Abstract
This work is devoted to development scheme of continuous on-line control of the content of phenol in working area air using chromatomembrane liquid absorption and fluorimetric detection. Optimal rates of gas and liquid phases were determined and good convergence between continuous chromatomembrane liquid absorption variant of analysis and classic absorption into bubbler with chromatographic detection were shown. Completeness of absorption of phenol in a continuous chromatomembrane liquid absorption were determined not less than 98 %. Benefits of the developed scheme are simple automation, minimal time of operator parcipitation during analysis, no reagents using. It is possible to determine concentration of phenol in working area air in the range of 20 % of the maximum permissible concentration of up to 5 MPC with a frequency of 3-4 tests per hour. Keywords: chromatomembrane liquid absorption, automation of analysis, monitoring of the environment (Russian) DOI: http://dx.doi.org/10.15826/analitika.2013.17.4.016 A. L. Moskvin, A. N.
