T his paper aims to
investigate the removal
of copper ions from aqueous
solutions using combined
methods; the adsorption
Cu2 + ions onto natural clay
as a low-cost adsorbent and
reverse osmosis method.
During experimentation
batch technique is applied
and equilibriumadsorption
parameters, [Qm=95.24(mg/g) and
b=0.0032(L/mg), Kf=1.91(mg/g)
andn=1.21(L/mg)],were found
using theLangmuir and Freundlich
isotherms. The results fit better
with the Freundlich isotherm.
Regarding the adsorption
kinetics, pseudo first order and
pseudo-second-order models
are examined and it is found
that the adsorption of copper
ions onto natural clay nature
obeys pseudo-second order.
Heterogeneous asymmetric
reverse osmosis membranes
made from a blend of cellulose
acetate, powdered coal and
powdered bentonite prepared
from the composition of
casting solvent have been
studied in the relatively low
pressure 17.63x105Pa. The
analysis and conclusions
reached in this work show that
heterogeneous asymmetric
reverse osmosis membranes
have better properties
compared to asymmetric
cellulose acetate membranes.
Biography
Makfire Sadiku-Hasani is an
Assistant Professor in the
Department of Chemistry at
the University of Prishtina.
From 1997 to 2013 she
worked as a teaching
assistant. She was promoted
to Assistant Professor in
2013. She received her B.S.
and M.S. from the University
of Prishtina. She received
her Ph.D. in the field of
Superficial Phenomena from
the University of Tirana in
2012. Recently her research
has focused on the practical
use of clay for the adsorption
of various contaminants from
different mediums and the use
of clay as an addition to the
formation of heterogeneous
reverse osmosis membranes.
