摘要
Abstract
The sample is dissolved in ammonia water and hydrogen peroxide,and its emission intensity is measured at 207.911 nm on the inductively coupled plasma atomic emission spectrometer in hydrochloric acid and nitric acid medium.The mass fraction of tungsten in roasted molybdenum concentrate is calculated.The experiment investigated factors such as sample dissolution method,ammonia dos-age,nitric acid dosage,and molybdenum matrix interference.The precision of the method is not greater than 3.3%,the recovery rate is between92%and99%,the detection limit of the instrument is 0.000 5%,and the determination range is 0.005 0%to 0.50%.关键词
