Abstract
|
|
|
This study has been designed to conduct isotherm tests of Trichloroethylene with activated carbon coated with TiO2, ZnO and TiO2, ZnO and then to analyze the effect of the removal of Trichloroethylene using activated carbon coated with 3,063
㎍TiO2/g
AC.
@ES The results are as follows:
@EN 1. Adsorption capacity of activated carbon coated with 3,063㎍ TiO2/g AC was improved. It is reflected not only as an increase in Freundlich adsorption capacity value (k) but also as a decrease in Freundlich exponent value (1/n)
2. Adsorption capacity of activated carbon coated with 38,718㎍ZnO/g AC was improved. It is reflected not only as an increase in Freundlich adsorption capacity value (k) but also as a decrease in Freundlich exponent value (1/n).
3. Adsorption capacity of activated carbon coated with TiO2, ZnO was not improved.
4. Using activated carbon coated with 3,063㎍ TiO₂/g AC, the concentration of TCE by UV light was not changed. It is because of the effect of background organic material(methanol).
5 Using activated carbon coated with 3,063㎍ TiO₂/g AC,. The concentration of CI-by UV light was not changed. It is also because of the effect of background organic material(methanol).
