Title : Ftir band interpretation of hydrocarbon oils and oil spill identification 


Due to the rapid growth of various technological and industrial revolution, the earth is facing several problems. Her resources like water and air are critically polluted. Advanced industrialization causes major pollution. Each year an estimated five to ten million tons of oil are jettisoned into the oceans. Eighty percent of this spilled oil remains in the environment, directly affecting the life of the human beings, aquatics and also marine organisms.  Whenever oil is produced, stored or transported there exists a potential source of oil pollution either directly by surface drains or indirectly by seepage into the ground.  The environmental scientists have estimated that the rivers contain many organic substances causing pollution as a result of industrial activity. For more than a four decades Infrared Spectroscopy has been used as an important tool for determining the chemical composition of crude oils and their refined products.  More recently infrared spectroscopic methods have been developed to identify the source of oil spill by matching finger prints of known and unknown samples.This application of Infrared spectroscopy has been used mainly by spectroscopists to trace the origin of oil slicks. The applicability of computer analysis of infrared spectral data on several unknown oil samples has been carried out in past.

Crude oil is called as rock oil is gifted by the earth. But in return the same factor is adversely affecting her own rich and useful environment.  In this connection, the oil spill in the sea and oceans has caused a great environmental impact on the entire marine eco-system. In the present study a modern technique, FTIR spectroscopy is used for oil spill identification. Identification of the oil spill is carried out by matching the finger print bands of the known and unknown hydrocarbon samples
