Direct inverse voltammetric determination of Pb, Cu and Cd in some edible oils after solubilization
1995
The direct determination of traces of certain heavy metals in oils is possible after treatment of the methanolic sample solution with Lumatom (tetramethylammoniumhydroxide). For the inverse voltammetric determination, a flow through cell with a mercury film electrode is used. The results for the determination of Cu and Pb in some edible oils after solubilization agree well with those obtained using wet oxidative high pressure ashing.
Selective and sensitive determination of copper by stripping voltammetry after medium exchange in a flow-through cell
