b. Some professional companies usually use sensors to detect formaldehyde. Current sensors include: electrochemical sensors, biochemical sensors, and optical sensors. In comparison, the structure of the electrochemical sensor will be relatively simple, and the cost will be lower, and the performance will be more stable, which can basically meet the detection requirements.

c, detection of formaldehyde can also use the magenta-sulfurous acid, phenol reagent method, chromotropic acid method, catalytic spectrophotometry, acetylacetone method, phloroglucinol method to detect whether the standard.
