New Ni(II) coordination polymers with insulating and anticorrosive properties
Environmental Engineering and Management Journal › Vol. 6 › Nr. 2 A series of new Ni(II) poly-phosphinates have been synthesised using Ni(II) acetylacetonate as nickel precursor and a succession of ligands derived from phosphinic acid: ethyl-butyl-phosphinic acid, ethyl-butyl-thio-phosphinic acid, and respectively ethylbutyl-di-thio-phosphinic acid. Chemical analysis gel-chromatography, infrared spectroscopy (IR), spin electronic resonance (RES), X-ray diffraction (XRD), thermal gravimetric analysis (TGA), electrical resistance measurements at different temper...

Leptospirosis:clinical and environmental aspects of the Iaºi county
Environmental Engineering and Management Journal › Vol. 6 › Nr. 2 During 2005 and 2006, in the Infectious Diseases Hospital in Iaºi, there were admitted 26 patients suffering by Leptospirosis. The clinical investigations followed the tests of inflammation, the renal and hepatic proofs, the cefalo-rahidian liquid’s aspect, the ELISA Leptospirosis serum tests etc. The Leptospirosis etiology shown that on 50% of the patients, the affection was owed to L.ichterohemoragiae. The average cost of the treatment for a patient was evaluated as around 1000 Euro. The pa...

Removal of zinc (II) from aqueous solutions by romanian sphagnum peat moss
Environmental Engineering and Management Journal › Vol. 6 › Nr. 3 In recent years the removal of toxic substances especially heavy metals from water and wastewater by using of non-conventional low-cost sorbent (industrial wastes and some natural material including microorganisms, plant-derived materials, agricultural products and by-products, mineral oxides, clays) has received much attention. In this paper efficiency of Zn (II) removal from aqueous solutions by sorption onto Romanian sphagnum peat moss was studied in batch experiments involving process parame...

Removal of cadmium (II) from aqueous solutions by sphagnum moss peat: Equilibrium study
Environmental Engineering and Management Journal › Vol. 7 › Nr. 1 AbstractCadmium is listed by US-EPA as one of priority pollutant and as a known carcinogen, and therefore its removal from wastewaters of various industrial processes is a very important environmental problem. The paper analyzes the effectiveness of a Romanian sphagnum moss peat as available and cheaper sorbent in removal of Cd (II) from aqueous solutions. Batch sorption experiments were carried out in order to establish the influence of solution pH, peat dose, contact time and initial cadmium c...

Study on new complex compounds of Ti(IV) and Zr(IV) in aqueous solutions: synthesis, stability and application in cleaner technologies of natural leather
Environmental Engineering and Management Journal › Vol. 7 › Nr. 3 AbstractIn this paper, the study of synthesis and stability in aqueous solutions of new coordination compounds of Ti(IV) and Zr(IV) with ligand N-hydroxy-succinimide is presented. The salts: TiOSO4·2H2O and ZrOCl2·8H2O used for obtaining the studied coordination complexes, can derive from recycling metallic residues resulted in mechanical technologies applied for titanium and zirconium in S.C.

Recovery of some inorganic compounds from the sludges resulted after the leaching of uranyl ions from uranium ores
Environmental Engineering and Management Journal › Vol. 7 › Nr. 4 AbstractIn this work it had been tested the recovery of some compounds like: Fe2O3, TiO2, PO4 3- ions, Al2O3 from the sludges, which result in the industrial facilities for output of pure uranium dioxide. Solubilization of the chemical compounds from the uraniumwastes was performed in strong acidic media, using adequate methods....
