TEST METHOD FOR DETERMINING THE CHEMICAL EMISSIONS OF A MARINE DIESEL ENGINE EXHAUST IN OPERATION
PublicationThe article briefly describes the problem of air pollution caused by sea-going ships and the resulting restrictions on the emission of toxic and harmful chemical compounds in the exhaust of marine engines, introduced by the International Maritime Organization (IMO) under the International Convention for the Prevention of Sea Pollution from Ships (MARPOL 73/78). Such emissions provide a significant metrological problem, not only...

Chemical Derivatization Processes Applied to Amine Determination in Samples of Different Matrix Composition
PublicationAmines are important biological compounds, and so their analysis and monitoring in various matrices is worthy of investigation and development.Due to the polar nature of amines, chromatographic analysis of free amines is generally unsatisfactory owing to adsorption and decomposition of the solute on the column, resulting in peak tailing and losses. Therefore, many derivatization reactions are employed to reduce the polarity, improve...

A New Approach to Chemical Recycling of Polyamide 6.6 and Synthesis of Polyurethanes with Recovered Intermediates
PublicationA new efficient method for the chemical decomposition of polyamide 6.6 by the glycolysis and amino-glycolysis processes was proposed. The glycolysis was conducted using the mass excess of ethylene glycol (EG) as a decomposing agent in the presence of a catalyst. Also, a mixture of EG and triethylenetetramine was used as another decomposing agent in the amino- glycolysis process. The described process of decomposition did not...

Phytoplankton communities of polar regions–Diversity depending on environmental conditions and chemical anthropopressure
PublicationThe polar regions (Arctic and Antarctic) constitute up to 14% of the biosphere and offer some of the coldest and most arid Earth's environments. Nevertheless several oxygenic phototrophs including some higher plants, mosses, lichens, various algal groups and cyanobacteria, survive that harsh climate and create the base of the trophic relationships in fragile ecosystems of polar environments. Ecosystems in polar regions are characterized...

Crystal structure, chemical bonding, and physical properties of layered AIrSn2 (A = Sr and Ba)
PublicationWe report the experimental and theoretical investigation of structure, chemical bonding interactions, and physical properties of new ternary stannides AIrSn2 (A = Sr and Ba). AIrSn2 (A = Sr and Ba) crystallizes in the orthorhombic Re3B-type structure with the space group Cmcm (No. 64). According to single-crystal X-ray diffraction results, the structure of AIrSn2 (A = Sr and Ba) can be considered as a Zintl-type compound with heterogeneous...

Study of Phase and Chemical Composition of Bi1-xNdxFeO3 Powders Derived by Pressureless Sintering
PublicationIn the present paper studies on Bi1xNdxFeO3 for x =0.1-0.4 are reported. The mixed oxide method followed with pressureless sintering was employed for ceramics fabrication. Thermal behavior of stoichiometric mixtures of simple oxide powders, viz. Bi2O3, Nd2O3 and Fe2O3 was studied by simultaneous thermal analysis. It was found that with an increase in neodymium content the weight loss increased from 0.75% to 3.16% for x =0.1 and...

Elimination of the chemical and microbiological pollutants in the modernized watewater treatment plant ''Wschód'' in Gdańsk.
PublicationW artykule przedstawiono wyniki 2 letnich, kompleksowych badań efektywności zanieczyszczeń chemicznych, mikrobiologicznych i parazytologicznych w zmodernizowanej oczyszczalni ścieków ''Wschód'' w Gdańsku. Oceniono wpływ funkcjonowania układu generowania lotnych kwasów tłuszczowych na skuteczność usuwania związków biogennych oraz jego oddziaływanie na eliminację zanieczyszczeń biologicznych z oczyszczonych ścieków

Balance of pesticides mass in gas, liquid and solid phase after their chemical degradation.
PublicationOpisano metodę usuwania pestycydów z wody przy zastosowaniu fotodegradacji (UV) i katalizatora (TiO2). Efektywność procesu usuwania pestycydów była kontrolowana przy zastosowaniu chromatografu gazowego z detektorem wychwytu elektronów. Oznaczano zawartość pestycydów w wodzie, a także zaadsorbowanych na powierzchni stałej, oraz w fazie gazowej. Największa zawartość pestycydów znajdowała się na fazie stałej, następnie w cieczy i...
