Comparative study of low-cost fluoride removal by layered double hydroxides, geopolymers, softening pellets and struvite

Excessive F^- 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^- uptake: layered-double-hydroxides (LDHs), geopolymers,...
