Oznaczanie stężeń jonów fluorkowych w próbkach wody pitnej z terenu miasta Malborka = Determination of fluoride ions in drinking water samples collected from the area of the town of Malbork
PublikacjaW pracy przedstawiono badania próbek wody pitnej z terenu miasta Malborka. Próbki wody pobierano sześciokrotnie (w miesięcznych odstępach - październik 2008, listopad 2008, grudzień 2008, styczeń 2009, luty 2009 oraz marzec 2009) w siedmiu punktach leżących w głównych dzielnicach miasta Malborka. Pobrane próbki podano analizie w celu oznaczenia następujących parametrów: zawartość anionów: F-, Cl-, Br-, 2NO , 3NO , 34 PO , 24 SO...

Poly(hydroxybutyrate-co-hydroxyvalerate) as a biodegradable binder in a negative electrode material for lithium-ion batteries
PublikacjaIn this work, graphite-based negative electrode for lithium-ion battery consisting a novel and biodegradable binder poly(hydroxybutyrate-co-hydroxyvalerate) (PHBV) is compared with standard graphite electrode with polyvinylidene fluoride (PVDF) as a binder. The rate and cycling performance of lithium ion insertion/extraction of electrodes with PHBV in a half-cell configuration are evaluated. Moreover, on the basis of the electrochemical...

Results of the effect of mixtures of ketoprofen with three anions on the germination of Sorghum bicolor (sorghum) seeds
Dane BadawczeThe research data includes an attempt to verify whether the addition of anions (bromide, chloride and fluoride) at levels found in the environment would affect the toxicity of pharmaceuticals to Sorghum Bicolor grain. Ion concentrations were selected based on studies of water samples collected in water bodies receiving wastewater from wastewater treatment...

Groundwater Quality in the Gdansk Aquifer System
PublikacjaThe Gdańsk hydrogeological system consists of three main aquifers: Cretaceous, Paleogene-Neogene and Pleistocene. Chemical composition of groundwater varies between water-bearing beds, although water from Pleistocene and Paleogene-Neogene aquifers shows much similarities. The dominant hydrochemical groundwater types is HCO3-Ca. This type is characteristic for Pleistocene deposits in the Kashubian Lake District where natural chemical...
