“…There are various methods available for the removal of metals and dyes, such as adsorption [10,11], photo-degradation [12][13][14], ion exchange [15], oxidation [16], etc. Among these available methods, adsorption is proven to be an economical and efficient method which may be feasible for industrial scale operation [17]. The adsorbents required to adsorb metal and dyes from these industry effluents are required to have properties such as higher surface area, high thermal stability and small pore diameters.…”

In the present study, an alumina nanoparticle adsorbent is developed using solution combustion synthesis method and is further utilized for the removal of zinc (Zn(II)) and color black G (CBG) from wastewater. The developed adsorbent is characterized using SEM-EDS technique. The effect of various parameters such as the initial concentration, the contact time, the mass of adsorbent and the solution pH are studied for the removal of Zn(II) and CBG. The equilibrium time for both, Zn(II) and CBG is obtained to be approximately 4.5 h. The maximum adsorption of Zn(II) is found at pH value of 7 while the maximum removal of CBG is obtained at pH value of 2. The Langmuir isotherm model is found suitable for explaining the adsorption behavior of Zn(II) (R 2 = 0.976) and CBG (R 2 = 0.974) onto alumina nanoparticles, which supports the monolayer formation of Zn(II) and CBG during the adsorption process. The maximum adsorbent capacity of alumina nanoparticles for the removal of Zn(II) and CBG are obtained as 1,047.83 and 263.16 mg g -1 , respectively. The kinetic data obtained during the experiments are better fitted with the pseudo-first-order model for both, Zn(II) (R 2 = 0.989) and CBG (R 2 = 0.971). A statistical analysis is also carried out to develop the mathematical equation which relates the different independent parameters (initial metal concentration, pH, time and mass of adsorbent) with the dependent parameter (adsorption capacity). The optimum values of independent parameters are estimated using Microsoft Solver.

“…It is well-known that SPE is one of the most efficient techniques used for the separation and pre-concentration of heavy metals from water solutions (Zaporozhets et al 1996), because it is simple, does not consume large volumes of toxic organic solvents and is capable of achieving high enrichment factors (Cheng et al 2012;Huang and Hu 2008). Thus, MNs are used to retrieve toxicants such as Cr(III) (Cheng et al 2012;Song et al 2011), Pb(II) (Cheng et al 2012;Huang and Hu 2008;Li et al 2011;Madrakian et al 2012;Xu et al 2012), Cu(II) (Cheng et al 2012;Huang and Hu 2008;Podzus et al 2012), Hg(II) (Huang and Hu 2008;Li et al 2011;Song et al 2011), Cd(II) (Gong et al 2012;Huang and Hu 2008;Song et al 2011), as well as Zn(II) (Cheng et al 2012) and Mn(II) (Song et al 2011) from a variety of solutions.…”
