Abstract

This paper correlates the structure/surface chemistry and removal performance of the three Mg-Al-CO3 Layered Double Hydroxides (LDH) prepared by different synthetic methods: alkoxide sol-gel (commercial product), hydrothermal precipitation and alkoxide-free sol-gel methods. The LDHs differed considerably in porosity and surface chemical properties, hydration, speciation which was strongly reflected in their removal performance to five toxic anions. One of these materials always involves its interlayer carbonate in the removal mechanism which correlates well with its exceptional removal performance. This LDH also keeps its interlayer distance unchanged after hosting toxic anions in its interlayer space which indicates its stability in water.
