INFLUENCES OF CATIONS, ANIONS AND SURFACTANTS ON MOLECULAR COIL DIMENSIONS OF PARTIALLY HYDROLYZED POLYACRYLAIMDE
|
Abstract:
The influences of cations,anions,anionic surfactant and non-ionic surfactant on the molecular coil dimension of hydrolyzed polyacrylamide(HPAM) were studied by using dynamic light scattering(DLS),and ther mechanism was analyzed by applying the Stern-Graham double electrode layer model theory,paternoster model theory and dynamic model.The results show that the influence of anions on the HPAM molecular dimension(D_h) is little,but comparing against anions,the influence from cations is much greater,and the dec...
