Polyvinyl Alcohol Film

The glutaraldehyde (GA)-crosslinked carboxymethyl cellulose (CMC)-polyvinyl alcohol (PVA) film had been synthesized and used as a methylene blue adsorbent. The films were prepared using a solution casting technique and characterized using FTIR spectrophotometer, SEM. Adsorption studies include pH, contact time, methylene blue initial concentration. Furthermore, the desorption study of films was carried out using NaCl, HCl and distilled water. The results of FTIR characterization showed similarities between the spectra of CMC-PVA-GA films with their component materials. The SEM image of CMC-PVA-GA films showed a non-porous surface. In the adsorption study, GA-crosslinked CMC-PVA films (1:2 w/w) exhibited the largest adsorption capacity of methylene blue at optimum conditions for adsorption at pH 7, contact time 200 min, methylene blue concentration of 200 mg L–1 which was 194 mg g–1. Methylene blue adsorption kinetic followed the pseudo second-order kinetic model and the Langmuir adsorption isotherm model. The desorption studies show that adsorption takes place through an ion exchange mechanism.
