| 中文摘要: |
| 论证了空心阴极氘灯背景扣除能力.用火焰原子吸收法测定炖铝中锌时会遇到背景吸收问题,分别使用了空心阴极锌灯和空心阴极氘灯对含锌量为0.0032%纯铝试样进行两次测定,当测试溶液的基本浓度为0.5%(m/V)时,不扣背景测定也令偏高至0.0044%,扣除背景后规定值为0.0034%. |
| 英文摘要: |
| In this paper,a deuterium hollow cathode lamp was used to eliminate the background in determining Zinc in pure aluminium in air/acetylcne FAAS. A standard sample of 0. 0032% of Zn inpure alurninium was detected two times by a Zinc and a deuteriuxn hollow cathode lampe. In a matrixconcentration of 0. 5%(m/v), 0. 0044% Zn was detected with no background correction and 0.0033% Zn was did with background correction . |
