In this Study, hydrogel P(CH/AA-co-AM) was prepared, identification and utilized as an efficient absorbent to eliminate Cr (III) and Cd (II) ions from the aqueous solution. The adsorption of these ions follows Freundlich isotherms. Due to greater activity surface of the hydrogel in adsorption of the contaminants, they can be utilized for elimination of the mentioned ions from water. Therefore, we characterized structural, surface and thermal properties of the prepared materials with technique: TGA, FE-SEM and FT-IR. Moreover, we implemented the kinetics of sorption with regard to the amounts of the metal sorbet at distinct time intervals and thus examined the modeling of the isotherm and kinetic curves. Finally, we computed the reaction order as well as rate constant.

Pomegranate peels are considered as solid agricultural residues that were used as adsorbent materials, very effective in get rid of brilliant yellow Dye from aqueous solution after converting it to Acid-Activated Carbon by phosphoric acid. The surface properties were studied through the use of (FTIR ) and (FESEM) techniques. Several factors affect the adsorption process have been studied like, effect of dye concentration (10-100 mg/L ), where the adsorption efficiency (Qe mg/g) increases with increasing dye concentration ( mg/g ) and weight effect (0.01-0.1 ), the adsorption efficiency(Qe mg/g) decreases with increasing surface weight. Desorption of the Brilliant yellow from the ACPP was studied utilizing several type of solvents (acetone 10% (v/v), methanol 10% (v/v), 0.1N HCl, 0.1 N NaOH,). The adsorption is found through the results that obeys the Friendlich isotherm because it depends on the value of (R2 ) and also the heterogeneous surfaces.

These hydrogels include surface SA-g-(PAAc-co-AM) hydrogel and its nanocomposite. The properties of the prepared hydrogels were studied using several techniques, including FESEM, TEM and XRD. Adsorption tests for these surfaces were performed on textile dyes including Brilliant green (BG), Methyl violate (MV), Malachite green (MG), Rhodamine B (RhB) and Brose Bengal (RB). We compared the surfaces of SA-g-(PAAc-co-AM) hydrogel, its nanocomposite and activated carbon (AC) as adsorbents. The best results of the percentage of removal (E%) of textile dyes were in the order of BG, RB, MV, MG and RhB. Arranging in the increasing order are as follows: SA-g-(PAAc-co-AM)/AC, SA-g-(PAAc-co-AM) and activated carbon (AC).

ZnO nanoparticles of rod-like architecture have excellent potential to be used in wastewater treatment as a photocatalyst. They were synthesized by utilizing sonochemical/hydration- dehydration techniques using glutamine as a biotemplate. The effects of calcination temperatures, that is, 300°C, 500°C, and 700°C, on the crystallinity, optical properties, and photocatalytic activity of synthesized zinc oxide nanoparticles were investigated. X-ray diffraction (XRD) results indicated that all calcinated samples have a crystalline hexagonal wurtzite structure. Morphology and elemental compositions were investigated using field emission-scanning electron microscopy with energy-dispersive X-ray spectroscopy. The XRD and Fourier transform infrared (FTIR) spectra revealed that the samples were amorphous at 100°C; however, it changed into a crystalline structure amid the calcination process. Optical properties were determined using a UV-visible reflection spectrophotometer and showed abatemen...

Environmental pollution is one of the most important and main problems that the world is facing today. Global production and use of chemical compounds, many of which are resistant to biodegradation, have increased significantly in recent decades. These compounds enter the environment after consumption, and therefore, it is necessary to provide solutions to reduce consumption and remove pollutants from the environment. Removing the textile dyes of crystal violet (CV) and methylene blue (MB) from aqueous solution by CNT/TiO2 surface was studied. We considered several physio-chemical parameters for example, contact time, primary concentration dye (5-50 mg L-1), adsorbent amount (0.01-0.1 gm), as well as temperature (15, 35, and 50 °C) in technique batch-adsorption. The output appeared absorbing two favorable dyes MB, CV at the basic pH. Moreover, removal present elevated by the increased amount of adsorbent, while decreased by uprising the primary concentration of dye, and agitation ti...

Pollution of water resources with various organic and inorganic pollutants is one of the biggest challenges of the present age. These infections seriously threaten human health and the lives of plants and animals. To minimize the mischievous effects of polluted water, technology-based smart treatment methods are necessary for sustainable equipping of drinking water. Application of (AAC-co-AM)-g-MCC hydrogels for the percentage removal of dye Methyl volute MV, from aqueous solutions have been studied.
