Abstract
The uptake behavior of Co2+ was Studied in zeolite ZSM-5 samples. The Co2+ uptake decreased in this zeolite as ethylenediamine was added, as opposed to the results found in previous experiments in which the Co2 + uptake increased in zeolite Y and NaA. Spectroscopic and magnetic st udies suggested the presence of two high-spin species in Co-ZSM-5 and a high-spin and radical species, mainly in Co-ZSM-5, which was exchang ed in the presence of ethylendiamine.
