3.3. The relative concentration and chemical state change of different zinc sources in intestinal wall As could be seen in Fig. 5, according to zinc absorption the most amount specific region of m-XRF mapping deter-mined m-XAFS spectra. The m-XAFS spectra of zinc element
in the greatest absorption specific are as for zinc sources of ZnSO4,ZnMet,ZnLys were basically the same in the intestinal wall. The shapes of the former absorption curves and curves behind the absorption peak were similar for the three zinc sources. Sources indicating that organic and
in organic chemical state of zinc were similar and absorbed in the greatest concentration in the intestinal wall. K-edge absorption values for organic zinc was greater than for in organic zinc. The relative zinc concentrations resulting
