Abstract

The use of membrane on separation has been widely studied. In this study, the Chitosan-silicapolyethylene glycol (Ch/Si/P) solid membrane is prepared and performed adsorption test for bivalent metal ions, including Pb(II), Cu(II), and Cd(II), and Rhodamine B dye in textile waste water. The Ch/Si/P composite membrane is made by mixing of chitosan, silica (extracted from ash hulk) and polyethylene glycol with ratio 1: 0.8: 0.5 (w/w). The performance of membrane is carried out using dead end method. The result shows that membrane has a heteregenous and very tight structure. On the other hand, commercial membrane shows a fibrous structure. The rejection test shows that the selectivity of Ch/Si/P solid membrane increases from Cu(II)> Cd(II)> Pb(II)> Rhodamine B. In comparison, the commercial membrane shows the selectivity in the sequence of Rhodamine B > Pb(II) > Cd(II) > Cu(II). It is clearly observed that Ch/Si/P solid membrane for bivalen metal ions is better than commercially available, and it indicates that functional group spread on the surface acts as a binding site.
