The previous study reported that BiPbO2(NO3) is one of the most promising candidate materials for removing and immobilizing radioactive iodide. In that case, the solution contained only dissolved NaI and did not contain competing anions. This paper reports the reactivity of BiPbO2(NO3) with iodide ions in simulated radioactive liquid waste. This liquid contains many components, especially highly concentrated NaNO2, Na2CO3 and NaNO3. The obtained results show that BiPbO2(NO3) is useful for removing iodide ion from the simulated radioactive liquid waste but that there is a problem which should be resolved in the future. The problem is that a competing anion, HCO3 −, interferes with the exchange reaction, and only the surfaces of the BiPbO2(NO3) crystals are used for the reaction.

... A number of materials have been researched in recent years for this remit, which have been recently reviewed (Robshaw et al., 2021a). The huge majority incorporate iodine-selective metals into the adsorbent to create the required selectivity, with the most popular metals being Ag, Bi, Cu and Pb (Kodama, 1999;Lefevre et al., 1999;Zhang et al., 2011;Al-Mamoori et al., 2020). Candidates for the bulk phase of the adsorbent have included silicates (Asmussen et al., 2019;Cordova et al., 2020), titanates (Bo et al., 2013;Liu et al., 2015) and metal oxides/hydroxides (Mao et al., 2016;Chen et al., 2018). ...
