The paper established a flame atomic absorption spectrometry to determine urea iron content, and compared with phenanthroline spectrophotometric method. Two methods were used to sample,a blank value,the recovery test. Experimental results show that the two methods of detection limits were 0. 02 mg/L, the precision of 2 . 2% and 2 . 4%,and the recoveries were 96% ~104% and 96% ~103%,the results are satisfactory.
