在文中所述条件下,镍的原子捕集灵敏度较常规法高320倍,即在离子交换法浓缩仅40倍的情况下,可使镍的测定灵敏度提高12800倍,从而成功实现了ppt级超痕量镍的测定。
Under the conditions described in this article, the atomic capture sensitivity of nickel 320 times higher than the conventional method, that is, in the ion exchange method only 40 times the concentration, the determination of nickel can increase the sensitivity 12800 times, which successfully achieved ppt super Determination of trace nickel.
