摘要
磷酸中铁、铝、镁含量直接影响磷肥产品的质量.Fe、Al、Mg含量偏高时,会导致产品发干发枯.电感耦合等离子发射光谱法,可快速测定磷酸中Fe、Al、Mg的质量分数,加标回收率在95％～105％之间,符合测定要求.该法操作快速、简便,可替代化学滴定法.
Abstract
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.
