Hudson, M.J., Jackson, D.B., Ward, J.L., Chinn, M.J. and Stockenhuber, M. (2004) Peroxydisulfate in MCM-48 silicas: powerful and clean materials for the removal of toxic gases. Journal of Materials Chemistry, 14 (7). pp. 1180-1186. ISSN 0959-9428 doi: 10.1039/b314426g

Abstract/Summary

Sodium persulfate introduced into ordered MCM-48 silicas is described. The resulting materials are compared with existing activated carbon-based systems and MCM-48 containing transition metals such as Cu(II) and Cr(VI) for the decomposition of hydrogen cyanide and cyanogen. MCM-48 materials containing sodium persulfate alone improve on the protection offered by benchmark activated carbon systems and MCM-48 materials containing Cu(II) and Cr(VI), without the health risks associated with these metal ions.
