PENGGUNAAN MEMBRAN KITOSAN UNTUK MENURUNKAN KADAR LOGAM KROM PADA LIMBAH INDUSTRI PENYAMAKAN KULIT
Abstract: Membrane made of
chitosan from shrimp shell can be used to reducea heavy metal chromium (Cr)
content in leathertanning industry waste by adsorption. The membranes were
manufactured from chitosan with concentrations of 2, 3, and 4wt%, respectively.
In addition, glycerol was added during membrane manufacturing as an additive to
increase the permeability properties. The results showed that themembrane with
2% chitosan without glycerol gave the best adsorption performance. However,
increased the chitosan concentration showed a negative effect to the membrane
performance in adsorbing the chromium due to chitosan solubility limitation in
the acetic acid. However, the use of glycerol did not improve the adsorption
performance. This was due to hydrophilic property of the glycerol.
