“…This is due to its excellent properties (Lambert et al 2014), such as very good electrical and thermal conductivity, ductility and availability (Samuelsson and Björkman 2014). Contamination of drinking water can occur during mining and production processes, where copper ions leak into water streams and are further distributed (Akar et al 2009;Bilal et al 2013). Apart from traditional applications, copper is also used as fungicide or fertilizer for plants and as nutrient supplement for animals, resulting in accumulation of copper in manure, ultimately causing soil contamination and thus contamination of drinking water sources (Tegoni et al 2014).…”

“…Membrane processes are usually connected to process complexity, membrane fouling and low permeate flux; coagulation-flocculation involves chemical consumption and sludge generation; and flotation causes high initial capital, maintenance and operational costs (Ujang and Anderson 1996;Qdais and Moussa 2004). Chemical precipitation is often not economically feasible and produces large amounts of sludge; ion-exchange resins are often expensive and have to be regenerated, causing serious secondary pollution; and the development of electrochemical heavy metal wastewater treatment techniques is restricted due to high initial capital investment and expensive electricity supply (Kongsricharoern and Polprasert 1995;Akar et al 2009). The use of activated carbons for the adsorption of heavy metal ions is restricted due to its high cost (Fu and Wang 2011), while utilization of low-cost adsorbents is often limited by their adsorption efficiencies (Cretescu et al 2015;Komkiene and Baltrenaite 2016).…”

Copper is a major problem in industrial wastewater streams, seriously affecting the quality of potential drinking water. Several approaches, including continuous membrane processes or batch-wise application of adsorbents, are in use to tackle this problem. Unfortunately, these processes suffer from their particular drawbacks, such as low permeance or disposal of saturated adsorbents. However, a combination of these processes could constitute a step towards a more efficient copper removal solution. Here, we present a nanopaper ion-exchanger prepared from cellulose nanofibrils produced from fibre sludge, a paper industry waste stream, for the efficient, continuous removal of copper from aqueous solutions. This nanopaper ion-exchanger comprises phosphorylated cellulose nanofibrils that were processed into nanopapers by papermaking. The performance of these phosphorylated nanopaper membranes was determined with respect to their rejection of copper and permeance. It was shown that this new type of nanopaper is capable of rejecting copper ions during a filtration process by adsorption. Results suggest that functional groups on the surface of the nanopapers contribute to the adsorption of copper ions to a greater extent than phosphate groups within the bulk of the nanopaper. Moreover, we demonstrated that those nanopaper ion-exchangers could be regenerated and reused and that in the presence of calcium ions, the adsorption capacity for copper was only slightly reduced.

“…The use of Langmuir isotherm in fitting the data to remove metal ions from synthetic solutions has been reported with good results [12][13][14][15][16] . The essential characteristics of Langmuir isotherm can be expressed by the constant dimensionless number, separation factor or equilibrium parameter (R L ), which indicates the curvature of the sorption isotherm: if R L > 1, the isotherm is not favorable; if R L = 1, it is linear; 0 < R L < 1, favorable; R L = 0, irreversible.…”

A kinetic and equilibrium study of zinc removal by Brazilian bentonite clay

This paper aimed to study the removal of zinc using bentonite clay from the Northeastern Brazil, as an adsorbent. A study of the clay subjected to thermal and chemical treatment was performed in order to evaluate the optimization of the adsorption capacity of this material. For the evaluation of the kinetic equilibrium of the process, experimental tests were carried out in a finite bath system. The maximum amount of metal adsorbed was 0.151 mEq of metal per gram of calcined clay and 0.257 mEq of metal per gram of sodium saturated clay. The kinetic models of pseudo-first order, pseudo-second order and intraparticle diffusion were fitted to experimental data, and the pseudo-second order model provided the best result. The Langmuir and Freundlich models were used for the adsorption equilibrium analysis, and the Langmuir model provided the best fit for sorption isotherms. The physicochemical characterization of clay involved X-ray diffraction, scanning electron microscopy, chemical analysis by energy-dispersive X-ray spectroscopy, helium pyconometry and thermogravimetric analysis. The modified clay has potential use for removing Zn 2+ ions replacing more expensive adsorbents, since good adsorption properties will be also associated with great availability and low cost.

“…The cell walls of these fungi have high metalbinding capacities and may also show high values of intracellular accumulation (de Rome and Gadd 1987). Heavy metals are toxic and carcinogenic to a variety of aquatic organisms, even at very low concentrations (Akar et al 2009). Among these metals, nickel is the predominant soluble ion in waste streams (Wang et al 2007).…”

The Pb(II) and Ni(II) biosorption of a fungal biomass isolated from mine drainage of metal-processing industries in Balya (Balıkesir province, Turkey) was optimized using a response surface methodology by altering parameters such as pH, initial metal concentration, contact time and biosorbent dosage. This strain was shown to be highly similar to Penicillium sp. Furthermore, zeta potential measurements and Fourier transform infrared spectroscopy were performed to understand the adsorption mechanism. A Box-Behnken design with 29 experiments was used to evaluate the interactions between independent variables. The results showed that the fungal biomass isolated from the metal mine drainage could have a significant environmental impact through the biosorption of Pb(II) and Ni(II) in waters polluted with heavy metals, particularly in the drainage from metal mines. The maximum removal values were 76 and 47 % at pH 4.5 for both Pb(II) and Ni(II), with 123 and 33 mg/L initial metal concentrations, 65 and 89 min contact times and 0.2 and 1.6 g/L biosorbent, respectively.
