“…Thus, at C 2 to C 4 levels pozzolan showed the highest Cl removal efficiency (from 61 to 68 %), with values consistent to those previously reported (Al-Rawajfeh et al 2013), followed by limestone (from 16 to 45 %). Al-Rawajfeh et al (2013), studying Cl sorption onto pozzolan, argued that at low added NaCl concentrations, Cl sorption may be independent of the added NaCl concentration because of number-of-ions to available-surface-area ratio is low. However, at higher added NaCl concentrations the available sorption sites decreases, which may explain the Cl sorption becomes dependent on the initial concentration.…”

“…Natural pozzolan is a black or red igneous rock whose porosity and cellular texture confers a high potential retention capacity. Pozzolan has been traditionally employed as building material (in cement and concrete), but it has revealed high suitability for removing Cl ions (Al-Rawajfeh et al 2013) and chlorinated benzenes (Cottin and Merlin 2010).…”

De-icing salt (NaCl) application is a common practice during winter road maintenance in northern countries, compromising ecosystem services. Ecoengineering facilities, including reactive filter beds, are becoming an effective strategy for road runoff management. Different materials (anthracite coal, dolomite, limestone, and pozzolan) were tested as reactive media of filter beds. Characterization showed that dolomite has the best physical properties (resistance to fragmentation, porosity) for filter bed construction and maintenance, followed by limestone. NaCl removal efficiency was investigated in batch at different concentrations (150-5000 mg L -1 Cl). Removal efficiency substantially varied depending on the element (Cl or Na), the material, and the added NaCl concentration. At the lowest NaCl concentration, Cl removal was higher onto anthracite (48 %) and dolomite (59 %); but greater Na removal was reached onto limestone (54 %) and pozzolan (67 %). At higher concentrations, Cl removal was similar (anthracite), decreased (dolomite), or increased (limestone, pozzolan); and Na removal increased (anthracite) or decreased (dolomite, limestone, pozzolan). Parallel experiments at 4°C showed lower NaCl removal, anthracite being the most efficient. Practical applicability was evaluated in columns using synthetic runoff solution (NaCl and metals). NaCl removal efficiency was much lower in column assays with respect to batch. The highest NaCl removal was reached onto dolomite, followed by limestone. Metals were successfully removed, generally remaining over time in a wide range (41-89 % Cd, 78-97 % Ni, 44-88 % Cu, and 3-83 % Zn) depending on the material, being pozzolan the least efficient. Further studies including a combination of materials would be of high interest.

“…17,[20][21][22][23][24][25][26][27][28] Meanwhile, the negative ion charge makes it possible for Cl(−I) to be removed through ion exchange approach using ion exchange resins or layered double hydroxides (LDHs). [29][30][31][32][33][34][35] In addition, because of the extremely high stability of Cl(−I), removing Cl(−I) without any changes to its ionic form through physical separation methods, including electrosorption, electrodialysis, evaporation concentration and solvent extraction, [36][37][38][39][40][41][42][43][44][45][46] has also been widely studied.…”

Abstract. Aluminium (Al) based in-situ metal matrix composites (MMCs) have better properties and performance compared to ex-situ MMCs. In this research, aluminium-copper (Al-Cu) alloy was reinforced with 3 and 6wt.% titanium diboride (TiB 2 ). Al-MMCs has been fabricated with salt route reaction process at 800 °C via potassium hexafluorotitanate (K 2 TiF 6 ) and potassium tetrafluoroborate (KBF 4 ) salts. Hardness vickers tester and Gamry-Electrod Potentiometer were used to characterize the hardness properties and to determine the corrosion rate of Al-Cu alloys. From results obtained, increased TiB 2 contents will increase the hardness of Al-Cu alloys. Increased of TiB 2 contents also will increase the corrosion rate of Al-Cu alloys. Al-Cu with 3wt.%TiB 2 gave the good properties of corrosion when the wear rate recorded the lowest value compare to Al-Cu alloy itself and 6 wt.% TiB 2 . The corrosion rate of Al-Cu with 3wt.TiB 2 was 16.15, while Al-Cu and Al-Cu-6wt%TiB 2 were 22.5 and 58.7 mm/y respectively.
