| Abstract: | The comparison experiment with different sorts of masking agents BaCO3 and EDTA in the determination of boron in the Longan leaf by using azomethine-H method showed that possible ionic interferences can be eliminated by respectively using BaCO3 and EDTA treatment;Ionic interferences in analytes can be adequately eliminated and the precision in the determination of boron is comparatively high if BaCO3 and EDTA are used together. |
