今年三月,中国科学院环境分析化学考察组赴加拿大的渥太华、多仑多和海力弗斯等城市和地区作了为时一个月的考察。这次考察主要着重于环境分析化学的研究工作,以研究单位和大学为主,总共访问了十七个单位,并与加拿大的许多科学家见了面,进行了友好而有益的讨论。在无机分析方面,加拿大的原子吸收光谱研究具有一定的特色.握太华卡诺登大学化学系Chakraba吐i在解决石墨炉基体效应的工作中,设计了石扭片平台和电容放电加热,在提高灵敏度和排除干扰方面取得了良好的效果.在海力弗斯台尔哈寺大学痕量分析中心,空心阴极灯上加磁场的齐门(Zeetnan)原子吸收光谱仪已基本完成,可校正10%抓化钠在铅(2朋3入)的背景吸收,现正在开展磁光旋转(MOR)的工作.国家科学委员会(NRC)的化学所的McLaren结合预富集,研究海水中
In March this year, the Chinese Academy of Sciences Environmental Analytical Chemistry Study Group went to Canada for Ottawa, Toronto and Hailuofusi and other cities and regions made a month-long study. The study mainly focused on the research work of environmental analytical chemistry, which was mainly conducted by research institutes and universities. It visited a total of 17 units and met many Canadian scientists and conducted friendly and helpful discussions. In inorganic analysis, the Canadian Atomic Absorption Spectroscopy study has some characteristics .Can Taihua Department of Chemistry, University ofCanorden Chakraba spit i in the work to solve the graphite furnace substrate effect, the design of the stone twist plate platform and capacitor discharge heating, in Improve the sensitivity and eliminate interference has achieved good results in the Hiliforsal Ha Temple University Trace Analysis Center, Hollow cathode lamp with Zener Zemen (Zemen atomic absorption spectrometer has been basically completed, can be corrected 10% Grazed sodium is absorbed in the background of lead (2P3) and is now working on magneto-optical rotation (MOR).
