Özet
In this study, a three-dimensional (3D) porous polydimethylsiloxane (PDMS) was prepared using a cheap material with a highly simple and different method. PDMS was firstly applied for the removal of carbol fuchsin (CF) cationic organic dye pollution in this study. Besides, the adsorption capacity of 3D PDMS for removal of the CF was found quite high compared to other materials in already published results. The synthesized PDMS was characterized using several spectroscopic and imaging techniques such as FTIR, Raman, SEM, stereomicroscope, EDX, UV/Vis, and TGA. The optimal conditions were found as 10 mg L−1 initial concentration, 20 mg of adsorbent dose, 2 h contact time, pH 10, and 25°C temperature. The removal % of CF and the maximum adsorption capacity were calculated at approximately 89% and 88.8 mg g−1, respectively. Furthermore, the equilibrium studies showed that the Langmuir isotherm model fitted well with the removal of CF. Moreover, according to the kinetic results, the second-order kinetic model was found suitable (qe,cal 89.3 mg g−1 and qe,exp 88.8 mg g−1 close to each other) for the adsorption of CF. Also, the thermodynamic studies indicated that adsorption occurs spontaneously, and the adsorption process was physical adsorption. Besides, the reusability of the adsorbent was studied. Practitioner points: Water treatment technology should be low cost, economically viable and in the meantime, eco-friendly. The 3D porous PDMS was prepared by using cheap material with a highly simple method and eco-friendly This unique material was firstly applied for the removal of organic dye in water in this study.
