Aktivitas Antibakteri TiO2-Anatas Terdadah -Vanadium dan -Kromium
Abstract: Samples of vanadium-
and -chromium doped TiO2-anatas have been conducted antibacterial activity
against the bacteria Escherichia coli (E. Coli). The minimum kill concentration
(MBC) against the bacteria of E. Coli is determined by liquid dilution method. The antibacterial
activity test of 0; 2.3; 3.3; 4.9% wt. vanadium doped TiO2-anatas and 0; 1.1;
3.9; 4.4% wt. chromium doped TiO2-anatas have been performed against bacteria
of E. Coli in the absence of light (dark). The test results indicate that the
presence of 3.3 and 4.9 in %wt. vanadium-TiO2-anatas are able to inhibit the
growth of bacteria E. Coli, contrary all chromium doped TiO2-anatas are not
able to inhibit the growth of bacteria of E. Coli.
