A small automatic system for total phosphorus detection based on absorption photometry using sequential injection analysis technique is realized. Experimental results demonstrate that the automatic detection system has high accuracy and good repeatability with the concentration of total phosphorus at range of 0
0. 5 mg/L
and can be used to detect total phosphorus in I
V class water clarified in national surface water environmental standard. The developed system has the advantages of high-precision of testing results
