“…Among these methods, the adsorption process is extensively considered as an effective and efficient approach due to its low cost, easy handing, the availability of various adsorbents, and its environment-friendly properties [ 1 ]. To date, there has been plenty of literature regarding Zn removal on various adsorbents such as active carbon [ 7 ], carbon nano-materials [ 8 ], magnetic nanoparticle [ 9 ], nano-scale zero-valent iron [ 10 ], mineral [ 4 , 11 ], etc. Ggasemi et al (2015) demonstrated that the maximum adsorption capacity of Zn(II) was only 24.21 mg/g using dioctylphetalate triethylenetetraamine magnetic nanoparticles [ 9 ].…”

Therefore, the development of highly efficient adsorbents for Zn(II) removal was still required, especially for actual application in environmental clean-up operations.…”

Graphene oxide (GO) was synthesized and employed as an adsorbent for Zn(II) removal from an aqueous solution. The adsorption isotherms showed that Zn(II) adsorption can be better described using the Freundlich model than the Langmuir model. The maximum adsorption capacity of Zn(II) on GO determined using the Langmuir model at pH 7.0 and 293 K was 208.33 mg/g. The calculation of thermodynamic parameters revealed that the process of Zn(II) adsorption on GO was chemisorptions, endothermic, and spontaneous. Kinetic studies indicated that the pseudo-second-order kinetic model showed a better simulation of Zn(II) adsorption than the pseudo-first-order kinetic model. On the basis of surface complexation modeling, the double layer model provided a satisfactory prediction of Zn(II) by inner-sphere surface complexes (for example, SOZn+ and SOZnOH species), indicating that the interaction mechanism between Zn(II) and GO was mainly inner-sphere complexation. In terms of reusability, GO could maintain 92.23% of its initial capability after six cycles. These findings indicated that GO was a promising candidate for the immobilization and preconcentration of Zn(II) from aqueous solutions.

In this study, Magnetite-hydroxyapatite nanocomposites were prepared by in situ precipitation of the calcium phosphate phase in an iron oxide colloidal suspension. Adsorption of cobalt was initially rapid and the adsorption process reached a steady state after 180 min. The Co(II) adsorption capability of the MHAp was investigated as a function of temperature, pH, ionic strength, adsorbent dosage, agitation speed and initial Co(II) concentration. Theincrease in pH and temperature resulted in an increase in Co(II) adsorption capacity; Increasing ionic strength increased the adsorption of Co(II) by MHAp; The adsorption isotherms were well described by the Freundlich model, Langmuir, Temkin and D-R models. The Freundlich model was found to provide the better fit with the experimental data. Different types of adsorption kinetic models were used to describe the Co (II) adsorption behaviour, and the experimental results fitted the pseudo-second-order kinetic models well. Thermodynamics parameters such as ∆H o , ∆S o , ∆G o revealed that the adsorption of Co(II) by MHAp was endothermic in nature, physisorption, spontaneous at 308 and 318K.

“…These materials have progressively gained attention due to their unique physicochemical properties such as dimension, shape, composition, and crystallinity . NPs are particles having specific features such as high adsorption capacities and large surface areas they also have high mobility in porous media, which could be attributed to their specific functionality and surface area (per unit mass), their smaller size in comparison to the relevant pore spaces, and their simple surface functionality for modifying . Adsorbent materials could be productive in carbon materials and are mainly combined with NPs to obtain a composite shape.…”

In the present work, Mn‐doped CuO‐NPs‐AC was prepared by a simple method, characterized using various techniques such as FESEM, EDX, XRD, PSD, and pHpzc and finally used for the adsorption of malachite green (MG) and methyl orange (MO) in a number of single and binary solutions. A series of adsorption experiments were conducted to investigate and optimize the influence of various factors (such as different pH, concentration of MG and MO, adsorbent mass, and sonication time) on the simultaneous adsorption of MG and MO using response surface methodology. Under optimal conditions of pH 10, adsorbent dose of 0.02 g, MG concentration of 30 mg L−1, MO concentration of 30 mg L−1, and sonication time of 4.5 min at room temperature, the maximum predicted adsorption was observed to be 100.0%, for both MG and MO, showing that there is a favorable harmony between the experimental data and model predictions. The adsorption isotherm of MO and MG by Mn‐doped CuO‐NPs‐AC could be well clarified by the Langmuir model with maximum adsorption capacity of 320.69 mg g−1 and 290.11 mg g−1 in the single solution and 233.02 mg g−1 and 205.53 mg g−1 in the binary solution by 0.005 g of adsorbent mass for MG and MO, respectively. Kinetic studies also revealed that both MG and MO adsorption were better defined by the pseudo‐second order model for both solutions. In addition, the thermodynamic constant studies disclosed that the adsorption of MG and MO was likely to be influenced by a physisorption mechanism. Eventually, the reusability of the Mn‐doped CuO‐NPs‐AC after six times showed a reduction in the adsorption percentage of MG and MO.
