Maity A, Mukherjee I: Liquid chromatographic determination of iprovalicarb in cabbage and soil. J AOAC Int. 2004 Jan-Feb;87(1):157-61.
A method was developed for the determination of iprovalicarb, a new carbamic acid-amino acid fungicide, by liquid chromatography with UV detection. The method uses a reversed-phase C18 column with lambdamax at 215 nm and methanol-water (72 + 25, v/v) as the mobile phase. Cabbage head and leaves fortified with iprovalicarb were extracted with acetone. Partitioning of the fungicide into dichloromethane was followed by column cleanup on neutral alumina. Fortified soil samples were extracted with acetonitrile, and the extract was subjected to column cleanup. The average recoveries of iprovalicarb from cabbage head, leaves, and soil were 86.50, 82.0, and 84.3%, respectively, for fortification levels of 1 and 2 microg/g for cabbage head and leaves and 2 and 4 microg/g for soil. |
