“…The strong peaks at ~ 1720 cm −1 reveal the presence of -COOH of Methacrylic acid. Moreover, the peaks ~ 1635 cm −1 , ~ 1452 cm −1 , ~ 1300 cm −1 , and ~ 1200 cm −1 correspond to the presence of C = C, -CH 2 stretching, -CH 3 group and C-O stretching, respectively [37]. Furthermore, the band at ~ 1157 cm −1 associated to the sulfonate group of CR can be clearly seen suggesting the presence of CR in MIPs.…”

Congo red (CR) is an anionic azo dye widely used in many industries including pharmaceutical, textile, food and paint industries. The disposal of huge amount of CR into the various streams of water has posed a great threat to both human and aquatic life. Therefore, it has become an important aspect of industries to remove CR from different water sources. Molecular imprinting technology is a very slective method to remove various target pollutant from environment. In this study a precipitation polymerization was employed for the effective and selective removal of CR from contaminated aqueous media. A series of congo red molecularly imprinted polymers (CR-MIPs) of uniform size and shape was developed by changing the mole ratio of the components. The optimum ratio (0.1:4: 20, template, functional monomer and cross-linking monomer respectively) for CR1-MIP from synthesized polymers was able to rebind about 99.63% of CR at the optimum conditions of adsorption parameters (contact time 210 min, polymer dosage 0.5 g, concentration 20 ppm and pH 7). The synthesized polymers were characterized by various techniques such as Fourier Infra-red spectroscopy (FTIR), scanning electron microscopy (SEM), Thermogravimetric analysis (TGA), energydispersive X-ray spectroscopy (EDX), and Brumauer-Emmett-Teller (BET). The polymer particles have successfully removed CR from different aqueous media with an efficiency of about ~ 90%.

“…To obtain the cross-linked and grafted onto chitosan carbochain polymers with the side COOH groups, the in situ radical graft polymerization of metacrylic acid onto succinoyl chitosan was carried out in aqueous medium in the presence both N,N′-methylenediacrylamide as the crosslinking agent and (NH 4 ) 2 S 2 O 8 as the water soluble photoinitiator [145]. Crosslinked succinoylchitosan-graft-poly(metacrylates) were synthesized.…”

A series of poly (methacrylic acid-Co-maleic acid), P(MAA-MA), hydrogels have been prepared by free radical polymerization in aqueous medium using different amount of maleic acid (MA) (0-5 wt.%), initiated by potassium persulfate (KPS) in the presence of N,N'-methylenebisacrylamide (MBA) as a crosslinking agent. Fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA) and scanning electron microscope (SEM) techniques were used to characterize the prepared hydrogels. Their swelling behaviours were investigated according to the maleic acid content and pH of solution. Kinetic swelling of hydrogels was studied too. The results showed that the swelling ratios increase with increasing the maleic acid content. Kinetic studies showed good fitting to pseudo-second order equation. The prepared hydrogels obeyed non-Fickian water diffusion.
