Competitive Metal Ion Binding to Datura innoxia Root and Stem Tissue Materials

Dried root and stem tissue samples from the plant, Datura innoxia, were exposed to solutions containing six metal ions, Zn2+, Cu2+, Cd2+, Ni2+, Pb2+, and Eu3+. The resulting binding isotherms were generated using multiline atomic emission spectra of supernatant solutions. Application of regularized regression analysis to these isotherms revealed binding… CONTINUE READING
