Removal of aluminum from alkaline aqueous solution by adsorption on Degussa P25 TiO 2 and vermiculite concrete‐supported ferric oxyhydroxide
Abstract The current investigation on aluminum adsorption from an aqueous solution originated from the need to implement a water treatment technology that would decrease the prohibitive aluminum concentrations in the groundwater of the Khibiny Alkaline Massif (Kola Peninsula), which is limiting the...

Abstract The current investigation on aluminum adsorption from an aqueous solution originated from the need to implement a water treatment technology that would decrease the prohibitive aluminum concentrations in the groundwater of the Khibiny Alkaline Massif (Kola Peninsula), which is limiting the use of this water source as a source for the household water supply in the area. TiO 2 and vermiculite concrete‐supported ferric oxyhydroxide (VC) were used as adsorbents to remove aluminum from the alkaline aqueous solution, considering the water‐specific natural conditions of the Khibiny aquifer. The effects of pH, initial aluminum concentration, contact time, adsorbent dose, and ions present in Khibiny groundwater were investigated. The results showed that the adsorption kinetics followed the pseudo‐second order model, and the equilibrium data were described well by Langmuir and Freundlich isotherm models. The aluminum adsorption on TiO 2 exhibited a dramatically higher adsorption rate compared to VC; the adsorption equilibrium was reached in 30 and 240 minutes, respectively, while the maximum TiO 2 and VC adsorption capacities were similar and had values of 6.85 and 6.75 mg g −1 as the results of laboratory tests revealed. It was shown that when these two adsorbents worked jointly the capacity reached 8.28 mg g −1 within 60 minutes at pH 9.0. No apparent significant effects on aluminum removal by adsorbents tested in the presence of SO 4 2− , NO 3 − , and Cl − were observed. The obtained outcomes identify a possible approach and reliable foundation for water treatment technology to solve the problem of elevated aluminum concentrations in the household water of the Khibiny Alkaline Massif area as well as within other locations where the solution of this problem can improve living conditions or industrial technologies. |
