摘要
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.关键词
