Claim 5:
6. The method according to claim 1, wherein a method for detecting H2S with the help of the photographing function of the intelligent device and the color picking software comprises the following steps: data measuring: the RGB values are provided directly from the captured image by the color picking software; standard curve plotting: the calculated difference of the R values is taken as the ordinate, and the logarithm of the concentration is taken as the abscissa to obtain a standard curve; and data reading: the limit of detection is obtained from the obtained standard curve according to LOD=36 black/k, where LOD refers to the limit of detection, 6 black is the standard deviation of a blank solution, and k is the slope of the standard curve.
