Adsorption of Oil Spill from Sea Water using Coconut Shell Powder
Oil Spill has resulted in severe impact on marine ecosystem as oil spill can have toxicological effects which when consumed, can affect the human respiratory system. Also, the oil and gas industry has had to deal with a massive amount of waste water as a by-product of the exploration of oil and gas. Methods which are used to purify water from petroleum and oil products are: mechanical, physicochemical, chemical and biochemical. Adsorption is a very effective and easily interpreted physicochemical method. In our study, we have highlighted the benefits and procedure of removing oil from seawater using coconut shell powder which is a natural and easily available adsorbent. UV Spectroscopy has been performed to support the feasibility of coconut shell powder as our agent of adsorption. We studied the effect of bed height with respect to removal efficiency analytically. The removal efficiency increases with increase in bed height. Correlation between the Freundlich adsorption isotherm model and adsorption equilibrium data was done and it was found that adsorption equilibrium data was better than the Langmuir model eventually in our experiment.
