CARDONA GALLO, SANTIAGO ALONSO. OBTAINING OF THE COEFFICIENT OF ORGANIC CARBON FOR DIESEL THROUGH ISOTERMAS OF ADSORTION. Dyna rev.fac.nac.minas [online]. 2007, vol.74, n.153, pp. 159-165. ISSN 0012-7353.
In this work the experimental values of the coefficient are presented of sorption organic carbon, Koc, for fuel diesel of Mexican production which is a mixture of composed and whose value is not reported in the literature specialized, only for rank interval of sediments and soils. The coefficient of distribution, Kd, of the majority of the organic compounds is increased with the fraction of organic carbon, foc, implying that another option to obtain Kd is through the coefficient of sorption Koc and foc by means of the relation Kd = foc Koc. The values of Kd were determined through isotherms adsorption, for which five types of different floors were tested, five concentrations of diesel in intermittent reactors and itself model the process with the equation of Freundlich considering n = 1 for the lineal adjustments. Values were obtained of Koc in a rank from 44.82 to 55.62 mL/g. The analysis was carried out of variance and applied the test of multiple intervals of Duncan to determine the difference among the averages of the Koc obtained. Graphic the influence of the foc in the adsorption of the diesel was presented.
