Turbidity Removal by Electrooxidation from Pistachio Processing Wastewater Using Ti/Pt Anodes

Turbidity is the presence of suspended substances in water and is a pollution parameter for water. In this study, the removal of turbidity from pistachio processing wastewater by the electrooxidation process was investigated. Ti/Pt was used as the anode material and stainless steel was used as the cathode material. Stirring speed, supporting electrolyte type, and supporting electrolyte type concentration, initial pH value, and current density were investigated as working parameters. The mixing speed was investigated at 0, 200, 400, and 600 rpm. NaCl, KCl, Na2SO4, and NaNO3 were used as support..read more

Demonstration of Efficient Separation, Surface Investigation and Thermodynamics Study of Sodium4-[(4-dimethylamino) phenyldiazenyl) Benzene Sulphonate Dye from Aqueous Solution onto Acid Activated Modified Purple Knight

The organic dye pollution has become increasingly serious in recent years and removal of organic dyes from the water samples has received intense attention. In present work the acid modified purple knight (Alternanthera dentata) leaves powder (MALP) is used as an adsorbent in order to remove sodium 4-[(4-dimethylaamino) phenyldiazenyl) benzene sulphonate (methyl orange dye) from an aqueous solution. The absence of stretching vibrations (1008cm-1 , 1400cm-1,1600cm-1 and 3184cm-1) of characteristic functional groups of modified purple knight plant in FTIR-analysis, as well as a significant decre..read more

Preparation and Catalytic Performance of the Copper-Manganese-Silicon Catalysts for Dehydrogenation Reaction of 2-butanol

Cu-Mn-Si catalysts with copper-manganese oxides as the main constituents and silica dioxide as the supports were prepared by co-precipitation method. The performance of the catalysts for the dehydrogenation reaction of the 2-butanol to methyl ethyl ketone was tested. The effects of Cu and Mn ratios on the catalytic performance were investigated. The catalysts were characterized by XRD, SEM, H2-TPR, TG, BET and XPS, to reveal the catalytic mechanism. The results showed that after adding the manganese, the copper-manganese complexes were formed in the catalysts, which effectively improved the ac..read more

Green Synthesis, Characterization and Thermal Investigation of Ni(II) and Cu(II) Complexes Constructed by Pyridine-2,6-Dicarboxylic Acid

Two complexes [Ni(pda)(H2pda)]·3H2O (1) and [Cu(pda)(H2pda)] (2) containing pyridine-2,6-dicarboxylic acid (H2pda) were synthesized by room-temperature solid state reaction and characterized by elemental analyses, powder X-ray diffraction (PXRD), single crystal X-ray diffraction and infrared spectroscopy. The powder complexes were confirmed as single phase with their PXRD. The thermal property was studied using simultaneous thermogravimetry and differential scanning calorimetry (TG-DSC) techniques. The complexes were decomposed in several stages and the final products of their thermal decompos..read more

Synthesis, Characterization, DFT Calculations and Anticoagulant Activity of Symmetrical and Unsymmetrical N-Aryl Thiourea Derivatives

The present study reports a methodology for the synthesis of symmetrical and unsymmetrical thiourea derivatives 1-9, which have been prepared in good overall yields from condensation reactions between phenylisothiocyanate and different primary amines. The structures of all products were confirmed by the spectroscopic analysis (UV, IR, and NMR). These derivatives were tested for anticoagulant activity using PT and APTT reagents, and those reagents are considered also a controller, the results showed that the theN-aryl thiourea derivatives have very high anticoagulant activity.

Synthesis, Characterization, Enhanced Solubility and Antioxidant Activity of the Inclusion Compound of 2-Amino-N-o-tolyl-benzamide and Beta Cyclodextrin

The objectives of this research, were to study the effect of beta cyclodextrin on the enhancement of the solubility and the antioxidant activity of 2-Amino-N-o-tolyl-benzamide (ATB). ATB was obtained by a new synthesis method and used to form inclusion compound macromolecule with -CD. The characterization of the ATB and the complex were subsequently established by FT-IR; 1H NMR; 13C NMR; NMR 2D spectra and XRD. The optical activity was measured. The interaction of β-CD and ATB was also analyzed by UV-Vis spectroscopy in order to determine the formation constant. The stoichiometry of the com..read more
