Bisphosphonate modified mesoporous silicon for scandium adsorption

Scandium has several applications in advanced technology, but its wider utilization is restricted by the limited supply. Scandium exists in low concentration in ores and, therefore, the conventional extraction methods are difficult, uneconomical, and often hazardous to the environment. Adsorption is more sustainable method to extract scandium, because of low energy consumption and scalability. However, selectivity and stability of adsorbents are...
