Description

In combination with the standard curves of normal and low concentrations (Figure 4b and Figure 4c), it can be seen that the absorbance was linearly related to formaldehyde content in the range of 0-5 g mL -1 (Figure 4d), and its regression equation was A = 0.3944C + 0.124, which is basically consistent with the regression equation of the standard curve of high concentration, with a correlation coefficient R=0.9997
