Phenol Removal From Synthetic Wastewater Using Batch Adsorption Scheme

Abstract

Phenol is one of the most dangerous pollutant of petroleum industry. Thus its removal is very essential. One of the most popular method used to remove phenol is through adsorption by activated carbon. In the present work, batch adsorption experiments are carried out under various operating parameters: pollutant concentration (CO) (10, 30, and 50mg/L), and activated carbon dose (CD) (250-1500mg/1.25L with an increment of 250). All experiments are performed at laboratory temperature (19ºC) and pH of 7 ± 0.1 while a full factorial mode is applied. Many adsorption models are used to fit experimental data and find out adsorption capacity (ADC) which is a widely used term.The results show that phenol can be completely removed and the adsorption capacity depends on the pollutant concentration (CO) and adsorbent dose (CD). The actual adsorption capacity (AADC) is calculated and found to be highly different from adsorption capacity.

Development of new effective activated carbon supported alkaline adsorbent used for removal phenolic compounds

“…Activated carbon (AC) can be defined as a carbonaceous material which having a porous texture and well-developed surface area. As a result, AC has been commonly utilized in separation processes or catalysis and as adsorbent [13][14][15][16]. MA et al [17] studied the elimination of phenolic compounds by utilizing powder activated carbon as adsorbent in batch reactor and it was found that more than 80% of phenolic compounds was removed at 10 min.…”

“…MA et al [17] studied the elimination of phenolic compounds by utilizing powder activated carbon as adsorbent in batch reactor and it was found that more than 80% of phenolic compounds was removed at 10 min. In some studies, using AC modified (prepared from agricultural wastes such as palm fronds, date stones and rice husk treatment via chemical and physical activation procedure and maximum capacity of removal (84.83%-94.65%) [13]. The study of the adsorption of phenol from an aqueous solution using tamarind seed powder (TSP) with adsorption process AD was investigated [25].…”
