EN Zeolite matrices have been applied for embedment of sulfur radical chromophores inside the intra-crystalline cages. The thermal treatment of zeolites (200–800 graduate C) with sulfur radical precursors (oligosulfides, elemental sulfur and alkalis) led to colored products. Their coloration (yellow, g[...]

EN The concentration of chlorophylls and carotenoids with respect to communities of characteristic phytoplankton species and hydrological parameters, such as temperature, salinity and nutrients were analysed. Samples from the southern Baltic were taken during three periods: spring 1999, autumn 1999 and[...]

EN In this study, 12 taxa from the Chlorophyta, Phaeophyta and Rhodophyta were collected from different depths at Gemlik-Karacaali and Erdek-Ormanl?. A total of 175 specimens from these divisions were used to determine Total Protein (TP), Total Soluble Carbohydrate (TSCH) and Chlorophyll a (Chl a), Chl[...]

EN Two cruises were undertaken in the Pearl River Estuary in November 2011 and March 2012 to analyze the distribution of phytoplankton pigments and to define the relationships of pigment indices and functional community structure with environmental factors. Among 22 pigments, 17 were detected by high-p[...]

EN Changes in phytoplankton pigment concentrations in Case 2 waters (such as those of the Baltic Sea) were analysed in relation to the light intensity and its spectral distribution in the water. The analyses were based on sets of empirical measurements containing two types of data: chlorophyll and caro[...]

PL Celem pracy było przystosowanie spektrofotometrycznej metody różnicowej do oznaczania acylowanych barwników antocyjanowych purpurowej marchwi. Zaproponowano modyfikację klasycznej spektrofotometrycznej metody różnicowej wg Giusti i Wrolstad. Stwierdzono, że zastąpienie buforu o pH 4,5 buforem o pH 6[...]
EN The objective of this study was to adapt the pH-differential method to the quantitave measurement of acylated anthocyanins of purple carrots. A modification of classic Giusti and Wrolstad's spectrophotometrical method has been proposed. It was found that replacing pH 4,5 buffer solution with pH 6,0 [...]

EN Adsorption of C.I. Basic Blue 9 (Methylene Blue Hydrate) on the surface of TiO2-SiO2 oxide composite unmodified or functionalized with N-2-(aminoethyl)-3-amino propyltrimethoxsysilane was investigated. The organic dye was supported on inorganic TiO2-SiO2 oxide composite precipitated in the emulsion [...]

PL Konwencjonalnie przeprowadzane badania fitoplanktonu opierają się na badaniach mikroskopowych. W związku z tym wymagają wysokiej sprawności w rozpoznawaniu grup taksonomicznych, są bardzo czasochłonne i nie pozwalają na ocenę stanu fizjologicznego glonów. Istnieje wiele, dających różny poziom dokład[...]
EN Conventional efforts at identifying algal phylogenetic groups rely on microscopic evaluation, which requires a high level of taxonomic skill, may consume considerable time, and does not allow characterisation of the physiological status of the taxa. A number of chemical methods with various level of[...]

PL Przedstawiono nowe rozwiązanie mieszalnika rozdrabniającego. Dzięki zastosowaniu dwóch umieszczonych acentrycznie mieszadeł, możliwe jest obniżenie mocy stosowanych urządzeń oraz uzyskanie wąskiego rozkładu ziarnowego rozdrabnianego pigmentu.
EN This paper presents a new construction of a grinding mixer. The power reduction of applied devices and narrow size distribution of grinding pigment are make possible due to use of two eccentric agitators.

PL Artykuł przedstawia wyniki badań nad otrzymywaniem i właściwościami pimentów ceramicznych w układzie Y2O3-Al2O3-Cr2O3, wytworzonych za pomocą reakcji w stanie stałym. Jony chromu wykorzystano jako chromofory w badanych pigmentach. Pigmenty ostatecznie syntezowano przez 6 h w 1500oC. Wykorzystano je [...]
EN The paper presents the results of research on preparation and properties of ceramic pigments in the Y2O3-Al2O3-Cr2O3 system which were obtained by the solid state reaction. The chromium ions were used as chromophores in these pigments. The pigments were finally synthesized for 6h at 1500oC. They wer[...]

EN Existing statistical models of in vivo light absorption by phytoplankton (Wozniak & Ostrowska 1990, Bricaud et al. 1995, 1998) describe the dependence of the phytoplankton specific spectral absorption coefficient a*pl() on the chlorophyll a concentration Ca in seawater. However, the models do not ta[...]

EN Eutrophication in two different coastal areas – the Gulf of Gdańsk (southern Baltic) and the Oslofjord/Drammensfjord (Norway) – both subject to human pressure and with restricted water exchange with adjacent seas, was investigated and compared. Sediment cores (up to 20 cm long) were collected at 12 [...]

EN We examine the narrowband shortwave minima (NSM) of multispectral reflectance as indication of mesoscale algal blooms. They are frequent in the Brazil-Malvinas confluence zone (BMCZ) where our testing site (TS) belongs. Its MODIS A images of December 2008 and 2014 were the source of initial data. Cl[...]

EN The distributions of chlorin components as well as chlorophylls c and β-carotene in postglacial sediments (down to ca 5 m depth), collected from the Gotland Deep in July 1997, have been determined. The major pigments were similar to those identified in recent (0–10 cm) sediment extracts of the [...]
