| Abstract: | Metals fixed by seric proteins of crustacean decapods were determined by non-flame (Cu, Pb, Fe) or flame (Zn) atomic absorption spectrometry after separation of the proteins by electrophoresis. The electrophoregrams were cut into 5 mm fractions and each fraction was dissolved in nitric acid. The solutions thus obtained were analyzed. Metal concentrations of the order of a few ppm in protein fractions were covered. |
