Using the deep oxidation process with Fenton?s reagent to remove formaldehyde from industrial wastewater

Andrzej ŁODYGA ? Fertilizer Research Institute, Puławy, Poland; Dorota MINDA-DATA? Grupa Azoty, Poland; Magdalena KOZIOŁ, Piotr TYŃSKI ? Fertilizer Research Institute, Puławy, Poland Please cite as: CHEMIK 2013, 67, 7, 648?653 Abstract: Oxidation reaction with use of Fenton?s reagent is one of the most efficient and common methods of removing organic compounds from industrial wastewater. Fenton?s reagent is a mixture of Fe2+ and H2O2 ions and a source of hydroxyl radicals (OH?) with a high oxidizing potential. The paper presents examinations of Fenton process...

Soybean meal enriched with Cu(II) by biosorption ? a new product for animals

Zuzanna WITKOWSKA, Katarzyna CHOJNACKA, Mateusz SAMORAJ, Łukasz TUHY ?Institute of Inorganic Technology and Mineral Fertilizers, Faculty of Chemistry, Wroclaw University of Technology, Poland Please cite as: CHEMIK 2013, 67, 7, 642?647 Abstract: The aim was to develop a new generation feed additive with copper using the biosorption method. The process was conducted in a fixed-bed reactor with capacity of 2.5 dm3. Soybean meal constituted the matrix for microelement ions. The bed was enriched by pouring the solution with Cu(II) ions at concentration of 300 mg/dm3...

Seaweed extracts as biostimulants of plant growth: review

Łukasz TUHY, Jolanta CHOWAŃSKA, Katarzyna CHOJNACKA ? Institute of Inorganic Technology and Mineral Fertilizers, Faculty of Chemistry, Wroclaw University of Technology, Poland Please cite as: CHEMIK 2013, 67, 7, 636?641 Abstract: For increased efficiency of plant cultivation, new methods basing on seaweed extracts as biostimulants of plant growth are applied. Due to the presence of many biologically active compounds, seaweed extracts are widely used as plant stimulants. Thanks to bioactive substances, algae extracts can regulate the growth and development of plants. Application of seaweed...

West Pomeranian University of Technology in Szczecin, Department of Land Cultivation and Environmental Chemistry, Faculty of Environmental Management and Agriculture Please cite as: CHEMIK 2013, 67, 7, 620-627 Abstract: Four fertiliser mixtures were prepared from industrial sewage sludge from ?Police? Chemical Plant SA, municipal sewage sludge from the Municipal Wastewater Treatment lant in Stargard Szczeciński, the mixture of sawdust from coniferous and deciduous trees (in 1:1 ratio), iron (II) sulphate (VI) 7-hydrate, and urea. The mixtures underwent granulation. The factor...
