APPLICATION OF NANO POROUS CARBON FOR THE UPTAKE OF PHENOL AND 2-CHLOROPHENOL AS BISOLUTE FROM WATER

Nano porous activated carbon prepared from coir pith using ZnCl2 (ZnCPC) was investigated to find the feasibility of its application for mixture of phenol and 2-chlorophenol in aqueous solution through sequential adsorption/desorption process by HPLC C-18 column. Nano porous carbon was characterized using standard physio-chemical methods, BET surface area, pore diameter, SEM and XRD studies. Adsorption of 2-CP in bisolute systems showed that 2-CP were adsorbed preferentially, but phenol was adsorbed competitively. This result was further confirmed by η1 and η2 values obtained from extended Langmuir model. The cost of ZnCPC is economically effective compared to commercial activated carbon.
