| Abstract: | The conditions of simultaneous determination of formic acid,acetic acid,propionic acid and succinic acid in acid rain with reversed-phase HPLC have been studied.On an ODS column,the effects of mobile phase,flow rate and buffer were systematically investigated.The four acids were determined with UV detector at 215 nm.Recoveries are found to be in the range of 96～103%. |
| Keywords: | RP-HPLC acid rain organic acid and UV detection |
