Adsorption Kinetics and Thermodynamics of a Malachite Green from Aqueous Solutions by Novel Nanocomposite Hydrogel Ntadbrp-Poly (Aac-Co-Ca)

Abstract

The adsorption of Malachite green from solution onto the surface of NTADBrP-P(AAC-co-CA) is the subject of this investigation. Although not very effectively, the nanocomposite hydrogels may remove this dye from aqueous solution. At various ionic strength and temperature settings, quantifiable adsorption data have been produced using UV-Visible spectrophotometric method. According to Giles classification, the adsorption isotherms are of the S4-curve type, and the experimental data were best suited by the Langmuir and Freundlich isotherm models. The outcomes demonstrate a higher dye adsorption absorption on nanocomposite hydrogels. Temperature effects on the adsorption were studied (15, 20, 25, 30 ). Malachite green's degree of adsorption on NTADBrP-P(AAC-co-CA) was shown to diminish with rising temperature (exothermic process). The fundamentals of thermodynamics have.
