| titleOfInvention | A kind of detection method of quaternary ammonium group density on the outer surface of quaternary ammonium resin |
| abstract | The invention discloses a method for detecting the density of quaternary ammonium groups on the outer surface of a quaternary ammonium resin, and belongs to the technical field of chemical analysis. It includes mixing tetraphenyl borate with a molar amount of M 1 and a quaternary ammonium resin under alkaline conditions, and then performing a standing reaction, and after the reaction is completed, adding hexadecyl trimethyl ammonium bromide and the remaining tetra Phenyl borate reacts; before adding cetyl trimethyl ammonium bromide to react, add dadan yellow, stop adding cetyl trimethyl ammonium bromide when the solution after adding dadan yellow changes color, add the The molar weight of cetyltrimethylammonium bromide is M 2 ; the dry weight of the quaternary ammonium resin is M total , and its surface quaternary ammonium group density is (M 1 -M 2 )/M total . The invention can effectively quantitatively measure the density of the quaternary ammonium groups on the surface of the quaternary ammonium resin, and has the advantages of simple operation, accurate quantification and high repeatability. |
