ABSTRACT:

This experimental study aimed to compare the adsorption of oleic acid (fatty acid) by two adsorbent; activated carbon and carbon nanotube by use of Uv-Vis spectrophotometer Jenway 6505 model. In this study, five different concentrations of oleic acid in the range of 282.47ppm to 847.41ppm were used. In all conducted experiments, the values of adsorbents, exposure time, temperature, and pH were assumed constant. Based on the results, under similar conditions the efficiency of adsorption of oleic acid by carbon nanotube was more than activated carbon. The results can be beneficial in pharmaceutical, oil and construction industries, biology and advanced water and wastewater treatment plant.
