2024-09-26T11:41:16+00:00

The grafted nanocopolymers were synthesized via an esterification process, where the first step was to generate a linear copolymer by reacting terephthalic acid with glycerol. Then, a certain amount of maleic anhydride was added to the resulting linear copolymer solution to obtain the grafted PTGM nanoparticles. The prepared nanopolymers were characterized using FT-IR spectroscopy, ¹H-NMR, and atomic force microscopy (AFM). The average particle height was 8.3 nm and was exposed to three different temperatures (298, 308, and 318 K). Four different concentrations (1, 3, 5, and 7 ppm) of the nanocopolymers were examined and it was evident that they play a vital role in the adsorption process. The experimental results showed that the average surface area of this nanopolymer for adsorption of dye (methyl orange) decreased with increasing temperature, indicating that the process is endothermic. It was also observed that the highly efficient nanocopolymers were able to successfully remove (methyl orange) from aqueous solutions.

2024-11-10T15:30:34+00:00

This study used Lie transformations to provide both numerical and analytical answers for the partial reaction-diffusion-adhesion equations for both time and space. If the balances allowed via the goal calculations permit the determination of Lie transformations, then we can reduce slight fractional variance calculations to normal variance calculations containing fractions. We suggest a different approach to find the numerical and analytical answers beginning from the numerical and analytical answers in the spatio-temporal fractal adhesion-diffusion-interaction model. Recent findings on the adhesion-diffusion interaction equation were obtained by the authors. Separate adhesion-diffusion reaction equations for partial temporal and spatial variables were presented.

The excellent accuracy of the suggested approach makes it a useful instrument for solving a Wide category of fractional differential equation problems. The numerical results show its effectiveness and applicability.
