Development and Validation of an Analytical Method for Determination of Al, Ca, Cd, Fe, Mg and P in Calcium-Rich Materials by ICP OES
Four procedures based on closed-vessel microwave-assisted wet digestion with different oxidative reagents, including HNO 3 (P1), HNO 3 + H 2 O 2 (P2), aqua regia (P3) and Lefort aqua regia (P4), for preparation of calcium (Ca)-rich materials prior to determination of total concentrations of Al, Ca,...
