| Summary: | This study was
conducted to examine the ion absorption behavior of zwitterionic sulfobetaine
type N,N-dimethyl(acrylamidopropyl) ammonium propane sulfonate (DMAAPS) gels. In addition,
it also examines the effect of salt solution concentration and ionic strength on the poly(DMAAPS) transition behavior in
different salt solutions. The adsorption behavior of the
gel in nitrate, chloride and sulfate
solutions was found to be a strong function of the valence. The number of ions adsorbed onto the DMAAPS
gel increases in line with the increase of cations valences, with the order of
adsorption being Zn2+ > Ni2+ > Na+, K+. The level of ion adsorption onto the DMAAPS gel in various salt solutions with common
cations of Na+,
K+ and Zn2+ shows a
tendency in the order of NO3? > Cl? > SO42?. Comparing the effect of
the anion and cation of the same charge on the
number of ions adsorbed, the anion species effect is greater than that of the
cation species at all concentrations. At first, the transition temperature of the poly(DMAAPS) within the salt solution increases.
However, it then decreases when the ions adsorbed onto the DMAAPS gel increase and reach a maximum level.
On the other hand, the level depends on the species and ion concentration.
Therefore, it can be concluded that the maximum level of ions adsorbed can be
simply ascertained by determining the transition temperature. |
