Synthesis of a Novel Hydrogel for Adsorptive Removal of Crystal Violet and Naproxen Pollutants from Wastewater

In this study, a novel synthesized pearlite/ferrite/guar gum (PFG) hydrogel was evaluated. Theoretical studies using molecular dynamics simulation through the Forcite module in Material Studio 2017 showed crystal violet (CV) and naproxen (NAP) dye drug adsorption relative to other dyes and drugs. One of the best ways to remove pollutants is adsorption. With the absorption method, harmful contaminants such as CV and NAP can be removed from the water and wastewater cycle. Morphology and functional groups of natural compounds and synthesized materials were determined using FT-IR, XRD, TGA, VSM, EDX, BET and FE-SEM analysis. The potential of the hydrogel to effectively remove CV and NAP from a saturated solution was studied experimentally based on the efficiency of adsorbent dose, pH and temperature. The composition follows the PSO kinetically and the Langmuir model in terms of the isotherm. The maximum absorption capacity of CV (244.40 mg/g) and NAP (180.15 mg/g) in hydrogel was investigated. According to the antibacterial activity test, the synthesized hydrogel had no antibacterial properties. Surface absorption is one of the common methods of removing colored and pharmaceutical pollutants from the wastewater industry. For this purpose, nanocomposites based on natural absorbents, magnetic materials and polymers are used. The advantage of using these three compounds for surface absorption, antibacterial activity and removing toxic pollutants (drug and dye) from the water and sewage industry has been investigated.image
