ABSTRACT:
Method for the determination of lecithin concentration in crude oil. A sample of crude oil is admixed with a polar organic sample which does not dissolve lecithin, thus obtaining a suspension. The concentration of lecithin in the suspension is determined by the turbidimetric analysis, by measuring the transmitted light passed through the suspension. According to a preferred embodiment, a tungsten lamp provides the light to be transmitted through the suspension, the light passed being converted to Lux units by Luxmeter and expressed into concentration values of lecithin.
