Polycyclic aromatic hydrocarbons (PAHs) represent a large class of persistent organic pollutants in an environment of special concern because they have carcinogenic and mutagenic activity. In this paper, we focus on and discuss the effect of different parameters, for instance, initial concentration of Anthracene, temperature, and light intensity, on the degradation rate. These parameters were adjusted at pH 6.8 in the presence of the semiconductor materials (TiO2) as photocatalysts over UV light. The main product of Anthracene photodegradation is 9,10-Anthraquinone which isidentified and compared with the standard compound by GC-MS. Our results indicate that the optimum conditions for the best rate of degradation are 25 ppm concentration of Anthracene, regulating the reaction vessel at 308.15 K and 2.5 mW/cm2of light intensity at 175 mg/100 mL of titanium dioxide (P25).

A series of Cu(II), Fe(III), Pb(II), Mn(II) metals complexes have been synthesized with the new thiazole azo dye containing tridentate [N.N.O] donor ligand 2-[2− -(5-nitro thiazolyl) azo]-4-methyl-5-nitro phenol (5-NTAMNP) derived from 2-amino-5-nitrothiazole and 3-methyl-4-nitrophenol by the diazotization operation and the adizonium chloride salt solution of 2-amino-5-nitrothiazole reacting with 3-methyl-4-nitrophenol as a coupling compound in alkaline alcoholic solution. The structures of synthesized novel ligand was identified and confirmed via resorting to various spectroscopic techniques which included, 1H NMR, Mass spectrum, UV–visible, Fourier-transform infrared (FTIR), X-Rays diffraction (XRD), the surface nature and morphology and size average and elemental composition of individual ligand particles were examined using a field emission scanning electron microscope (FESEM) coupled with an energy dispersive X-ray system (EDX), in addition to above the physical properties of ligand have been studied via check its melting point and the purity of the ligand also was checked by TLC in presence of a certain solvent system. As for the consistency positions available in (5-NTAMNP) and the manner of its association with these metallic ions it’s likely that the pattern of complexity as a tridentate chelating agent with the formation of a coordination number for all metallic ions found equal to six and have Octahedral shape for all metallic ion. The optimal condition for complexation have been studied, the prepared metallic complexes were identified via UV–visible & FT-IR spectra. All metallic complex and (5-NTAMNP) ligand were screened for their biological activities.

S EVERAL parameters have been studied in this manuscript to investigate the effect of certain conditions on the removal and the decolorization of the textile dyes: reactive yellow 14 (RY 14) and reactive green (RG) dyes from aqueous solution. Parameters such as temperature, initial concentration of dye and initial pH were taken into consideration to reach the perfect removal and decolorization for both dyes. This work was achieved in both dark and photoreaction processes. In dark reaction, the type of adsorption was determined based on Gibb's free energy values, activation energies and change in enthalpies, which were found that the physical adsorption for removal of both dyes is predominated, and the reaction is exothermic. The adsorption capacity and percentage of removal both dyes elevated with raised the dye concentration. The best initial pH for removal of RY 14 and RG dyes dyes was conducted and found equal to 5.14 and 9.75 respectively. The raised in temperature is not enhanced the adsorption process, that due to the dark reaction for both dye is exothermic. The small negative values of change in entropies are proved the associative mechanism of both dyes on ZnO surface. On the other hand, the results under the percent UV-light showed, that the optimal conditions were found at 303.15 K, with 25 ppm and optimum pH=11.01 for reactive green(RG) dye, while the optimum conditions were appearing at 50 ppm and best pH= 6.075 for reactive yellow 14 at same temperature. The decolorization process for both studied dyes was found to be a pseudo-first-order kinetic, fast (low activation energies), endothermic reaction (positive change in enthalpies), non-spontaneous (positive change Gibbs free energies) and less random (negative change in entropies). The photoreaction is a completed to removal process to depress the toxicity for these studied textiles dyes.

To improve the therapeutic efficacy of Mebeverine Hydrochloride (MB.HCl) medication, this study was worked on by reducing the drug dosages while maintaining the level of the drug inside the patients’ body. The best treatment results are achieved by loading the drug through a medicated drug carrier that is Chitosan nanoparticle (CSNPs) and preparation was done by Ionic gelation method which including reaction between binding material Sodium tripolyphosphate (STPP) and Chitosan (CS) which was extracted from shrimp shells. The drug was loaded by Chitosan nanoparticles and the proof was done by using several techniques, namely FT-IR and X-ray diffraction spectrum, the size of particles was determined before and after loading using Particle size analyzer, also use the FE - SEM emission electron scanning microscope where the results showed the success of preparing a drug carrier and MB.HCl was loading on Chitosan nanoparticles.

This work studied the amalgamation and portrayal of another Azo-Schiff base ligand and its utilization of zinc in certain medications. Azo 2-(E)- (1H-benzo[d]Imidazol-2-yl)diazenyl)- 5-((E)- (4-Chlorophenylimino)methyl)phenol.(BIACMebp) has been incorporated after the closely resembling system and Al-Adilee et.al., with some adjustment in a two-venture measure, in the initial step, 2-Amino benzimidazole (1.33 g) was blended in with hydrochloric corrosive 3ml In (thirty mL) refined water and diazotized under 5 °C with sodium nitrite NaNO2 (0.75 gm,0.01mol, broke up in 20 ml refined water) was included drops, and in the next step the diazonium chloride compound is then combined with 3-(4-Chlorobenzylideneamino)phenol(CBAP) (2.31 gm,0.01 mol), disintegrated in combination from 60 ml ethanol and 18 ml sodium hydroxide(5%) Pour the blend for 1 hour at a temperature of 5-0 m. The readied azo where inspected by various phantom procedure in wording, C.H.N natural investigations, metal substance, FT-IR, UV-Vis, 1H-NMR and mass spectra contemplates. The metal ligand proportion (M:L) in alcoholic watery arrangements controlled by mole proportion methodand it demonstrates 1:1 for the complex. Additionally, the strength constants for the complex with zinc has been determined frightfully by UV-Vis technique. All outcomes show this complex has high strength. The systematic applications have been achieved in medication (zinc sulfat) for several companies (zincodin (Aktive) 25 mg, Zinc (Kontam) 35 mg, Zinc Sulfate (Jink.) 20 mg.
