This article reports on the use of ion chromatography (IC) to investigate extensively the release profiles of both cations and anions and characterize the relationship between composition and degradation for a ternary-based NaO-CaO-PO glass system developed as biomaterials. Studies are carried out on glasses with the formula 45PO-55(CaO-NaO) in deionized water, where = 30, 35, and 40 mol%, using a cumulative release method, where the solution is changed at regular intervals.
