Title Determination of molybdenum aerosol in workplace air
Original title Opredeljane na molibdenovi aerozoli văv văzducha na rabotnata sreda [in Bulgarian]

Abstract A rapid method of quantitative determination of molybdenum in workplace air was developed. The method is based on the reaction of hexavalent molybdenum cation with rhodanate anion in the presence of a reducing agent. The concentration of molybdenum is determined from the intensity of the colour of the resulting molybdenum pentarhodanate. A sensitivity of 0.1µg is obtained by this method. The studies carried out with this method during the process of welding with electrodes containing 2.5% molybdenum in their coating showed that the concentration of molybdenum aerosols in the air investigated was under the MAC.
