| Summary: | One of the problem caused by the increase of human population is worse level of water
pollution. One of dangerous components of pollutant is heavy metals. Several methods have
been used for handling such a pollutant, including the separation method by membrane. In
this research, analcime zeolite composite membrane was fabricated for Pb2+ and Cu2+
separation. In this research, the separation carried out could be considered as microfiltration
based on the membrane’s pore size. Analysis toward permeate and feed phase confirmed a
higher rejection coefficient of the membrane towards Pb2+ (92,66%) and a moderate one
towards Cu2+ (67,10%). However, their concentration in the feed phase decreased as well.
This might be interpreted that there was a phenomenon of absorption of Pb2+ and Cu2+ into
the membrane’s pores. Thus, an experiment of membrane immersion in a mixture of aqueous
Pb2+ and Cu2+ was carried out to determine Pb2+ and Cu2+ content in membrane’s pores. It
was found that 0.22% Pb2+ and 11,04% Cu2+ were absorbed into the membrane matrix. |
