Aquatic weeds are widely used as animal feed in developing countries. However, information about element bioavailability from these plants is lacking. A combination of an in vitro method [physiologically based extraction test (PBET)] and an in vivo feeding trial was used in this study to investigate potential element bioaccessibility and estimated bioavailability of Pistia stratiotes (PS). Cu, ...
A sensitive method is described for the on-line determination and preconcentration of nickel using the coupling of a flow system (continuous flow and flow injection) with transversely heated electrothermal atomic absorption spectrometry. The method is based on the volatilization of nickel as nickel tetracarbonyl and its trapping on a graphite surface. The carbonyl generation is optimized by usi...
