A low-cost CK gas analytical device using UV-Vis spectrometry for the determination of CK gas has been developed. In order to reduce the device price and miniaturize the device size, the light source and detector of analytical device consist of LED light source and CCD, respectively. A application evaluation of the analytical device using CK gas was studied. Based on the mechanism of iodine redox reaction and konig reaction, two CK gas absorbent solutions was prepared and optimized. Under the optimized conditions such absorbent solutions, the calibration curve was linear over the range of 10 to 100 ppm for iodine absorbent solution and 5 to 50 ppm for barbituric acid absorbent solution, respectively. The correction coefficient of each calibration curve was calculated to be 0.9936 for iodine absorbent solution and 0.9950 for barbituric acid absorbent solution.
