Bioactive glasses containing rare earth elements have been proposed as promising candidates for applications in brachytherapy of bone cancer. However, their safety relies on a proper dissolution to avoid radioactive materials in the human body, and desirable bioactive properties to regenerate the bone defect caused by the tumor. In this work, we proposed a new series of sol-gel-derived bioactive glasses containing holmium oxide, based on the system (100-x)(58SiO-33CaO-9PO)-xHoO (x = 1.

The GDE cathode was combined with a BDD anode for decolorization and mineralization of 350 mL of 0.26 mM OII by anodic oxidation with electrogenerated HO (AO-HO), electro-Fenton (EF) and photoelectro-Fenton (PEF) at 100, 150 and 200 mA cm and SSPEF at 150 mA cm.
