is retained as a stationary phase in the rotating
column, whereas leaching solutions of mineral acids, electrolytes
(salts), and complexing agents are successively pumped through. A
flow-through hyphenated analytical method has been proposed
that enables not only the accelerated and efficient fractionation of
trace elements species in environmental solids to be achieved but
allows real-time studies on the leaching process to be made. Elements were determined in the effluent of RCC on-line by inductively coupled plasma atomic emission spectrometry
