The contribution determined...

The possibility of removing pharmaceuticals from aqueous solutions was examined using ibuprofen (Ibu) oxidation as an example, in situ electrochemically synthesized ferrate(VI), a strong oxidant and coagulant, with forming non-harmful byproducts. A solution 206 mg/L 0.1 M phosphate buffer treated different amounts fresh, ferrate(VI). changes concentration samples were determined UV-Vis spectrophotometer. extent mineralization estimated the chemical oxygen demand (COD) values total organic...

In vitro antibacterial activity tests of seven biofungicides (Ekstrasol, Bisolbisan, Bisolbifit, Serenade, Sonata, Timorex, F-Stop) and two disinfectants (colloidal silver alone in combination with hydrogen peroxide) against the Pseudomonas tolaasii strain (NS3B6) were carried out by disc-diffusion, broth microdilution macrodilution method. Biofungicides tested this study did not exhibit any antimicrobial neither one methods used. Disc diffusion method revealed high sensitivity P. to Ecocute...

In recent years, considerable attention has been paid to various applications of Fe(VI) due its unique properties such as oxidizing power, selective reactivity, stability the salt, and non-toxic decomposition by-products ferric ion. environmental remediation processes, proposed green oxidant, coagulant, disinfectant, antifoulant. Therefore, it is considered a promising multi-purpose water treatment chemical. also potential in electrochemical energy source, 'green cathode'. The effectiveness...

Abstract The effect of microstructure modifiers, Sn and Ag, on the corrosion rate commercial Pb–Ca alloy in H 2 SO 4 electrolyte was investigated by potentiodynamic polarization weight loss measurement at open circuit potential. modification alloy, provoked alloying with tin silver as well proper thermo‐mechanical treatment, is recorded optical microscopy. experiments have shown three‐ to five‐fold decreases ternary Pb–Ca–Sn quaternary Pb–Ca–Sn–Ag alloys, compared results for primary alloy....

The oxidation of iron compounds from alkaline 10 M KOH electrolytes on a boron doped diamond electrode is examined by cyclic voltammetry between the potentials hydrogen evolution reaction and oxygen reaction, due to ferrate(VI) electrochemical synthesis. It shown that anodic current peak appears in free electrolyte at less positive potential than probably coincides with >CH2 groups C-sp2 graphite impurities formation >C=O C-sp3 structure. Addition Fe(III) provoke wave voltammograms region...

The oxidative and coagulation efficiency of Na2FeO4 solution, electrochemically generated by trans-passive anodic oxidation electrical steel in 10M NaOH is confirmed the process purification heavily contaminated wastewater from coal separation plant. decontamination evaluated comparing values selected contamination parameters obtained chemical biochemical analysis plant effluent water after with ferrate(VI) solution relatively simple laboratory procedure. sample 450 ml treated conditions...

In part I [1] of the investigation behavior iron and selected low carbon steels in concentrated (10M - 15 M) water solution NaOH KOH wide range electrode potentials, between hydrogen evolution reaction oxygen reaction, is investigated discussed. On base experimental data obtained by LSV galvanostatic pulse methods, it concluded that efficient synthesis ferrate (VI) can be expected region anodic potentials + 0,55 V 0,75 against Hg|HgO reference electrode. this paper optimization electrolysis...

This paper shows the effects of ferrate(VI) application in treatment industrial wastewater effluent laboratory conditions. Samples used are a mixture from various plants whose composition was determined by analyzing samples before treatment. Determining physical-chemical characteristics showed very high chemical oxygen demand (COD) and concentrations individual pollutants higher than maximum allowed. In tested samples, COD 18 (sample 1) to 580 times 2) greater allowed (allowed 45 - 150...

The soil-borne pathogen Cladobotryum dendroides causes cobweb disease of button mushroom (Agaricus bisporus) and its significant yield losses. Casing soil disinfection by toxic formaldehyde is a widespread practice. aim this study was to investigate the potential two environmentally friendly substances, colloidal silver peracetic acid, against C. dendroides. Their biological efficacy (impact on yield), effectiveness (disease control) type interactions between them fungicide...

The electrochemical methodologies for synthesis of BaFeO4 and Ag2FeO4 are presented in this article. first step was to prepare a solution the K2FeO4 as starting reagent by anodic dissolution transpassive potential region electrical steel 10M KOH. current density applied fixed at 20 mA/cm2 55?C. Solid were precipitated from addition Ba(OH)2 8H2O AgNO3 solutions, respectively. yield solid salt synthesized calculated hromitne titration, while their phase composition determined XRD analysis....

The realization of the concept sustainable development is conditioned by impact human activities on natural resources, both renewable and nonrenewable. basic areas that enable are: food security, energy supply environmental protection. Protection use water as most important resource a problem present in all these areas. In process production, raw material means work, protection, preservation quality protection from pollution, well purification, problem. constant increase number inhabitants...

Silver is a known disinfectant from ancient times, and it has been widely used for various purposes: food water disinfection, curing of wounds as universal antibiotic wide spectrum diseases - until the Second World War discovery penicillin. Until recently, was assumed that silver, being heavy metal, toxic humans living beings. However, newest research provides facts usage even drinking benign if added in small concentrations (in parts per billion). It shown newer scientific technical...
