The method of testing formic acid,acetic acid,and propionic acid was established using ion chromatog-raphy.The standard recovery rates of formic acid,acetic acid,and propionic acid were 95.5% ~104.2%, 94.0%~105.8%,and 93.5% ~103.8% respectively.The method is simple,flexible,reliable,and prompt with fewer reagents than ordinary methods.It doesn't need any pretreatment either.
