Resum
A capillary electrophoresis (CE) method to determine metal-cyano complexes from leaching solutions of automobile catalytic converters has been developed. The separation and detection conditions have been optimized and analysis times up to 20 min and metal detection limits in the ppb range have been obtained. The CE analysis of leaching solutions from different converters allowed the determination of Fe(II)-, Cu(I)-, Pd(II)-complexes and NO3-. On the other hand, adsorption onto activated carbon i...
