| dc.description.abstract | Eucalyptus alba branches that contain cellulose compounds can be used as
natural materials for the production of activated carbon to make membranes. The
purpose of this study is to make cellulose acetate membranes with the addition of
Eucalyptus alba activated carbon to reduce Fe metal levels. The method used was
carbonization and chemical activation using ZnCl2, followed by the manufacture of
cellulose acetate membranes using phase inversion techniques. Membrane
characterization using X-Ray Diffraction (XRD), morphological analysis using
Scanning Electron Microscopy (SEM), determination of flux, selectivity to Fe metal
using Atomic Absorption Spectrophotometry (SSA) and tensile strength test, so that
Eucalyptus alba membrane was obtained which was able to reduce Fe metal levels,
the initial concentration of 5.723 mg/L could be reduced to 2.995 mg/L; 2.872 mg/L;
and 1.250 mg/L. Reduction of metal concentration Fe was 47.66% respectively;
49,81%; and 78.19%. The flux value of cellulose acetate membrane without the
addition of activated carbon was 0.044 mL/cm2.s and the addition of activated carbon
of 0.5 g 1g 1.5 g was 0.033 mL/cm2.s 0.017 mL/cm2.s 0.011 mL/cm2.s. The mechanical
properties produced were 0.27 Mpa, 0.78 Mpa, 0.120 Mpa, and 0.145 Mpa,
respectively. Based on the data from the research results, it is known that the
membrane with the addition of activated carbon Eucalyptus alba meets the SNI
Surface water quality standards. | en_US |
