“…For the HCl-HNO 3 system, the capacities increase with the HCl concentration increase and HNO 3 concentration decreases. Such behavior was observed previously for about 30 examined ion-exchange resins [4,5,8,12,14,15,20] Table 5. Based on Table 5 the following observations can be made:…”

“…In 0.1 M HCl solution quantitative removal of Pd(II) is obtained after only 15 min, whereas for Pt(IV) and Au(III) longer time is needed. Compared to other studies this time is very short and similar to that obtained for the Dowex MSA-1 [14], Lewatite TP-220 [12], and Purolite A-830 [15] ion exchange resins.…”

“…The other parameters were following: lamp current 10 mA-Pd(II); 4.0 mA-Au(III); 7 mA-Pt(IV), slight width 0.2 nm-Pd(II), Pt(IV); 1.0 nm-Au(III), acetylene flow 2 dm complexes. More information about the Pd(II), Pt(IV), and Au(III) complexes species can be found in [2,12,13].…”

“…The initial Pd(II) concentrations were in the range from 100 to 6000 mg/L (in 0.1 M HCl). The Langmuir and Freundlich isotherms described in [12,15] were applied. The Langmuir and Freundlich parameters were obtained by plotting C e /q e versus C e and ln q e versus ln C e , respectively, and the data are provided in Table 3.…”

Ion exchange is an alternative process for uptake of noble metals from aqueous solutions. In the present study, the sorption of Pd(II), Pt(IV), and Au(III) ions from aqueous solution was investigated by using Purolite A-400TL (strongly basic anion exchanger, gel, type I) in a batch adsorption system as a function of time (1 min-4 h). Initial Pd(II) concentration (100-1000 mg/L), beads size (0.425-0.85 mm), rate of phases mixing (0-180 rpm), and temperatures (ambient, 313 K) were taken into account during the Pd(II) sorption process. Moreover, the column flow adsorption study was carried out, and the breakthrough curves were obtained for Pd(II) ions. The equilibrium, kinetic, desorption, and ion-exchange resin reuse studies were carried out. The experimental results showed that Purolite A-400TL-the strongly basic anion-exchange resin could be used effectively for the removal of noble metal ions from the aqueous medium. The kinetics of sorption process is fast and the resin could be reused without reduction of capacity (three cycles of sorption-desorption, the reduction of capacity is smaller than 1 %). The column studies indicated that in the dilute acidic solution (0.1 M HCl) the working anion exchange capacity is high (0.0685 mg/cm etc. The highest % of Pd(II) desorption was obtained using thiourea, acidic thiourea, sodium hydroxide, and ammonium hydroxide as eluting agents (%D1 was in the range of 23.9-46.9 mg/g).

A B S T R A C TThe potential of economically cheaper Tribulus terrestris was assessed for iron adsorption from aqueous solutions. The effects of pH, Contact time, sorbent dose, initial metal ion concentration and temperature on the uptake of iron were studied in batch process. Chemical treatment processes are ineffective and produce large quantity of sludge which requires further treatment. A simple and efficient treatment process for the removal of heavy metals is essentially required. Maximum iron removal was observed at pH 6 with adsorbent dosage of 0.6 g. The adsorbent data has been correlated with Langmuir and Freundlich adsorption models. FTIR and SEM before and after adsorption were recorded to explore the number and position of the functional groups available for iron binding onto the studied adsorbent and changes in surface morphology. The maximum percentage of iron removal was achieved at 87%. The results revealed that iron is considerably adsorbed on Tribulus terrestris and it could be economical method for the removal of iron from aqueous solutions. Pseudo second order model explains the iron kinetics more effectively.
