaluated regarding contact time, pH and adsorbent dose during batch adsorption processes with raw CLP. The optimal contact time for the adsorption of Ni(II) ions onto the peel and peel carbon was 3 h, and the optimal pH ranged from 5.0 to 8.0 for CLP and 4.0-8.0 for CLPC, respectively. The removal percentage decreased from 85.0 to 70.0 % for CLP and remained nearly constant (99 %) for CLPC when the initial Ni(II) concentration was increased from 10 to 50 mg L -1 . The equilibrium data fit the Langmuir isotherm with a high R 2 value, indicating that the Ni(II) ions formed a homogenous monolayer on the adsorbent surface. Adsorption capacity of Ni(II) ions on peel (CLP) and peel carbon (CLPC) was found to be 25.64 and 38.46 mg g -1 , respectively. The surface morphology and functionality of the CLP and CLPC before and after adsorption were characterized using SEM, EDX and FT-IR. Various thermodynamic parameters, including the standard Gibbs free energy (DG°), standard enthalpy (DH°) and standard entropy (DS°), were evaluated. The CLP and CLPC were tested with Ni(II) plating wastewater through a batch-mode process over five cycles; CLPC showed better results than CLP.

“…The low uptake of nickel ions in strong acidic medium may be attributed to the protonation of amine groups which leads to a strong electrostatic repulsions with the metal ion [19][20][21]. Hence, the protonated amine group obtained in lower pH medium has reduced the available binding sites for the adsorption of nickel ions.…”

Poly(ethyl hydrazide) grafted oil palm empty fruit bunch (peh-g-opefb) fiber has been successfully prepared by heating poly(methylacrylate)-g-opefb at 60 °C for 4 h in a solution of hydrazine hydrate in ethanol. The chelating ability of peh-g-opefb was evaluated based on removal of Ni(II) ions in aqueous solution. Adsorption of Ni(II) by peh-g-opefb was characterized based on effect of pH, isotherm, kinetic and thermodynamic study. This cheap sorbent based on oil palm empty fruit bunch fiber has a great future potential in water treatment industries based on high adsorption capacity, biodegradability and renewability.
