Polar benzotriazoles are corrosion inhibitors with widespread use; they are environmentally characterized as emerging pollutants in the water system, where they are present in low concentrations. Various extraction methods have been used for their separation from various matrices, ranging from class ...

Per- in polifluoroalkilne snovi so za človeka zaradi svojih izjemnih fizikalno-kemijskih lastnosti zelo uporabne. Žal pa so povezane tudi s slabimi vplivi na zdravje človeka in okolje. Zaradi svoje stabilnosti in zmožnosti prehajanja iz vode in tal v ozračje ter nazaj, se v okolju kopičijo in predst ...

Determination of cellulose degree of polymerization (DP) is one of the most commonly used methods in paper degradation studies, performed either by a standardized method using viscometry (as average degree of polymerization (DP$_v$)) or size-exclusion chromatography (SEC) (as weight average molecula ...

Hlapne organske spojine (HOS) so lahko naravnega ali antropogenega izvora in lahko vplivajo na zdravje ljudi, kakovost zraka in na materiale ter na predmete, ki se nahajajo v prostorih s povišano koncentracijo HOS. V svoji diplomski nalogi sem v izbranih prostorih fakultete meril celokupne koncentra ...

V diplomskem delu sem optimizirala metodo velikostno izključitvene kromatografije (SEC) za določanje proteina fibroina, ki je glavna komponenta svile. Analiza s SEC metodo omogoča vpogled v porazdelitev molskih mas fibroina, kar je pomembno za karakterizacijo svile, ki je pomembna tako za številne s ...

Enclosure materials can have a variety of properties that moderate relative humidity (RH) in relation to external RH fluctuations. In this study of different constructions and board types we developed a simple empirical model to predict the relative humidity damping capacity via a Humidity Attenuati ...

Wood is a natural polymeric material that is an important constituent of many heritage collections. Because of its susceptibility to biodegradation, it is often chemically treated with substances that can be harmful to human health. One of the most widely used wood preservatives was pentachloropheno ...

The acidity of historic paper, a property crucial for its preservation, is thought to mainly depend on the type of sizing. However, this research shows that during its degradation, paper acidity increases mainly due to the formation of non-volatile carboxylic acids, which accelerate acid-catalysed h ...

Benzotriazole and its derivatives (BTAs) are commonly present in wastewater due to their extensive use in industrial processes, yet their removal is still unexplored. Here, we test the removal of these pollutants using two functionalised biochars, synthesised from wild plum (WpOH) and apricot (AsPhA ...

Archival boxes are used as a preventive measure to control the microenvironment in museums and archives storages. However, their efficiency in protecting valuable artefacts from fluctuations in relative humidity (RH) is not yet fully understood. In this study, the environmental performance of differ ...
