Frederick Cottrell

Frederick Gardner Cottrell (1877 - 1948) is an especially known electrochimist for his equation (equation of Cottrell) and to have invented the electrostatic Précipitateur.

Youth and studies

Child, Cottrell was interested in photography, electricity, telegraphy, and the publication of newspapers. Extremely curious, he was an extraordinary reader. After the college, it entered to the the University of California at the 16 years age, and was graduate in 3 years. It has pousuivi its studies in Germany, initially with Berlin then with Leipzig where it obtained a doctorate in 1902.

Career

Whereas he taught with the the University of California, Cottrell was made employ by Dupont in 1906 in order to eliminate a problem of pollution during the manufactoring process of the sulphuric Acid . Indeed, the production of the acid synthesized arsenic, which polluted catalyst. Cottrell discovered that the centrifugation of the fumes acid polluted made it possible to eliminate arsenic. The problem was then to precipitate the purified vapors, that Cottrell solved while running a current in the vapor, thus the ions accumulated with each electrode could be collected (proceeded Cottrell). It used electrostatics thereafter in order to filter industrial smoke. In 1912, it creates the Research Corporation, which still today finance of many scientific projects. Projects financed in the past: the Cyclotron of Lawrence, the experiments of Goddard in Fuséologie, and of the methods of production of vitamins has and B1.
