Formaldehyde can cause significant harm to the human body. Long term intake can lead to headaches, dizziness, fatigue, sensory disorders, weakened immunity, and symptoms such as memory loss or neurasthenia. Additionally, formaldehyde is also one of the Class 1 carcinogens. Formaldehyde in water and soil can cause pollution, killing microorganisms and poisoning aquatic animals, seriously endangering the environment. China has clear formaldehyde content limits in drinking water, drainage and other standards.

Pre made formaldehyde reagent for water quality testingThe formaldehyde supporting reagent developed based on the national standard formaldehyde phenol reagent (MBTH) spectrophotometric method (GB/T 16057-1995) has the advantages of convenient testing operation, low cost, and reliable results, which can meet the needs of users for batch, rapid, and accurate water sample detection.

Technical principles

Pre made formaldehyde reagent for water quality testingBased on the national standard formaldehyde phenol reagent (MBTH) spectrophotometric method (GB/T 16057-1995): Under weakly acidic conditions and catalyzed by trivalent iron ions, formaldehyde reacts with phenol reagent to produce blue color. The color system has a certain concentration range, and the depth of blue color is proportional to the concentration of formaldehyde.
