| Abstract |
Express detector-tube methods to determine acrolein and formaldehyde in mine air are based on their reaction with diazotised sulfanilic acid, as a result of which a yellow colour is formed. Silica gel KSK coated with sulfanilic acid and treated with nitric oxide is used as a solid carrier. The sensitivity of the indicating powder to acrolein is 0.1mg/m3 (range of measurement 0.2-2mg/m3) and to formaldehyde 0.05mg/m3 (range of measurement 0.1-1.5mg/m3). Determination time does not exceed 5min. Nitric oxide, carbon monoxide, formaldehyde and other aldehydes do not interfere with acrolein determination, but ammonia and hydrogen chloride do. The limit of admissible relative error is not more than 25%. |
