“…Several appropriate technologies are available including precipitation (Safdar et al, 2011), solvent extraction (Hung et al, 2007;Shamsipur et al, 2009), membrane filtration (Borbély and Nagy, 2009;Trivunac and Stevanovic, 2006;Xiang Li et al, 2013), cementation (Aktas, 2011(Aktas, , 2012Morcali et al, 2013c), ion exchange (Godlewska-Żylkiewicz et al, 2000;Shen et al, 2010Shen et al, , 2011 and adsorption (Fırlak et al, 2013;Kyzas et al, 2013;Wang et al, 2011). Comparatively, adsorption seems to be the most suitable as large volumes of very dilute wastes can be treated economically and nearly no waste residue is produced (Morcali et al, 2013a).…”

“…Comparatively, adsorption seems to be the most suitable as large volumes of very dilute wastes can be treated economically and nearly no waste residue is produced (Morcali et al, 2013a). A number of adsorbents have been developed and tested for the recovery of precious metals such as activated carbon (Aktas and Morcali, 2011b;Navarro et al, 2006), membranes (Xiang Li et al, 2013), and chelating resins (Atia et al, 2005;Birinci et al, 2009;Shen et al, 2011). In recent years, chelating sorbents have received increasing attention as adsorbents for the removal of metal ions from contaminated water/wastewater.…”

“…Through a comparison of Pt sorption capacities of the sorbents (Table 3), it is shown that the newly developed PWPAN has a higher Pt uptake than the activated carbon [20], commercial anion exchange resin (Diaion WA21J) [21], graphene oxide [22], and some artificially modified sorbents e.g., thiourea-modified chitosan [23], biopolymer modified activated carbon [20], polysulfone-based fibers [5], glycine-modified crosslinked chitosan resin [24], and PEI-modified E. coli [25]. Meanwhile, the sorption capacity of the PWPAN was lower than those of the M500, the ethylenediamine-modified magnetic chitosan nanoparticles [26], and some polymer-immobilized sorbents, e.g., polymer-immobilized polysulfone-based fibers [5], poly(allylamine hydrochloride)-modified E. coli [27], and poly(allylamine hydrochloride)-modified E. coli /chitosan fiber [28].…”

The Preparation of Modified Industrial Waste Polyacrylonitrile for the Adsorptive Recovery of Pt(IV) from Acidic Solutions

et al. 2016

Sorption technique is one of the most effective methods for recovering precious metals from wastewater solutions; however, its main drawbacks of the traditional sorbents are the slow kinetics and relatively low sorption capacities. As a solution, thin sorbent fibers have been highlighted because they can lead to fast adsorption kinetics due to their high surface areas and numerous binding sites. In this sense, the applicability of an industrial waste polyacrylonitrile (PAN) textile was examined to recover Pt(IV) from acid solutions. In order to enrich cationic functional groups on the surface of a PAN textile, the textile was chemically modified via polyethylenmine (PEI) coating. Afterwards, using PEI-coated PAN fiber, batch sorption experiments (isotherms and kinetics) and column experiments were conducted to evaluate its sorption performance toward Pt(IV). It was clearly revealed in column experiments that the PEI-coated waste PAN textile (WPAN) has fast kinetics and good performance for Pt(IV) recovery.

“…Pseudo first order kinetic models have often been applied on experimental adsorption kinetic results to study whether the adsorption of metal ions dominated by a physical or chemical sorption mechanism. The Kinetics of the studied Phragmites were subjected to the linearized forms of the Pseudo first order equation [25,26] and a linear fit of log (Q e − Q t ) versus time (t) is observed in Figure 9b:…”

Removal of Lead and Cadmium Ions from Aqueous Solution by Adsorption on a Low-Cost Phragmites Biomass

et al. 2019

In recent years, the interest in waste water treatment increased to preserve the environment. The objective of this study is the removal of lead and cadmium ions from aqueous solution by treated Phragmites biomass (TPB). TPB was characterized by using Fourier transform infrared spectroscopy (FTIR) and energy dispersive X-ray analysis (EDS) which indicates the presence of functional groups that may be responsible of metal adsorption such as hydroxyl, carbonyl, sulfonate and carboxylate. Characterization by scanning electron microscopy (SEM) and surface area analysis using the Brunauer–Emmett–Teller method (BET) illustrated that TPB is nonporous with a small surface area. The influences of various experimental factors were investigated; the proposed method recommended the extraction of Pb+2 and Cd+2 metal ions by TPB at pH 5.0. A contact time of 60 and 45 min was required for the adsorption 50 mL (50 ppm) Pb+2 and Cd+2 respectively to reach equilibrium when 0.10 g TPB was used. The optimum TPB dosage was 0.20 g for adsorption both metal ions when adsorbate solution was 50 mL (50 ppm). Particle sizes of 0.125–0.212 mm showed the best metal ion removal of both metal ions. Thermodynamic study illustrated that both metal ions correlate more with Langmuir isotherm. Furthermore, chemisorption of Pb+2 and Cd+2 on TPB was more likely according to kinetic study data.
