Abstract:A reversed phase HPLC was applied for determining 4,4 dimethyl 3 isoxazolidinone. The samples were detected with 60% methanol and water as mobile phase at UV-223nm. The precision was 0.05 with variation coefficient being 0.38%, the recovery 99.24%~ 100.28%. |
Key words:HPLC; 4; 4 dimethyl 3 isoxazolidinone clomazone; determinating; |
