Calcium-zinc and calcium-cadmium exchange in suspensions of various types of clays

R Van Bladel, H Halen, P Cloos - Clay Minerals, 1993 - cambridge.org
Calcium-cadmium and calcium-zinc exchange equilibria were studied at 20C and constant
ionic strength (0·015) on four clay minerals, viz. montmorillonite, bentonite, illite and …
