Table 1 Indexes and chemical composition of obtained samples in system M–Ca2+–NO3–CO32−–PO43− (M–Na, K) (at fixed molar value of Ca/P = 1.67 and different ratio CO32−/PO43−) after heating to 400 °C

From: Immobilization of cesium from aqueous solution using nanoparticles of synthetic calcium phosphates

Samples index M Molar ratio CO32−/PO43− in initial solution M (wt%) Ca (wt%) P (wt%) C (wt%) (Ca + M)/(P + C) (mol)
