ABSTRACT
OBJECTIVE:
To establish the ion chromatography for the mass fractions of 9 inorganic anions (fluoride ion,for-mate radical,chloride ion,nitrite radical,bromide ion,nitrate radical,sulfate radical,oxalate radical and phosphate radical) in Ganmao qingre granules.METHODS:
Ion chromatograph was used. The column was Ion Pac AS11-HC with the mobile phase of po-tassium hydroxide solution by gradient elution(concentration30 mmol/L,time15 min),the column temperature was room tem-perature,the volume was 25 μl.RESULTS:
The 9 inorganic anions were basically achieved separation and had good linear relation-ship with r of 0.999 2-0.999 9,respectively;RSDs of precision,stability and reproducibility tests were less than 3.50%. Average re-covery was 92.47%-103.51%(RSD=0.42%-3.41%,n=6),respectively.CONCLUSIONS:
The established method is fast,accu-rate,sensitive and repeatable and can be used for the determination of 9 inorganic anions in Ganmao qingre granules.
