The new method was based on the catalytic effect of trace manganese on the oxidation of leucomalachite green by sodium periodate,the nitrilotriacetic acid as an activator,and used the low Mn Southern Ocean surface water as the reaction medium of the standard working curve.

Malachite green and leucomalachite green in water determined by liquid chromatography/tandem mass spectrometry method;

Determination of the metabolite residues in malachite green and leucomalachite green in sediment by HPLC was established.

A confirmative method was developed with high performance liquid chromatography coupled with electrospray ionization tandem mass spectrometry(HPLC-MS/MS)to simultaneously detect malachite green and leucomalachite green residues in mud.

Determination of Malachite Green and Leucomalachite Green in Fishery Products by HPLC with Dual Wavelength Detector;

Lead(Ⅳ)oxide was on-line to oxidize the leucomalachite green and leucocrystal violet back to the parent after chromatographic separation and prior to detection with Kromasil C_(18) column and acetonitrile-ammonium acetate buffer-glacial acetic acid(58∶14∶28) as the mobile phase.

The residues of malachite green(MG) and leucomalachite green(LMG) was followed for the bottom mud of culturing pond after treatment by MG three times as commercial farm,then,followed depletion and residues of MG and LMG in muscle tissue of japonica eel cultured in pond,witch bottom mud contain MG.
