“…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).…”

“…Some commercial anion exchange resins such as Sumichelate MC-10 and Diaion WA21 were used, and adsorption capacities were found to be 0.59 and 1.4 mol/kg dry adsorbent, respectively (Alam et al 1998a, b). In another study, adsorption of Rh(III) on ion exchange resin Diaion WA21J was found to be 6.39 mg/g resins (Shen et al 2010). In another work, commercial anion and cation exchangers such as IRN-78, Dowex 1-8, and Dowex 50W were used for the adsorption of Rh(III) from a simulated radioactive liquid waste, and it was found that rhodium is very slightly adsorbed (Lee et al 1999).…”

The clinoptilolite which was modified with sodium and potassium chloride was found to have adsorption capacity for rhodium. To evaluate the adsorption capacity and characteristics, the effects of solution pH, dose of clinoptilolite loading, contact time, temperature, and initial rhodium concentration were investigated in a batch mode. Adsorption was decreased with the increasing temperature for both modified clinoptilolites. The Langmuir and Freundlich adsorption models were used for mathematical description of the adsorption equilibrium. Equilibrium data were fitted to the Langmuir model in the concentrations of 2-60 mg l −1 at 293 and 313 K. Based on the Langmuir isotherm plots, the maximum adsorption capacity value was calculated to be 0.415 mg g −1 at 293 K. Various thermodynamic parameters such as ΔG°, ΔH°, and ΔS°w ere evaluated with results indicating that this system was an exothermic spontaneous reaction and kinetically suited to the pseudo-second-order model.

“…The recent literature has included several methods for the recovery of precious metals (i.e., platinum, palladium, rhodium, ruthenium, osmium, iridium, gold, and silver) from aqueous solutions, such as solvent extraction (Shamsipur et al 2009;Hung et al 2007), ionexchange (Shen et al 2010;Godlewska-Żylkiewicz et al 2000;Shen et al 2011), filtration (Li et al 2013;Trivunac and Stevanovic 2006;Borbély and Nagy 2009), cementation (Aktas 2012;Morcali et al 2013a), and adsorption Kyzas et al 2013;Morcali et al 2013b). Among these methods, adsorption is the most suitable method for the recovery of precious metals due to its low cost, ease in handling, high efficiency, reversibility, and the availability of different adsorbents.…”

Poly(vinyl alcohol)/maleic anhydride/acryloyl thioamide monomer (PVA/MA/ATM) nanofiber membranes (NFm) were synthesized by a combination of UV radiation and an electrospinning technique. The PVA/MA/ATM NFm were characterized by Fourier transform infrared spectroscopy (FT-IR), thermogravimetric analysis (TGA), Brunauer-Emmert-Teller (BET) analysis, scanning electron microscopy (SEM), and energy dispersion spectrometry (EDS). These membranes were used for adsorption-desorption of platinum (Pt(IV)) and palladium (Pd(II)) from a fire assay (FA) leaching waste solution, and the effect of process parameters such as pH of solution, contact time, NFm dosage, temperature, and adsorption isotherms and kinetics studies on the recovery of Pt(IV) and Pd(II) from the waste solution were investigated. The adsorption equilibrium data fit better using the Langmuir model than the Freundlich model. Maximum adsorption capacities, Q max , at 45°C were found to be 69.93 and 112.36 mg/g for Pt(IV) and Pd(II), respectively. The activation energies (E a ) of Pt(IV) and Pd(II) were 27.90 and 20.29 kJ/mol, respectively. The best desorption reagent was a 1.0 M HCl-1.0 M thiourea (TU) solution for both Pd(II) and Pt(IV). Reusability studies showed that the adsorption capacity can remain up to 90 % after five times of usage. This study provides a promising NFm with an effective adsorption property for Pt(IV) and Pd(II) ions.
