Abstract：With the continuous flow of ammonium molybdate spectrophotometric method （HJ 670-2013） and ammonium molybdate spectrophotometric method （GB 11893-89） of total phosphorus in water were determined through experimental analysis， the principle of the two methods and steps for accuracy and precision and other aspects of the comparison. The results show that the two methods can meet the requirements of water quality monitoring汉阳铁厂博物馆， and continuous flow with automatic sampling， rapid analysis speed， low reagent consumption， simple ammonium molybdate spectrophotometry， has the advantages of high detection efficiency， is a good choice for conditions and need to handle large quantities of laboratory samples.
