| Abstract: | Benzene removal
efficiency of granular activated carbon in indoor/poorly ventilated rooms has
been studied. Commercially available coconut shell based granular activated
carbon is used for this purpose. The benzene removal efficiency of carbon
dosage of 50-100mg and benzene concentrations of 3-12 µg at environmental
parameters, viz. temperature (25-45ºC) and pressure (10-100 mbar) has been
studied. Response surface methodology is used for the optimization of
environmental parameters. The maximum percentage removal of 45-48 is achieved
at 35ºC. It shows that the physisorption plays main role in benzene removal.
The samples are analysed using GC. |
