Badanie adsorpcji surfaktantu anionowego LAS na kłaczkach osadu czynnego
PublikacjaBadano adsorpcję surfaktantu anionowego LAS na osadzie czynnym pobranym z oczyszczalni ścieków w Swarzewie. Opracowano metodykę separacji i oznaczania surfaktntu w cieczy nadosadowei i w osadzie. Stwierdzono, że na osadzie adsorbuje się około 50-75% całej ilości surfaktantu, w roztworze pozostaje 6-12%, zaś straty wynikające z biodegradacji lub adsorpcji LAS na ściankach naczyń podczas procedury analitycznej stanowią od 25 do 32%.

Mass Spectrometric Identification of 13C-labeled Metabolites During anaerobic Propanoic Acid Oxidation
PublikacjaBiowaste digestion is a possibility to gain biogas as a renewable fuel source. However, the anaerobic food chain may be disrupted by, e.g., substrate overload or by inhibitors, leading to the accumulation of volatile fatty acids (VFAs), predominantly of propanoic acid (PA). VFA Accumulation may cause a rapid pH decrease, less biogas production, or even a total inhibition. To maintain high biogas productivity or to prevent a collapse...
