“…The adsorption capacity is influenced strongly by the surface structures of carbon–oxygen–hydrogen functional groups and the surface behaviour of carbon 3, 38. Wood, coconut shell and husk are made up of three dominant components, namely, cellulose, lignocellulose and lignin with varieties of functional groups as seen in Fig 5.…”

BACKGROUND: In Ghana, the discharge of untreated gold mine wastewater contaminates the aquatic systems with heavy metals such as copper (Cu), threatening ecosystem and human health. The undesirable effects of these pollutants can be avoided by treatment of the mining wastewater prior to discharge. In this work, the sorption properties of agricultural materials, namely coconut shell, coconut husk, sawdust and Moringa oleifera seeds for Cu(II) were investigated.

“…However, most of these methods have some disadvantages such as complicated treatment process, high cost, and high energy demand. Among these methods, adsorption (ads) is considered as the most widely used method due to high performance, economical feasibility, and simple application [17,27,36,52,89,92]. In general, activated carbon is the most commonly used adsorbent for the removal of heavy metals from industrial wastewater due to its high surface area, microporous structure, and high adsorption capacity.…”

The present study investigates the removal of copper ions (Cu (II)) from aqueous solution using chemically treated rice husk (TRH). The chemical treatment was carried out using NaOH solution and the effect of contact time (tc), adsorbent dosage (Dad), initial Cu (II) concentration ([Cu]i), and temperature (T) on the percentage removals of Cu (II) (%RCu) were investigated. Different analytical techniques (FTIR, SEM, and EDX) were used to confirm the adsorption (ads) of Cu (II) onto the TRH. The ads kinetics was tested against pseudo-first-order (PFO) and pseudo-second-order (PSO) models as well as Langmuir and Freundlich isotherms. Treating RH with NaOH altered the surface and functional groups, and on the surface of RH, the ionic ligands with high electro-attraction to Cu increased and thus improved the removal efficiency. The %RCu decreased by increasing the [Cu]i and increased by increasing the ct, Dad, and T. Up to 97% Cu removal was achieved in ct of 30 min using Dad of 0.3 g [Cu]i of 25 mg L−1 and T = 280 K. The ads of Cu on TRH is endothermic, spontaneous, follows Langmuir isotherms, and exhibited a PSO kinetics. Moreover, the TRH was successfully regenerated and used for further adsorption cycles using 1 M HNO3.

“…Environmental contamination of heavy metals has become a worldwide problem and a special attention has been given to them because of their high toxicity, nonbiodegradability, and accumulation in the food chain (Javanbakht et al., 2011; Kumar et al., 2014; Kumari et al., 2015; Kumari and Tripathi, 2015; Mendoza-Castillo et al., 2015; Moftakhar et al.; Singh and Prasad, 2015; Song et al., 2011; Xu et al., 2012a). The heavy metal sources from industry include fertilizers, pigments, batteries, and so on (Javanbakht et al., 2014; Mahdavi et al., 2012; Nędzarek et al., 2015; Sarioglu et al., 2009; Şen et al., 2015; Tan et al., 2012). Heavy metals, even at trace level, are very harmful for human beings.…”

The present study focuses on the response surface methodology (RSM) for the optimization of lead removal from an aqueous solution by a novel superparamagnetic nanocomposite. A rotatable central composite design and the response surface methodology were used to conduct and to analyze the experiments, respectively. The adsorption process was investigated as a function of the four factors consisting of pH (4.0-6.0), temperature (20 C-60 C), initial lead concentration (10-90 mg/L) and adsorbent dosage (0.2-1.0 g/L). The maximum lead adsorption capacity was obtained to be 124.955 mg/g under the optimal conditions of 5.49, 60 C, 89.08 mg/L, and 0.48 g/L for the solution pH, temperature, initial lead ion concentration, and the adsorbent dosage, respectively. The desirability function was used to find an optimum point where the desired conditions could be obtained. The superparamagnetic nanocomposite could be used as an adsorbent for the removal of toxic heavy metals from water and wastewater.
