Deals with the amoxicillin AMX removal trial using hydrogel. (F-TIR), (F.E-SEM), and UV-visible spectroscopy were used to describe the hydrogel of sodium alginate-g-poly (Acrylic acid-fumaric acid). The purpose of the adsorption investigation was to determine the impact of (10-100 mg L-1) conc. of AMX Optimization appear to have the best percentage percent removal at 97.40 percent at concentration 100 mg L-1, and contact duration 2hr. Take a look at two isotherm models. The second order model (R2= 0.9041) outperforms the Freundlich, Langmuir (R2= 0.9772), and three types of kinetic models (first order, second order, and Elchovich). پرونده مقاله -

Batch adsorption experiments were conducted to estimate the influence of several factors like pH solution, the concentration of CR dye, equilibrium time, adsorbent amount, and temperature solution. The top result correlation was found via the Langmuir model, and the best adsorption efficiency was 52.55 mg g–1 for CR dye. Thermodynamic studies appear that the adsorption of CR dye was feasible, endothermic, and spontaneous. Through the results, the prepared surface has very high efficiency in removing textile dyes and is environmentally friendly, inexpensive. پرونده مقاله
