摘要
Abstract
This article describes determination of trace harmful heavy metal-lead element in phosphate rock and concentrate rock with flame atomic absorption spectrometry method.The relative standard deviation of this method is 3.1～14.2%,recovery rate is 90%～104%,the sample detection limit is 0.0008%.The method is accurate,fast,easy,make up for method of determination lead in phosphate rock.It provides effective control method for production of feed additives and fertilizers and so on.关键词
