“…In the case of sepiolite, the intense diffraction peak at 2θ (º) = 7.28 (d 001 = 12.1 Å) points out its high crystallinity, confirmed by the appearance of other characteristics signals between 20 and 40° [41]. The signal located at 60.86° (1.52 Å) demonstrates the existence of a trioctahedral clay mineral, i.e.…”

“…In the case of adsorption of Cu 2+ species, it has been reported that Cu adsorption increases at higher pH values [24,47]. Under these activation conditions, the leaching of volcanic glass must be discarded, since it requires stronger conditions [50,51]. …”

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.
