Wei, L. (author), Zietzschmann, F.E. (author), Rietveld, L.C. (author), van Halem, D. (author)Millions of people worldwide are exposed to excessive concentrations of fluoride (F<sup>−</sup>) from groundwater sources. Ca-Al-CO<sub>3</sub> layered double hydroxides (LDHs) have shown promising defluoridation efficiency; however, defluoridation by Ca-Al-CO<sub>3</sub> LDHs is highly pH sensitive. This study showed that simultaneous...journal article 2021

Wei, L. (author), Li, Z. (author), Ye, G. (author), Rietveld, L.C. (author), van Halem, D. (author)Excessive F<sup>-</sup> in drinking water due to natural and anthropogenic activities is a serious health hazard affecting humans worldwide. In this study, a comparative assessment was made of eight mineral-based materials with advantageous structural properties for F<sup>-</sup> uptake: layered-double-hydroxides (LDHs), geopolymers,...journal article 2021

Wei, L. (author), Zietzschmann, F.E. (author), Rietveld, L.C. (author), van Halem, D. (author)In this study, F<sup>−</sup> removal by Ca–Al–CO<sub>3</sub> layered double hydroxides (LDHs) was investigated at environmentally-relevant concentration ranges (2–12 mg/L) to below the WHO guideline, with an emphasis on the effect of LDHs’ modification, as well as the effects of initial F<sup>−</sup> concentration, adsorbent dose, pH,...journal article 2020
