Contamination of heavy metal (Cd2+ & Pb2+) ions in drinking water is producing major impacts on the environment and public health considered one greatest dangers to humanity. Membrane technology has been chosen over other processing methods due its simplicity high capacity for more effective removal hazardous metals. In current study, amine, thiol, bi-thiol functional groups were used functionalize mesoporous silica nanoparticles (MSNs) improve efficiency nanoparticle. The morphology MSNs as...
Low-cost natural materials-mediated adsorbents for the removal of dye pollutants from water are gaining popularity over chemical due to their eco-friendliness, widespread availability, and ease manufacture. A CaO-derived eggshell was used alter surface zinc-manganese-ferrite (Zn0.6Mn0.4Fe2O4) nanoparticles by post-precipitation method. The CaO/Zn0.6Mn0.4Fe2O4 nanocomposite studied using FT-IR , XRD SEM, utilized Rhodamine B dye. adsorption efficiency 10 mg L-1 RhB reached 75% at pH 4.0, 60...
Abstract A world without plastics is unimaginable now and probably also in future. With the growing use of plastic, problem waste plastic disposal growing. Recycling a promising option to avoid serious environmental challenge caused by them. Among various options for recycling, catalytic conversion hydrocarbons very attractive. Catalytic pyrolysis depolymerizes an oil which can be used as liquid fuel. This sustainable way utilize waste, simultaneously meet energy demand. We studied sulphated...
Two novel complexes, [(C7H10NO2)CdCl3]n(I) and [(C7H9NO2)CuCl2],havebeen synthesized characterized. Single crystal X-ray diffraction revealed that in compound (I), 2,6-dimethanol pyridinium acts as a monodentate ligand through the O atom of hydroxyl group. Contrarily, pyridine interacts tridentately with Cu(II) ion via nitrogen atoms two oxygen (O, O') groups. The structure's intermolecular interactions were studied using contact enrichment ratios Hirshfeld surfaces. Following metal...
A new magnetic P. harmala biochar/Mn-ZnFe2O4 material was prepared by the one-step pyrolysis approach and characterized FT-IR, SEM, XRD, BET techniques. The efficacy of removing rhodamine B (RhB) via adsorption catalytic degradation examined. Adsorption removal attained 82% 10 mg·L-1 RhB at pH 4.0, 90 min agitation, 3.2 g·L-1 adsorbent. kinetics indicated a diffusion-limited mechanism matched second-order model. equilibrium data are better suited Langmuir isotherm, maximum monolayer capacity...
The alkylation of benzene with propane to yield isopropylbenzene proceeds high selectivity over bifunctional metal–acid catalysts comprising Pt and Keggin heteropoly acid in a fixed-bed reactor at 250–350 °C 1 bar pressure. Most efficiently the reaction occurs Pt/H4SiW12O40/SiO2 catalyst 300 °C, giving 90–93% 6–8% conversion, significantly exceeding efficiency previously reported Pt/HZSM-5 catalyst. through pathway including dehydrogenation propene (1) on sites followed by (2) sites. At...
Membranes are an efficient way to treat emulsified heavy metal-based wastewater, but they generally come with a trade-off between permeability and selectivity. In this research, the amine sulphonic groups on inner outer surface of mesoporous silica nanoparticles (MSNs) were first modified by chemical approach. Then, MSNs utilized as new inorganic nanofiller fabricate mixed matrix polysulfone (PSU) nanocomposite membranes using classical phase inversion The resultant characterized their...
Using acid–base assays and simple slow evaporation method at ambient temperature, we were successful in producing a novel salt with the chemical formula (C5H14N2)[HgCl4]·H2O. According to single-crystal X-ray diffraction data, crystal packing was regulated by H-bonds Coulomb interactions (also called electrostatic interactions) between distinct entities, which formed 3D network. The 2D fingerprint plots Hirshfeld surface utilized examine effect of intermolecular interactions. FTIR...
