| Abstract: | HPLC was used to detect acetate ion.The optimum conditions of the determination were as follows:mobile phase methanol-water(volume ratio 10∶90),flow rate of 1.0 mL/min,pH=1.8,the column temperature 40℃,the detection wavelength 210 nm.The acetate ion was completely present in the form of acetic acid,the peak area fluctuation was small,and the measured value was stable. |
