摘要： 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.
