“…The monomer of N,N-dimethyl(acrylamidopropyl) ammonium propane sulfonate (DMAAPS) was synthesized through ring opening reaction of N,Ndimethylaminopropylacrylamide (DMAPAA) and 1,3propane sultone (PS) proposed by Lee and Tsai [17] using the same method as in our previous study [18][19][20]. The following ring opening reaction occurs ( Fig.…”

The properties of N-isopropylacrylamide copolymerized with N,N-dimethyl (acrylamidopropyl)ammonium propane sulfonate [poly(NIPAM-co-DMAAPS)] prepared with various monomer ratios such as transition temperature, molecular structure, viscosity were systematically investigated in water and Zn(NO3)2 solution. Poly(NIPAMco-DMAAPS) in water and Zn(NO3)2 solution exhibited a phase transition with a lower critical solution temperature (LCST). The higher ratio of NIPAM monomer in poly(NIPAM-co-DMAAPS), the lower the LCST of the polymer. Furthermore, the transition temperature of poly(NIPAM-co-DMAAPS) with a lower NIPAM concentration were not confirmed both in water nor Zn(NO3)2 solution. The more increase the NIPAM concentration used in the preparation, the more increase the polymer viscosity. Moreover, the more increase the adsorption amount of ions onto the gel, the more increase the polymer transmittance as well.

“…DMAAPS was synthesized by the same manner as that used in our previous studies [15][16][17], which was proposed by Lee and Tsai [18], by the ring-opening reaction of N,N-dimethylaminopropylacrylamide (DMAPAA, KJ Chemicals Co., Ltd., Japan) and 1,3-propanesultone (PS, Tokyo Chemical Industry Co., Ltd., Japan). A mixture of PS (75 g) or BS (79 g) and acetonitrile (75 g) was added dropwise with continuous stirring at 30°C for 90 min into a mixture of DMAPAA (100 g) and acetonitrile (200 g).…”

“…The phenomenon above can be explained as follows. At higher temperature, thermal motion weakens the interaction between the charged groups of DMAAPS (N + and SO3 − ) and cation Na + and anion (NO3 − ) from NaNO3 solution [15][16][17]20], as a result, the adsorption ability of copolymer decreased as temperature increased. The adsorption are less influenced by temperature change because gels prepared using high cross-linker concentration, the interaction is dominated by intra-group ionic pairs that is quite strong to be broken by thermal motion.…”

Adsorbent gel with the ability to absorb and to desorb Na + and NO3 − ions simultaneously with temperature swing was synthesized by free radical copolymerization reaction of N-isopropylacrylamide (NIPAM) and N,Ndimethyl(acrylamidopropyl) ABSTRAK Gel adsorben yang memiliki kemampuan mengadsorpsi dan mendesorpsi ion secara simultan dengan perubahan suhu (temperature swing) dihasilkan melalui reaksi kopolimerisasi radikal bebas antara Nisopropylacrylamide (NIPAM), dan N,N-dimethyl(acrylamidopropyl)ammonium propane sulfonate (DMAAPS

“…The increase in adsorption ability was affected by the presence of NIPAM which acts as the separator between DMAAPS molecules. NIPAM is a thermosensitive polymer well at low temperatures (Ningrum et al, 2017b). When NIPAM expanded, the distance between DMAAPS molecules increased and the intra-chain, inter-chain and intra-group bonds decreased.…”

The present research was performed aiming to develop gel with the characteristic of reversible thermosensitive in adsorbing heavy metal ions from its solution. There were three gels used in this study to adsorb heavy metal ion from salt solution provided Zn(NO3)2; copolymer gel consisting of zwitterionic betaine N,N-dimethyl(acrylamidopropyl)ammonium propane sulfonate (DMAAPS), N,N-dimethyl(acrylamidopropyl)ammonium butane sulfonate (DMAABS), and DMAAPS copolymerized with thermosensitive N-isopropylacrylamide (NIPAM) gels. The aforementioned gels were employed to examine its ability in adsorbing and swelling after being synthesized through free radical polymerization before being affected by methylene spacer number, copolymerization, and temperature given. This research found that as the temperature increases, the ability of the gel in adsorbing the ions decreases. In the case of DMAAPS and DMAABS gel, the swelling degree value increases when the temperature also increases. Meanwhile, sulfobetaine which has larger spacer has higher adsorption ability but not with its swelling degree. In spite of having more spacer than DMAAPS, DMAABS found to have the smallest swelling degree value. In addition, NIPAM-co-DMAAPS was found to have both the highest adsorption ability and swelling degree value. Even though copolymer has less amount of sulfobetaine than DMAAPS and DMAABS gels’, the copolymer gel was found to have higher ability of adsorption as many as ten times of other gels.
