Because of the potential for reversible effects on living organisms and bacterial elaboration resistance, removing drugs from aqueous solutions is critical. 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

Discharge of dye-containing wastewater from various industries like textile, leather, paint, cosmetics etc. industries contributes to large amounts of pollution, leading to serious environmental problems such as quality deterioration of fresh water and endangering ecosystems' health. One of the conventional anti-fungal agent in aquaculture which should be eliminated from wastewaters prior to releasing it into natural water resources. Tremendous volumes of colored wastewater are generated in textile, leather, paint, cosmetics etc. industries, causing eternal damage to the water resources. Wastewaters released from dye production and application industries are responsible for water pollution. Untreated disposal of the colored water into receiving water body causes damage to aquatic life and human bodies. Due to the high toxicity of dyes at low concentrations, they must be treated before being discharged into the receiving body of water. Therefore, environmental legislation has imposed severe limits on the discharged effluents' concentrations from dyestuff manufacturing and textile industries. پرونده مقاله

The essential trace elements were very significant for the life of humans, and the imbalance in blood serum lead to so serious diseases. In this study, zinc (Zn) has been measured in the serum of 2005 samples (1305 male and 700 female) apparently healthy Iraqi persons aged 20-70 years using a flame atomic absorption spectrophotometer (FAAS). The mean concentration of Zn was (0.96 – 1.12 mg ml-1) in males and slightly lower (0.8 – 1.02 mg ml-1) in females. The concentration of Zinc was slightly increased by age, especially in the groups of 31-40 years, and slightly reduced in the group of 51-61 years. The concentration of zinc in all groups of the study seems to be stable. The study showed that there is a deficiency in Zn value (Zn concentration below 0.5 mg ml-1) in the male and females healthy populations by 22.9% and 18.85%, respectively. پرونده مقاله

This research addressed the elimination of the dye Congo red (CR) from an aqueous solution utilizing dried palm leaf activated carbon (PLAC). Therefore, we performed batch experiments for isotherms and sorption kinetics. According to the experimental data, the adsorption method largely depends on the equilibrium time, initial concentration of dye, pH solution, and adsorbent amount. We observed sorption equilibrium for the dye Congo red via PLAC in 60 min and an adsorption capacity of 52.1 mg g-1. A pseudo-first-order kinetic model was followed by sorption kinetics, whereas the Langmuir isotherm has been proposed to be help reache the equilibrium factor. The above data demonstrated that PLAC is an effective, low-cost, and environmentally friendly biomaterial for removing the dye from the aqueous solution. پرونده مقاله

This research studies the removal of textile dye (Congo red (CR)) from aqueous solution via using low-cost adsorbent prepared from GO/P (AA-co-AM) composite. 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
