“…Thermodynamic parameters are critical to reveal the feasibility and characteristic of the adsorption system. Table 3 illustrates the obtained thermodynamic parameters at various temperatures ranging from 288 K to 318 K. All negative values of Δ G within the investigated temperature expressed the spontaneity of adsorption process [15, 21]. The Δ G values in absolute terms enlarged with the rising of temperature.…”

In this study, polypyrrole (PPy) was introduced into durian rind (DR) by in situ polymerization method to prepare durian rind/polypyrrole (DR/PPy) composite. The resulting material was characterized using scanning electron microscope (SEM), transmission electron microscope (TEM), infrared spectroscopy (IRS), and X-ray diffraction (XRD). Then, the removing performance of the DR/PPy material for anionic dyes was explored. The impact of key variables such as the amount of adsorbent, initial dye concentration, pH, adsorption temperature, and contacting time on the adsorption efficiency was examined. The result disclosed that the adsorption efficiency of DR/PPy for methyl orange, sunset yellow, and amaranth was satisfactory. In pH of 7, initial concentration of 100 μg mL-1, and DR/PPy dosage of 1.5 g L-1, the removal efficiency reached 97.31%, 98.48%, and 98.20%, respectively. The adsorptive kinetics and thermodynamic process were analyzed subsequently. The adsorption of anionic dyes on DR/PPy conforms to the pseudo-second-order kinetic and Langmuir isotherm models with maximum adsorption capacity ( q m , max ) of 193.05, 171.23, and 147.71 mg g-1 for methyl orange, sunset yellow, and amaranth, respectively. Finally, a possible mechanism involved in the adsorption system was put forward. This study implies a reasonable feasibility for the effective utilization of waste to control the pollution.

In the present study, the starch films with biosynthesized ZnO nanoparticles were obtained. The films obtained were examined for mechanical properties, environmental toxicity and biodegradation. It was observed that the addition of the ZnO nanoparticles to the polymer matrix caused an increase in the tensile strength and elongation at break. The STEZHP film was characterized by the elongation value at 306 (%). The addition of the nanoparticles had a positive influence on the degradation improvement of the films in question under the three different conditions applied. In turn, the presence of ZnONPs caused an increase in the toxicity of the materials investigated. In the case of the tests for toxicity towards plants, it was observed that the films (SAZ, SAZHP, SAEZ, and STZ) showed very little toxicity, as well as a weak correlation between the parameters of the film quantity and the shoot growth inhibition.

The presence of pharmaceuticals in ecosystems is a major health issue, calling for advanced methods to clean wastewater before effluents reach rivers. Here, we review advanced adsorption methods to remove ibuprofen, with a focus on ibuprofen occurrence and toxicity, adsorbents, kinetics, and adsorption isotherms. Adsorbents include carbon- and silica-based materials, metal–organic frameworks, clays, polymers, and bioadsorbents. Carbon-based adsorbents allow the highest adsorption of ibuprofen, from 10.8 to 408 mg/g for activated carbon and 2.5–1033 mg/g for biochar. Metal–organic frameworks appear promising due to their high surface areas and tunable properties and morphology. 95% of published reports reveal that adsorption kinetics follow the pseudo-second-order model, indicating that the adsorption is predominantly governed by chemical adsorption. 70% of published reports disclose that the Langmuir model describes the adsorption isotherm, suggesting that adsorption involves monolayer adsorption.
