Short summary
Imogolite-type nanoparticles (ITN), consisting of imogolite, allophane and their precursors, are important sorbent materials for the cycling of phosphate, arsenate and other oxyanions, at least in forest soils and probably also in other environments.
However, we know little about ITN compared to other important natural nanoparticles e.g. Fe oxides.
Our main purpose is to increase the knowledge on the surface chemistry, ion adsorption properties, and biogeochemical significance of ITN. Techniques employed include ATR-FTIR, TEM-EDX, Single-particle ICP-MS, EXAFS spectroscopy, batch experiments and surface complexation modelling.
