Abstract

Indirect determination of molecular chlorine by Fourier Transform Infrared Spectroscopy (FTIR) was reported. The concentration of chlorine gas was examined with a wide-range vacuum system following introduction of a known quantity of chlorine gas and normal air at atmospheric pressure into the evacuated gas cell. The UV lamp was switched on after recording the first single beam spectrum preceded through photolysis. The result was analyzed by plotting graph for quantitative determination of hyphochlorous acid (HOCL) preceded by changes in HOCL subtraction factors was determined during the photolysis. It was concluded that checking the concentration of HOCL, original chlorine concentration in the gas cell was achieved and unknown chlorine can be traced out from the gradient of concentration change of the HOCL released during photolysis in the range of 3-18ppm.
