Exploring the Rapid Determination of Fe,Al,Mg Mass Fractions in Phosphoric Acid by ICP Method
The content of iron,aluminum,and magnesium in phosphate directly affects the quality of phosphate fertilizer products.When the content of Fe,Al,and Mg is too high,it can cause the product to dry and wither.Therefore,exploring the use of inductively coupled plasma e-mission spectroscopy for rapid determination of Fe,Al,and Mg mass fractions in phosphoric acid,with a spiked recovery rate between 95％and 105％,meets the measurement requirements.This method is fast and simple to operate,and can replace chemical titration.
