Method for determination of percentage of mixture of biodiesel in diesel oil

摘要

Method for determination of percentage of mixture of biodiesel in diesel oil, consists of a simple procedure for determining the percentage of mixture of biodiesel in diesel oil by using the measure of absorption of radiation in the infrared spectrum medium, more specifically in the range Between 1870 - 1540 cmu00ac - 1u00ac the absorption peak corresponding to the elongation of the carbon oxygen double bond.Also known as the peak of the carbonyl (C = O), existing in this region is present only in the biodiesel, and therefore can be used in the determination of the presence of the component in a mixture of Biodiesel - diesel oil. There was the existence of a nonlinear dependence between the height of the absorption peak and the percentage of the mixture in the range of 0 to 100%.This dependence obeys a power law specific can be analysis by electronic processing later. He was also in the band reduced from 0 to 10%. The relationship can be approximated by a straight line with good reliability.
