摘要
提出了磷酸氢二铵和磷酸二氢铵磷肥产品中砷含量的测定方法.磷肥样品经王水消解,并滴加盐酸反复蒸发后,获得待测试样溶液.用电感耦合等离子体发射光谱仪进行测定,砷含量测定结果相对偏差(RSD)小于10％,符合分析检验要求.
Abstract
A method for determining the arsenic content in diammonium dihydrogen phosphate and diammonium dihydrogen phosphate phosphate fertilizer products was proposed.The phosphate fertilizer sample was dissolved in aqua regia and evaporated repeatedly with hydrochloric acid.The test sample solution was obtained and measured using an inductively coupled plasma emission spectrometer.The relative deviation(RSD)of the arsenic content determination result was less than 10％,which meets the requirements of analysis and inspection.
