Mobility and biodegradability of an imidazolium based ionic liquid in soil and soil amended with waste sewage sludge
PublicationSorption on solids and biodegradation are main phenomena that can mitigate the pollution of soil and water by ionic liquids (ILs). ILs sorbed on soil particles become immobilized (temporarily or permanently) which prevents them from spreading into deeper layers of soil or groundwater but which also makes them less bioavailable. In this study we attempt to examine if amendment of soil with waste sludge has a potential to mitigate...

Metodyka wykonywania pomiarów oraz ocena niepewności i błędów pomiaru
Publicationelem każdego ćwiczenia w laboratorium studenckim jest zmierzenie pewnych wielkości, a następnie ob- liczenie na podstawie tych wyników pomiarów wartości wielkości badanej. Rezulta- tem końcowym badań jest nie tylko otrzymany wynik liczbowy. Nie mniej ważne jest dokonanie oceny dokład- ności pomiaru oraz opraco- wanie wniosków końcowych. Warto zadać sobie pytanie: czy to, co zostało zmierzone, ma sens i co z tego wynika?...
