Zhang Qinglian's contribution to chemical scientific research: Scientific research is the foundation of human civilization accumulation, which is Zhang Qinglian's creed and also constitutes his life values. Since 1935, he has been focusing on water and stable isotopes, involving isotopes of more than ten elements such as hydrogen, oxygen, carbon, nitrogen, lithium, boron, sulfur, indium, antimony, cerium, europium and iridium.
In the past 50 years, the physical and chemical properties of isotopic compounds, the dynamic effect of isotopes, the principle and method of isotope separation, the development of isotope standard samples, the determination of natural abundance and atomic weight of isotopes, etc. have been systematically and deeply studied, and more than 0/00 related papers have been published.
Professor Zhang Qinglian has made outstanding contributions in determining the relative atomic mass. By 2005, the new values of relative atomic mass of ten elements, such as indium, iridium, antimony, europium, cerium, erbium, germanium, zinc and dysprosium, which he presided over, were adopted as new international standards by the International Atomic Weight Committee.
Zhang Qinglian (June 65438+July 31.0908—June 65438+February 14, 2006), born in Changshu, Jiangsu Province, is an inorganic chemist, educator, academician of China Academy of Sciences and professor of School of Chemistry and Molecular Engineering of Peking University.
After graduating from the Chemistry Department of Guanghua University on 1930, Zhang Qinglian taught in Changshu Xiaoyou Middle School for one year. 1934 After graduating from Tsinghua University, he entered the Department of Physical Chemistry of Berlin University. From 65438 to 0936, he received his Ph.D. from Berlin University and worked in the Institute of Scientific Physical Chemistry of the Royal Swedish Academy for one year. After returning to China from 65438 to 0937, he served as an associate researcher at the Institute of Chemistry of Academia Sinica.
Guanghua University professors from 1938 to1939; 1939 to 1946 Professor of National Southwest Associated University; Professor Tsinghua University from 1946 to1952; 1952 to Peking University; 1978 to 1983, concurrently head of the Department of Chemistry of Peking University; 1954 to 1956, employed as academic secretary of China Academy of Sciences.
1955 was elected as an academician of China Academy of Sciences; From 1980 to 1984, he was elected as the first president of China Mass Spectrometry Society; 198 1 to 1992, deputy director of the Institute of Chemistry, Chinese Academy of Sciences; 65438+He died in Beijing in February 2006 at the age of 99. Zhang Qinglian has been engaged in the teaching and scientific research of inorganic chemistry for a long time, as well as the research on the determination of atomic weight by isotope mass spectrometry.
