Questions related to Analytical Chemistry

When you use La3+ as a releasing agent for measuring Ca near Phosphate in AAS, should the Phosphate precipitate when adding the La?

Is the Lanthanium added to samples containing Ca and Phosphate to precipitate all the Phosphate or should the La3+ just prevent the Ca to bind to the Phosphate in the flame?

During sample pretreatment using SPE, my obtained LOD was 0.07 ng/mL, but my linear range was from 15 – 1000 ng/mL? How can I explain it?

I do not know if my explanation is right and sufficient, as listed below: In concentration lower than 15 ng/mL, the method definitely had a linearity, but with lower R2, which was inferior to...
