Colorimetric determination of sulfur dioxide in air using a droplet collector of malachite green solution
(Academic Press Inc., 1999-06-01)
The measurement of sulfur dioxide in air at the parts-per-billion level is described. The experimental arrangement consists of two optical fibers placed on opposite sides of a liquid droplet of malachite green solution. ...
