Solid-phase extraction of polar benzotriazoles as environmental pollutants
Ida Kraševec, Helena Prosen
Pregledni znanstveni članek
Oznake: benzotriazoli;ekstrakcija na trdno fazo;okoljski vzorci;benzotrazoles;solid-phase extraction;environmental samples;
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 ...

Determination of cellulose degree of polymerization in historical papers with high lignin content
Jasna Malešič, Ida Kraševec, Irena Kralj Cigić
Izvirni znanstveni članek
Oznake: weight average molecular mass;average degree of polymerization;cellulose;size-exclusion chromatography;lignin;viscometry;historical papers;chlorite/acetic acid;
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 ...

Določanje hlapnih organskih spojin v laboratorijih in pisarnah
Rok Kranjc, Irena Kralj Cigić, Ida Kraševec
Diplomsko delo
Oznake: hlapne organske spojine;pasivni vzorčevalniki;detektor celokupnih HOS;kakovost zraka;diplomske naloge;
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 ...

Non-destructive detection of pentachlorophenol residues in historical wooden objects
Ida Kraševec, Nataša Nemeček, Maja Lozar Štamcar, Irena Kralj Cigić, Helena Prosen
Izvirni znanstveni članek
Oznake: pentaklorofenol;les;muzejske zbirke;mikroekstrakcija na trdno fazo;vzorčenje plinaste faze nad vzorcem;kontaktna SPME;GC-MS;neporušna metoda;pentachlorophenol;wood;museum collections;solid-phase microextraction;headspace;contact SPME;non-destructive method;
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 ...

Removal of benzotriazole derivatives by biochar
Sabolč Pap, Olivera Paunovic, Helena Prosen, Ida Kraševec, Polonca Trebše, Lydia Niemi, Mark Taggart, Maja Turk Sekulić
Izvirni znanstveni članek
Oznake: adsorption;characterisation;wastewater;emerging pollutant;desorption;modelling;
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 ...

Evaluation and modelling of the environmental performance of archival boxes
Morana Novak, Josep Grau-Bové, Caroline De Stefani, Caroline Checkley-Scott, Ida Kraševec, Irena Kralj Cigić, Abdelrazek Elnaggar
Izvirni znanstveni članek
Oznake: arhivske škatle;mikrookolja;relativna vlažnost;sorpcija vlage;prenos vlage;stopnje prenosa zraka;stopnje prenosa vodne pare;archival boxes;microenvironments;relative humidity;moisture sorption;moisture transfer;air exchange rates;water vapour transmission rates;
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 ...
