| 摘 要： | 采用IL公司微量小舟直接进样及电热原子化技术,将油样用二甲苯-碘混合溶剂稀释后直接进入微量小舟原子化,成功地实现了用无机标样法直接测定原油及渣油中微量镍的含量。该方法简单,取样量少,重现性好,样品测定的检出限达5ppb.

| Abstract: | This paper presents a method for direct determining micro nickel in crude oil and residual oil.The oil sample was diluted with a solvent of iodine and toluene,and injected into a microboat made by IL Company to be atomized by the use of electric heating'.Then micro nickel in crude oil and residual oil can be determined directly with the inorganic salt as standard.The method is convenient,sensitive and reproducible with a detection limit of 5 ppb. |
