Abstract
A method for continuous air monitoring of sulphuric acid at workplaces is described. The monitor is equipped with a sampling inlet specially designed for sulphuric acid aerosol. In this inlet the aspirated air is wetted with pure water and on-line transferred to a gas/liquid separator. After separation of the phases, the aqueous phase is directed through a conductivity detector. The monitor has been used in a yarn production plant in which light concentrations of sulphuric acid have been used. Application of this monitor gave insight into the efficiency of the ventilation systems under high spinning speed conditions.
