Adsorption of Crystal Violate (Cv) Dye in Aqueous Solutions by using Zno/P (Aa-Ca) Composite as Adsorbate Surface Characterization, Thermodynamics And Equilibrium Evaluation

Abstract

Toxic dyes in water have put human health at risk all around the world. We used biodegradable polymers such as ZnO/Poly (Acrylic acid-Crotonic acid) hydrogel (ZnO/P(AA-CA)) to make an excellent absorbent hydrogel for the removal of pollutant crystal violet dye (CV) from aqueous solutions. Diagnostic methods such as FT-IR, FE-SEM and XRD were used to examine the produced materials. Tests on CV dye adsorption via hydrogel and the influence of different parameters such as temperature, CV dye concentration and isotherm modules were conducted. The correlation coefficient (R2) indicated that the adsorption process followed the Langmuir model, which was confirmed by the data. It is clear from these results that hydrogels are a cost-effective and efficient biomaterial for eliminating CV dye from water.
