Adsorptive desulfurization and denitrogenation of model fuel by mesoporous adsorbents (MSU-S and CoO-MSU-S)

Adsorption of heterocyclic sulfur- and nitrogen-containing compounds by mesostructure adsorbent (MSU-S) and its modified form with cobalt oxide is studied using model fuel. The results of characteristic tests (XRD, N₂ adsorption–desorption, FTIR, and SEM) indicate that CoO impregnation causes a negative impact on mesoporous structure, crystalline phase, and particle shape along with a positive effect on surface ion exchange. CoO modification increased the adsorption loadings of DBT and BT to about 33.6% and 45.7%, respectively. For nitrogen compounds adsorption with the model fuel, adsorption loadings of quinoline and carbazole increase by 6.7% and 8.6%, respectively. Data fitting for carbazole, DBT, and BT is achieved better by the Langmuir model than the Freundlich model, and the data of quinoline fitted very well to the Freundlich model for CoO-MSU-S.     

Development of lateral flow immunoassay for rapid control and quantification of the presence of the colorant Sudan I in spices and seafood

The lateral flow immunoassay for colorant Sudan I detection was developed using the monoclonal antibody to Sudan I conjugated with gold nanoparticles. Conditions of the assay were optimized for both qualitative control and quantification of Sudan I in food matrixes with minimal dilution of the extracting media (final content of methanol – 50%). In the case of photometric registration, the limit of Sudan I detection in extracts was 2.5 ng/mL (which corresponds to 10 μg/kg of food and spices), and the working range of determined concentrations was 13–240 ng/mL. The average error of measurements varied from 5.5 to 16.9%. The visual limit of detection, which is the minimum concentration causing absence of visible coloration at the test zone, was 1 μg/mL. The assay efficiency was confirmed by its application to determine Sudan I content in highly colored spices (turmeric, curry) and seafood (caviar, mussels, fish). Thus, the developed assay is suitable as a rapid, inexpensive tool for revealing Sudan I quantification by mobile laboratories and in out-of-laboratory conditions.
