Abstract

This report discusses the research that has been done in order to understand the adsorption of p-nitro-phenol (PNP) by using activated carbon as adsorbent in shallow bed technique method. Adsorption is still one of the preferred methods to remove phenolic compound in wastewater to this end. Palm Kernel Shell(PKS)Activated Carbonwill be used as the adsorbent in the experiment. Their adsorptive properties are due to their high surface area, a microporous structure and high degree ofsurface reactivity. Granular type ofactivated carbon is usually used in fixed bed adsorption process because of ease of operation and nocarbon loss. PNP is considered very hazardous. It induces methemoglobin formation. Inhalation or ingestion ofPNP may cause headache, drowsiness, nausea and cyanosis. Contact with the eyes may cause irritation. Respiratory effects, an increase in methemoglobin, effects on the liver and corneal opacity were reported in studies of acute exposure to PNP by U.S. EPA 1994. Thus, the choice to study the removal of PNP using PKS activated carbon adsorption is essential. Safety precautions before conducting the experiment are also taken into consideration. In a shallow bed column, the bedlength is very thin and is operated at adequate highflow rate. The advantage of shallow bed system is that the adsorption rate can be obtained directly, without having to depend on material balance because the mass transfer resistance at the fluidto- solid film surrounding adsorbent particles in this shallow bed column can be negligible. The PNP concentration will vary only slightly across the bed length. The amount of PNP adsorbed each time can be obtained by sampling the effluent at short interval. Spectroscopic method will be used for the result analysis.
