In developing countries, it still suffers from endless problems regarding wastewater treatment and the problem of choosing appropriate system due to lack proper technology weak economy. This study highlights maturity oxidation pond (stabilization) small communities as an effective, low-cost simple post-treatment technique for treating before discharging into aquatic ecosystem. The Rashid plant was cited a in city Rashid-ElBeheira Governorate - Egypt model applying this wastewater. work also...

Port Said Harbour is one of the main commercial harbours Egypt and locating under stress increased human activities with time. Accordingly, this study was used to identify water quality harbor indices for amount nutrients other pollutants enters marine environment. Five stations selected cover different characteristics seawater Harbour, Hydrochemical characteristics, Nutrient salt Heavy metal were investigated during winter summer as an indicator indices. The Eutrophication index (EI),...

Breast cancer is the second leading cause of death among women. The present study an effort to reveal antiproliferative and antioxidant actions mango seed kernel extract (KE), peel (PE), their combination (KEPE) on mammary tumors induced by 7,12 dimethylbenz[a]anthracene (DMBA). Seven groups adult female Sprague-Dawley rats were prepared, including C: (control), DMBA: (rats administered with DMBA), (DMBA-KE), (DMBA-PE), (DMBA-KEPE): DMBA then treated KE, PE, (both KE PE), respectively, (KE)...

Activated carbon and rice husk were successfully applied for the removal of Fe(III) Mn(II) ions from El-Umum drain water, Alexandria coast, Egypt. Langmuir Freundlich adsorption isotherms are to give fruitful results. The was best, as controlled Xm KF values.

Abstract Guava ( Psidium guajava ) seeds were used for the preparation of activated carbon (AC) using zinc chloride (GCZ36), phosphoric acid (GCH36), potassium hydroxide (GCK36), and one other sample was prepared without activation (GC36), carbonized 3 h at 600 °C. They added to cellulose acetate form hybrid membranes (Ms) phase inversion technique. The AC characterized by % ash content, weight loss on drying, nitrogen adsorption isotherm, TEM, XRD. FTIR SEM ACs Ms. GCK36 exhibited a higher...

Proline is water soluble amino acid extensively used in drug delivery systems. Compounds of cobalt (Co) transition metal have potent antimicrobial and anticancer activities. However, a system combining proline not reported yet. For the first time, new hybrid semi-organic single crystals chloride (PCC) are prepared. The novelty article also that crystal showed antitumor activity. Doping PCC by Ag0NPs significantly increased these biological anisotropic magnetic properties can mitigate...

Several sediment samples in Lake Burullus have been affected by the discharges of heavy metals through different drains. The study aimed to analyze chemical speciation these metals. In particular, forms Cd, Cu, Fe, Mn, Pb and Zn sediments collected spring season were studied using a sequential extraction method. In general, all elements recorded highest concentrations area near discharge point. data indicated that, under wide variety environmental conditions ranging from oxic fully anoxic...

New azo compounds containing barbituric acid, thiobarbituric acid or thiouracil, together with their complexes, were prepared.All the complexes are tetrahedral.Axial ESR spectra observed for a d x2Ày2 ground state small g || values indicating strong interaction between ligands and metal ions.Conductivity measurements proved semiconducting properties complexes.Energies of activation (ÁE ) order thermal reactions (n) calculated by DTA.

Abstract In this study, newly created hybrid cellulose acetate (CA) membranes were prepared using the phase inversion technique. Activated carbon derived from Helianthus annuus (sunflower) seed shells (SFAC) immersed in CA polymer casting solution, and produced used to treat contaminated water. Phosphoric acid was utilized as an activating agent with a ratio of 3:1 (wt.) for preparing SFAC7, SFAC8, SFAC9 activated carbons various carbonization temperatures (700, 800, 900°C, respectively). By...

Thirty-eight amino alcohol complexes were prepared and analyzed in the mole ratios 1 ; 1, 2 3 (M L). The IR spectra proved that coordination occurs via oxygen nitrogen atoms of ligands. nujol mull electronic absorption room temperature magnetic moment values are O h T d geometry. All complexes, except those Zn II , Cd Hg high spin with existence a Cu-Cu interaction copper complexes. ESR parameters calculated including c-bond parameter ( f ) fraction character Cu -4S ground state axial...
