Abstract (english)

Hydroxamic cellulose fibre with a high content of hydroxamic
groups was prepared. The extent of hydroxamation was established
by determination of nitrogen. The sorption capacity of the fibre
was estimated to be 2.1 mekv/g. The hydroxamic cellulose fibre
represents a selective sorbent for fast preconcentration of traces of
ions. The effect of the mass of the sorbent, salt effect and contact
time on sorption, were studied by using 5-30 mg of the hydroxamic
cellulose in 25 ml from 1 to 10 ppm iron(III) solutions.
Preliminary results show that hydroxamic cellulose may be used
in environmental analytics.
