Removal of 2,4-D herbicide from aqueous solution by aminosilane-grafted mesoporous carbons

2,4-Dichlorophenoxyacetic acid (2,4-D) is the most commonly used herbicide in plant protection products. 2,4-D is poorly biodegradable and it is often found in aquatic environment. The development of an effective way to reduce the amount of this toxic contaminant from aqueous solution became an urgent issue. Therefore, in this study series of aminosilane-grafted mesoporous...

Physicochemical characterization of ordered mesoporous carbons functionalized by wet oxidation

Ordered mesoporous carbon obtained by the soft template method was subjected to oxidation with the use of ammonium persulfate or nitric acid. The material was modified in different conditions in order to generate on its surface oxygen functional groups. Functionalization of carbon with nitric acid or ammonium persulfate at low temperatures caused a reduction in its surface area...

Sorptive properties of aluminium ions containing mesoporous silica towards l-histidine

The applicability of aluminium-containing mesoporous materials as carriers for l-histidine has been evaluated for the first time. The modified mesoporous silica such as SBA-15 and SBA-16 were synthesised by hydrothermal method and characterised by low-temperature nitrogen sorption, transmission and scanning microscopy, X-ray and laser diffraction methods. The results of these...

Complex of Rutin with β-Cyclodextrin as Potential Delivery System

This study aimed to obtain and characterize an RU-β-CD complex in the context of investigating the possibility of changes in the solubility, stability, antioxidative and microbiological activity as well as permeability of complexated rutin as against its free form. The formation of the RU-β-CD complex via a co-grinding technique was confirmed by using DSC, SEM, FT-IR and Raman...
