We will start a RIL operation and we will use kerosene to passivate carbonaceous matter. I would like to know if there is any method of kerosene analysis.

You will use kerosene and an ion-exchange resins to adsorb the gold. There are not many operations using a resin process (RIP, RIL or RIS). The advantages of the resin over activated carbon are the better gold loadings and the resistance to fouling by the addition of kerosene. The kerosene addition ranges from 5 to 10 L/t of ore. It is small dosage. Resin elution should not be a problem. If you want to detect small contents of kerosene you could use chromatography and high-resolution mass spectrometry techniques.
