The purpose of this work was to find a convenient
separation technique and a convenient carbon material
for removing cyanide from the air on the basis
of a chemisorption process[9,10]. To that purpose,
ACC was additionally activated by chemical impregnation.
In this way, it could be possible to separate
cyanides efficiently by its bonding to an active chemical
agent inside the cloth[ 11-141. Cyanogen, which
is also formed as the product of reaction of metalorganic
compounds with hydrogen-cyanide in the
following step changes into oxamide and one HCN
molecule[15]. The quantities of cyanogen that are
measured during sorption are negligible and were not
taken into account in the course of these testings.
