Abstract:
A Simple method for the determination of micro amount of potassium in cele- stine by aas was studied. The interference of Ba, Sr and Na ions were elimin- ated by adding suitable amounts of th.e restrainer (LaCl3) and masking agent -EDTA sohaion. "The sample was decomposed with HF+HC14,, the solution containing LaCL3 and EDTA was adjusted to 1% hydrocbloric acid medium, the potassium was determined by aas directly.
