Research Progress in Application,Production Technology and Analytical Methods of High Purity Phosphate

In recent years,because of the increased demand for high purity phosphate,such as food grade,electronic grade,metaloxide-semiconductor grade (MOS reagents),it is significant to develop and improve the production technology and to establish the technical indicators and analytical methods of phosphate.In this paper,the application,main production and purification technology of high purity phosphate were firstly reviewed.And then,we compared and commented the technical indicators and analytical methods of phosphate at home and abroad.In most of cases,potassium dihydrogen phosphate (KH2PO4) was used as an example to illustrate.
