“…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).…”

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.

“…These methods include chemical oxidation, reduction, chemical precipitation, solvent extraction, ion-exchange, adsorption, membrane filtration, coagulationflocculation, flotation and electrochemical methods (Suzuki 1997;Ochie et al 2008;Barakat, 2011;Fenglian and Wang, 2011). Among these methods, the adsorption can be an effective method in heavy metals treatment (Huang and Morehart, 1990;Bayat, 2002;Suzuki et al, 2005;Ahmad et al 2010;Bilal et al 2013). Huge economic sorbents can be used as materials which are abundant in nature or can be originated as a waste or byproduct from industry.…”

This study investigated the copper (Cu +2 ) removal from aqueous solution by cement kiln dust (CKD) as industrial by-product in cement manufacturing process. CKD was identified by Fourier transform infrared (FTIR), scanning electron microscopy (SEM) and surface areas show the differences of physicochemical properties. Batch equilibrium experiments were carried out at 20, 25 and 30 o C with time intervals extended to 96 h to investigate the efficiency of the CKD in the removal of Cu +2 . CKD expressed high affinity for removal of Cu +2 and was not affected by temperature or time. The removal of Cu +2 was indicated by changes of FTIR and SEM images before and after sorption experiments. The kinetic data were evaluated by fractional power, Elovich, pseudo-first order and pseudo-second-order kinetic models. The kinetic studies demonstrated that rate of the removal followed pseudo-second-order kinetic model (r 2 =0.99). Thermodynamic parameters, the change of free energy (ΔG•), enthalpy (ΔH•) and entropy (ΔS • ) were calculated for predicting the nature of adsorption. The parameters showed that the process was feasible, spontaneous and exothermic under experiment conditions. Solubility equilibrium for various expected copper compounds was estimated and the solubility of copper in Cu-CKD system suggested to be controlled by Cu CO 3 precipitation under experiment condition. The results indicated that CKD can be used as a low cost and effective sorbent for copper ions from aqueous solutions.

“…Some of the dyes are toxic, carcinogenic, reported to have connections with different respiratory disorders worldwide and induces pollution to the environment [3,4]. Various techniques have been developed in investigation of processes of pollutant removal [5]. The research proved to treatment using natural materials such as clays for removing dye pollutants from wastewater has been gaining more attention because of the low-cost of the materials involved and their high specific area, and a variety of surface and structural properties [6,7].…”

Bentonite clay from Maghnia (North West Algeria) has been acid-activated. The activated bentonite was employed as adsorbent for the removal of methyl green from aqueous solutions using adsorption method. The influence of several parameters (kinetics, contact time, sorbent amount, adsorbate concentration and pH) on the adsorption capacity was evaluated and discussed. The Langmuir adsorption model was applied to experimental equilibrium data and the isotherm constant was calculated. The results indicated that the adsorption was favourable at neutral pH. This model provided the best fit to the experimental data with high correlation coefficient (R 2 = 0.996). The monolayer adsorption capacity of activated bentonite found to be 353.33 mg/g. It was seen that pseudo-first order equation describes the adsorption kinetics. The results indicated that this bentonite-type clay is potential to be used as an economical adsorbent for the removal of methyl green dye.
