Extract

The determination of uranium in low grade ores, some industrial raw materials (e.g. phosphates) and industrial wastes (e.g. coal ashes) at concentrations below 200 ppm Is very important for various reasons, and poses a serious analytical problem. In these materials uranium is often accompanied by elements emitting K lines which interfere with the most intensive U Lα and U Lβ1 lines. The most serious interferences for U Lα lines are from Sr and Rb sometimes present in analysed materials in comparable or excessive quantities. Also Mo, Zr and Y can interfere.
