Determination of Sulfate in Fertilizer Catalyst by Mobile Phase Ion Chromatography
流动相离子色谱法测定化肥催化剂中硫酸根

This paper describes a method for determination of sulfate in fertilizer catalyst by the use of an active aluminium oxide column for separation and mobile phase ion chromatography. The recoveries of this method were from 99.7% to 102.2%. The coefficient of variation ranged from 2.13% to 5.50%. The results are satisfactory. The method is reliable,simple, accurate and applicable to the determination of sulfate in fertilizer catalyst after a pretreatment by hydrochloric acid.
