The industries of leather-tanning, mining and textile dyeing, generate large amounts of
chromium-containing wastewater. Hexavalent Cr(VI) is highly poisonous and extremely
mobile in the surface-water and groundwater in a broad pH range and therefore it has
been identified as a potentially carcinogenic substance. The aim of the presented work
was to develop cellulose-based membrane functionalized with magnetite, which could
be used as an efficient adsorbent for the removal of hexavalent chromium Cr(VI) ions
from aqueous solutions. Cellulose-based filter (CF) was functionalized with magnetite
in three-step process. In the first and second step CF surface was modified using
an ethanolic solution of (3-aminopropyl)triethoxysilane (APTES), and
diethylenetriaminepentaacetic acid dianhydride, respectively. The introduction of amino
and carboxylic groups provided successful precipitation of magnetite in the third step.
The obtained cellulose-magnetite membrane (CelMag-M) was charact...erized by FTIR
and SEM analysis. Adsorption of Cr(VI) onto CelMag-M was studied using batchadsorption
test. Under optimum pH conditions, the maximum experimental adsorption
capacity of CelMag-M for Cr(VI) was found to be 111.2 mg g–1. The adsorption process
was endothermic, the equilibrium adsorption data could be best fitted to the Langmuir
adsorption isotherm model and kinetics was in agreement with the pseudo-second-order
rate equation.
