Abstract Determination of the concentration of formaldehyde in embalming fluid for specimens by back titration was proposed and the recovery rate and interference test were completed with sodium thiosulfate as the standard solution. The results showed that the method was simple, rapid, practical and had higher credibility, the average recovery rate exceeded 98%, three times coexisting substance did not have any interference.
