Abstract
A new method using solid phase extraction with nanosized hydroxyapatite
for solving interference from nitrate ions on oxalic acid in reversed phase
high performance liquid chromatography (RP-HPLC) was developed. The optimum
experimental conditions for the separation and determination of oxalic acid
were studied. After the interference was eliminated, oxalic acid was determined by
RP-HPLC at the optimum chromatographic conditions with an average recovery
ranging between 94.8% and 99.3%, and the relative standard deviations were less
than 3.0%. This method was successfully applied to determine the oxalic acid in
the xylem saps of tomato.
