1981年国际理论化学和应用化学联合会(IUPAC)把电热原子吸收分光光度法定为测定血和尿中镍的参考方法,Jin Long-Zhu等对此法进行了改进,采用石墨炉分析。此两法由于取样量少,且需特制的仪器,操作要倍加细心。Sunderman FW 等把尿稀释直接石墨炉测定,但须有塞曼扣除背景。李修平等以示波极谱法测定尿镍。1989年7月我国通过了
In 1981, IUPAC used the method of electrothermal atomic absorption spectrophotometry as the reference method for the determination of nickel in blood and urine. Jin Long-Zhu et al improved this method and analyzed by graphite furnace. Due to the two methods of sampling less, and the need for special equipment, the operation should be more careful. Sunderman FW and other diluted graphite furnace direct determination, but must have Zeman deduction background. Li Xiu-ping and other polarographic determination of urine nickel.
