    Abstract Synthesis of micro- and nano-sized crystalline BaFeO4 particles by precipitation from the electrochemically synthesized potassium ferrate(VI) solution by means of barium hydroxide and its encapsulation in paraffin wax were explored using scanning electron microscopy, X-ray diffraction spectroscopy and FTIR spectroscopy. Experimental results showed effective synthesis of the micro-sized and nano-sized BaFeO4 particles and their coating by the paraffin wax layer. The encapsulated micro- and nano-sized particles of BaFeO4 were applied in investigating the possibility of degradation of pesticide clomazone in water. The removal of clomazone from water by oxidation using encapsulated BaFeO4 could be almost 95%.

    Abstract Gas sensitive cerium oxide-tungsten oxide core-shell nanowires are synthesized and integrated directly into micromachined platforms via aerosol assisted chemical vapor deposition. Tests to various volatile organic compounds (acetone, ethanol, and toluene) involved in early disease diagnosis demonstrate enhanced sensitivity to acetone for the core-shell structures in contrast to the non-modified materials (i.e., only tungsten oxide or cerium oxide). This is attributed to the high density of oxygen vacancy defects at the shell, as well as the formation of heterojunctions at the core-shell interface, which provide the modified nanowires with 'extra' chemical and electronic sensitization as compared to the non-modified materials.

    Abstract The possibility of removing pharmaceuticals from aqueous solutions was examined using ibuprofen (Ibu) oxidation as an example, using in situ electrochemically synthesized ferrate(VI), a strong oxidant and coagulant, with forming of non-harmful byproducts. A solution of ibuprofen of 206 mg/L in 0.1 M phosphate buffer solution was treated with different amounts of fresh, electrochemically synthesized ferrate(VI). The changes of ibuprofen concentration in samples were determined using a UV-Vis spectrophotometer. The extent of mineralization was estimated using the changes in chemical oxygen demand (COD) values and total organic carbon (TOC) values of test samples. The largest reduction of the concentration of Ibu (41.75%) was obtained by adding 69.2 mg/L ferrate(VI) as Fe (Ibu: Fe = 1: 0.34). An effective removal of ibuprofen from aqueous solutions was recorded up to 68% and it can be done by using ferrate(VI) in the ratio Ibu: Fe = 1:3 as Fe. The possibility of ibuprofen removal by ferrate(VI) was confirmed by COD and TOC results, which demonstrated reduction up to 65% and 63.6%, respectively.

    Abstract This paper shows the effects of ferrate(VI) application in the treatment of industrial wastewater effluent in laboratory conditions. Samples used are a mixture of wastewater effluent from various industrial plants whose composition was determined by analyzing samples before the ferrate(VI) treatment. Determining physical-chemical characteristics of the samples showed very high chemical oxygen demand (COD) and the concentrations of individual pollutants are higher than the maximum allowed. In the tested samples, the COD was from 18 (sample 1) to 580 times (sample 2) greater than allowed (allowed 45 - 150 mg/l), while the concentrations of certain metals were several times higher than allowed (Cu allowed 0,1 mg/l, Zn allowed 0,2 mg/l). Also, a high concentration of total phosphorus content (allowed 2 mg/l) and fluoride was found (allowed 20 mg/l), 2-3 times higher than permissible. The applied Na2FeO4 was synthesized by electrochemical method and applied in situ. Physical-chemical testing of samples, after treatment with different amounts (2, 5, 8, and 10 ml) of Na2FeO4, concentration of 8 g/l showed that ferrate(VI) can be used as a multifunctional agent in the purification of industrial wastewater, where in the amount of contaminating matter is reduced below the maximum permitted level. It was demonstrated the high efficiency of ferrate(VI) as a strong oxidant in the removal of total P and suspended materials. Also pointed out was the high sorption power of the generated ferric(III)hydroxide, which with its developed surface absorbs 95,5% of the F- and removes it from the solution in the form of sludge. Showed a high efficiency of ferrate(VI) in the total removal of P (70 to 99,5%), and F- (89 to 95,5%), but depending on the presence of the total COD value or the presence of the total organic substances. At high values of the COD major part of ferrate(VI) is consumed in the oxidation of organic material and the formation of Fe(OH)3, which accelerate the process of decomposition of ferrate(VI), which contributes to lower the efficiency of the removal of P and F-.
