Mn-feroxyhyte: The role of synthesis conditions on As(III) and As(V) removal capacity
Tresintsi, S.; Simeonidis, K.; Mitrakas, M. (2014)This study evaluates the critical parameters of synthesizing nanocrystalline tetravalent Mn-feroxyhyte, a single-phase arsenic adsorbent equally efficient against As(III) and As(V). The production of such Fe/Mn oxy-hydroxides ... -
A novel approach for arsenic adsorbents regeneration using MgO
Tresintsi, S.; Simeonidis, K.; Katsikini, M.; Paloura, E. C.; Bantsis, G.; Mitrakas, M. (2014)An integrated procedure for the regeneration of iron oxy-hydroxide arsenic adsorbents by granulated MgO is proposed in this study. A continuous recirculation configuration, with a NaOH solution flowing sequentially through ... -
The role of SO42- surface distribution in arsenic removal by iron oxy-hydroxides
Tresintsi, S.; Simeonidis, K.; Pliatsikas, N.; Vourlias, G.; Patsalas, P.; Mitrakas, M. (2014)This study investigates the contribution of chemisorbed SO42- in improving arsenic removal properties of iron oxy-hydroxides through an ion-exchange mechanism. An analytical methodology was developed for the accurate ... -
Tetravalent Manganese Feroxyhyte: A Novel Nanoadsorbent Equally Selective for As(III) and As(V) Removal from Drinking Water
Tresintsi, S.; Simeonidis, K.; Estrade, S.; Martinez-Boubeta, C.; Vourlias, G.; Pinakidou, F.; Katsikini, M.; Paloura, E. C.; Stavropoulos, G.; Mitrakas, M. (2013)The development of a single-phase Fe/Mn oxy-hydroxide (delta-Fe0.76Mn0.24OOH), highly efficient at adsorbing both As(III) and As(V), is reported. Its synthesis involves the coprecipitation of FeSO4 and KMnO4 in a kilogram-scale ...
