A high performance liquid chromatographic analysis for the simultaneous determination of ammonia, nitrite, nitrate and other anion compounds in the environmental samples has been developed.<BR>The method is based on the separation of nitrite, nitrate and sulfate from cation using anion exchange column for ion chromatograph, and detection of ammonia by indophenol reaction.<BR>In the flow pathway of HPLC carrier, anion compounds are detected by conductivity detector, and postcolumn derivatization using spectrophotometric detector at 640 nm of wave length was determined ammonia.<BR>An ammonia can be detected selectivity in water at 0.01 ppm concentration.<BR>It was appllied determining of chloride, nitrite, nitrate, sulfate and ammonia in the environmental water samples such as lake, river, wastewater plant and rain by this method.
