description A sample pretreatment method for metal content analyzing, which contains heating the oil sample in inert gas to 450-700 degree centigrade to evaporate the volatile matter and remain metal element in residue, oxidizing the residue to convert metal element into metal oxide, added with inorganic acid to dissolve oxide and prepare into aqueous solution of sample. Said invention can be used in oil sample pretreatment of emission spectrum, atom absorption spectrum and color matching etc test.
