Product Introduction
AEPD is a biochemical reagent with a molecular weight of 119.16, soluble in water. AEPD can be used as an additive in aqueous suspensions to improve the conductivity of suspensions, can be used as an alkalizing agent in hair forming compositions, can also be used as a component of polyurethane foam, and can also be used in inks.
Application of AEPD
Formaldehyde is a carcinogen recognized by the World Health Organization and ranks second on China's priority list of toxic chemicals. It can greatly harm human health. Depending on the concentration of formaldehyde in the exposed environment, exposure time, and individual physical differences, formaldehyde can cause symptoms as mild as dizziness, abdominal pain, and respiratory damage, as severe as liver and kidney function damage, and even chromosomal abnormalities.
The traditional purification methods for indoor formaldehyde mainly include adsorption, catalytic oxidation, plasma technology, ozone oxidation, and biological purification. The use of adsorption method for indoor formaldehyde removal is more feasible compared to other purification methods. However, due to the problems of short action time, low efficiency in removing formaldehyde, and incomplete degradation of adsorbents used in existing adsorption methods, it is necessary to explore a new type of adsorbent for formaldehyde purification. Therefore, CN116037079A patent has developed an adsorbent and its preparation method for purifying formaldehyde.
The adsorbent is composed of the following raw materials (by weight): 23 parts chitosan modified bentonite, 14 parts modified manganese based particles, 8 parts activated 10X zeolite molecular sieve, 2.0 parts 2-amino-2-ethyl-1,3-propanediol, 4.2 parts vinyl imine, 1.6 parts boron nitride, and 1.0 part nano copper hydroxide.
The present invention is an adsorbent for purifying formaldehyde, which adsorbs and degrades formaldehyde through physical adsorption and chemical degradation of chitosan. In order to ensure the removal rate and efficiency of formaldehyde, a complex of 2-amino-2-ethyl-1,3-propanediol and vinyl imine is added to eliminate formaldehyde through chemical reactions. However, if chitosan modified bentonite is not used The physical adsorption provided by modified manganese based particles and activated 10X zeolite molecular sieve will significantly reduce the chemical degradation of the complex of 2-amino-2-ethyl-1,3-propanediol and vinyl imine. In addition, in order to make the prepared adsorbent for purifying formaldehyde have disinfection and sterilization effects, additional boron nitride and nano copper hydroxide were added.
