This method is based on colorimetric analysis.The formaldehyde content is taken to be the quantity of free-formaldehyde and formaldehyde extractedthrough hydrolysis contained in a water extract from the leather under standard conditions.This process is not absolutely selective for formaldehyde. Other compounds such as extracted dyes could interfere at 412 nm.
