“…Adsorption characteristics that impacted the adsorption process were studied using a UV-Vis spectrophotometer. The initial phenol concentration was changed (50, 100,125, 150 mg L-1), pH (3,6,9,12), and temperature range (25,35,45, and 55°C ) To study the effect of variables on adsorption. The Minitab software's design of the experiments option's upper and lower range was used to calculate the total number of experiments.…”

Bentonite from Iraq was the clay of choice for this study (Calcium base). The “State Company of Geological Survey and Mining” provided this rock, which was altered using Activation by Heat and Acid. Heat activation involved calcination at 400 Celsius, whereas chemical Activation involved H2SO4. Analysis utilizing XRD, BET, and FTIR on bentonite before and after Activation. Adsorption kinetics and isotherm were analyzed to assess whether modified bentonite could act as an adsorbent to eliminate phenol from water. The study found that after being activated, bentonite’s surface area increased from 63.32 to 78.65 m2/g. The extraction of phenol from synthetic wastewater using activated bentonite was tested in a batch experiment. The effects of pH, concentration, and temperature on removal have been studied. According to the findings, pH of 3 is optimal for phenol removal, with an optimal elimination rate of 88% at 50 ppm, 55 0C temperature, and 1 gram of bentonite. The isotherm study indicates the Freundlich model has the most accurate model, with an accuracy of 97%. The experimental RSM was used to develop a statistical model with a remarkable 90% accuracy.

“…Human activities frequently lead to polluted water sources [1]. Phenol is released from textile, rubber, pulp and paper, plastics, pharmaceutical, coke manufacture, petroleum refineries, and ferrous sectors exceed safe levels [2]. Phenol is readily absorbed via skin contact, inhalation, or ingestion [3].…”

The removal of phenol from wastewater has become a significant environmental concern because of its toxicity, even at low concentrations. This research focuses on the removal of phenol using spent tea leaves (STLs) as an adsorbent. SEM and FTIR tests were used to evaluate the surface characterization of the STLs. The effect of the parameters such as initial phenol concentration (20 - 80 mg. L-1), pH (3 - 12), temperature (25 - 55 °C), contact period (30-330 min), and dose (0.25 - 2.5) on the removal of phenol was studied. The highest removal of phenol of 82% was obtained at 20 mg. L-1 of initial phenol concentration, 4 h of the contact period, pH of 3, adsorbent dose of 2 g, and temperature of 55 °C. The results of the kinetic study fitted the pseudo-second-order model. The obtained data for phenol adsorption isotherm fitted to the Langmuir, Freundlich, and Temkin models. The Temkin isotherm model presented the best fitting with phenol adsorption isotherm experimental data based on the correlation coefficients. According to the findings, the STLs can effectively remove phenol from wastewater.

Most dental supplies don't seem to be much of a barrier against germ infiltration. Therefore, the filling must be done with perfect caution and high antimicrobial effectiveness. When dental erosion occurs due to germs that lead to caries, a dental filling is used, creating a small microscopic space between the dental filling and the root end infiltration. This allowed the tooth to be penetrated for the second time, which was the research problem. Adding two compounds to antibacterial fillers (zinc polycarboxylate cement) made them work better: Firstly, was zinc oxide (ZnO) that was made chemically, and secondly, was green ZnO nanoparticles that were made from orange peels and mixed with ZPCC in different amounts. The study was conducted on the formed nanocomposite using FTIR, UV-vis, FESEM, sitting time, and antibacterial measurements. The biological activity was tested using Staphylococcus aureus, Escherichia coli, and Candida albicans.
