Abstract: In this paper, the determination of the trace amount of iron in the phosphate by AASwith graphite furnace atomizer is discussed. It was found that the interference of PO4-3 and some metal for iron can be suppressed by the use of the higher charring temperature (1300℃) and Zeeman effect.After the sample is dissolved, it can be measured directly, without using any way of separation.
