“…These data are in agreement with the literature, since the heavy metal adsorption takes place in a narrow pH range [47][48][49]. In the case of adsorption of Cu 2+ species, it has been reported that Cu adsorption increases at higher pH values [24,47].…”

Featured Application: In this work, an inexpensive and available material, as volcanic glass, is used to absorb metals from wastewater and then it is used to the separation of light liquid-olefins.Abstract: Raw porous volcanic glass from Cuba was used as an adsorbent for Cu 2+ removal from dyes after activation with an acid solution. After Cu 2+ adsorption, it was also evaluated its capacity to separate n-paraffins from a mixture by inverse gas chromatography (IGC), and the results were compared with those obtained with bare volcanic glass without copper. The main goal of this work is to highlight the great applicability of natural volcanic glass, which can be reused without pretreatment as an adsorbent. The results from copper adsorption were quite promising, considering the availability and low cost of this material; the sample without acid treatment turned out to be the most adequate to remove copper. Moreover, the results from IGC revealed that the separation of paraffins from the mixture was achieved with both bare volcanic glass and glass containing Cu, although greater heat adsorption values were obtained when copper was present in the sample due to the stronger interaction between paraffin and copper. The high availability and low cost of this porous material make it a potential and attractive candidate to be used in both heavy metal removal and paraffin separation for industrial purposes.

“…Compared with chemical precipitation and electrochemical methods, ion exchange or adsorption on a solid sorbent appear to be more effective methods for the removal of low concentrations of heavy metal pollutants and radionuclides [2,[4][5][6][7]. However, the removal of cobalt from aqueous solutions by universal cation ion exchangers or adsorbents (e.g., activated carbon, ion exchange resin) can be quite costly [5,8]. Hence, the use of various low-cost sorbents for removing cobalt is a subject of considerable interest in today's society.…”

“…Different raw materials on carbonate and aluminosilicate base can be used to elimination of heavy metals from contaminated water [8][9][10][11][12][13]. Perlite is considered a suitable sorbent and immobilizer of metal cations, nanoparticles and microorganisms [10][11][12][13][14][15][16][17][18][19]. As the works showed [11][12][13][14][15][16][17][18][19][20] removal of pollutants from water by perlite depends on the properties: pH value, kind of ions and their concentration in the solution, temperature surrounding.…”

“…The fact that perlite shows negative zeta potential is attributable to isomorphic transaction, defects in the crystal lattice and structural hydroxyl groups. The elimination process of metallic ions by perlite from water is most commonly explained by adsorption mechanism with ion exchange [14][15][16]. The low adsorption at pH < 4 can be explained by increasing of the positive charge density on the surface.…”

The expanded perlite was studied as adsorbent for removing of Cu 2+ ion from contaminated water. The test conditions were following: pH = 2 -11; a perlite dosage 0,1 -1 g; ratio solution: sorbent = 20 -500 ml : 1 g; basic concentration of the Cu 2+ ions 0,5 and 5 mg.1 -1 , laboratory temperature. The results showed that the perlite shifts the pH value of solutions which have the pH in region of 4 -9 to neutral region 6 -7. The pH value of solution was adjusted by HCl/NaOH and McIlvaine (citric acid/Na 2 HPO 4 ); and Sőrensen (Na 2 HPO 4 /KH 2 PO 4 ) buffer. Top-tests were carried out with solution adjusted by HCl/NaOH. The removing of Cu 2+ ions from water relates with the basicity of aqueous solutions. If the ratio of perlite to solution with Cu 2+ concentration of 5 mg.l -1 is 1 g : < 40 ml the removal of Cu 2+ ions from solution rapidly increases in interval of pH from 4,5 to 5,5 and at pH ≥ 6 achieves a maximum. For these properties perlite is used as fireproof insulating material, sorbent of oil, filter material and vitrificator [1][2][3][4][5][6][7]. The more water contamination grows in nature, the more interest is focused at sorbents and immobilizers of surface-active substances. Different raw materials on carbonate and aluminosilicate base can be used to elimination of heavy metals from contaminated water [8][9][10][11][12][13]. Perlite is considered a suitable sorbent and immobilizer of metal cations, nanoparticles and microorganisms [10][11][12][13][14][15][16][17][18][19].
