Biosorption of Cu2+ from aqueous solution by alkali modified waste jute woven fabrics
Апстракт
Waste jute fabrics (raw and alkali modified), acquired as waste from different industries
were used as an efficient biosorbent for removal of Cu2+ ions from aqueous solution. All
woven jute fabrics (raw as well as alkali modified) were characterized by determination of
their chemical composition and amount of carboxyl groups. The effect of solution pH,
contact time and initial metal ion concentration on the biosorption were studied. The alkali
modifications lead to hemicelluloses removal and an increased amount of carboxyl groups.
The maximum biosorption capacity for Cu2+ was observed at pH 5.5. Concerning the contact
time, more than 80% of total Cu2+ uptake by the raw jute fabric was removed within 1 h. On
the other hand, in the case of alkali modified jute fabrics, between 70-75% of the total Cu2+
uptake was removed within 3 h. Increased initial ion concentration from 10 to 20 mg/l
caused an increase in the total uptake capacity of alkali modified jute fabrics for 42-55%. I...t
was found that the biosorption properties of waste jute fabrics are predominantly influenced
by the amount of carboxyl groups, while fabric chemical composition (i.e. hemicelluloses
content) has a secondary role in the biosorption of Cu2+ ions. The best biosorption
performance possesses alkali modified jute fabric with 58% higher amount of carboxyl
groups; its total uptake capacity towards Cu2+ ions (at 20 mg/l) is about 2 times higher
compared to the raw jute fabric.
