saspro_logo

The project is financed from the SASPRO Programme – a programme of the Slovak Academy of Sciences dedicated for experienced scientists from abroad who are interested in working in the organisations of the Slovak Academy of Sciences. The project is funded by  the  People Programme (Marie Curie Actions) of European Union’s Seventh Framework Programme under REA grant agreement No. 609427 and by co-funding of Slovak Academy of Sciences.

 

Duration of the project:

01.03.2016 – 31.12.2018

About the project:

The purpose of the BISILMAG project is to develop bi(or multi)functional silica and magnetically removable adsorbents for water purification and remediation securing removal of chemical pollutants both organic and inorganic nature. SASPRO unites the efforts of the scientists and their expertise in two adjacent fields – synthesis and functionalization of mesoporous silica and silica-based adsorbents from Ukraine and advanced experience in physicochemical characterization of surface binding with valuable experience of their implementation in water purification from the Slovak side. Our specific aims: 1)Creation of silica microsheres with well defined composition for selective uptake of metal cations. 2)Сombination the properties of magnetite (easy removal from the reaction medium, recovery) with the assets of functionalized polysiloxane (specific groups, large specific surface area) and contribute to the selective removal of contaminating cations and organic molecules simultaneously. 3) Synthesis of nanocomposite multi-functional microparticles, testing them on wastewater samples modeling complex water systems. The goals will be achieved through coordinated research uniting the efforts of specialists in materials synthesis, characterization and application. In addition these materials are promising for applications in chromatography, drug delivery, creation of chemo- and biosensors, etc.

Objectives of the project:

The objectives of BISILMAG project is to create sorbents with binary functionality (functionctional groups of different nature), high sorption capacity (available groups of 2-3 mmol/g), good kinetic characteristics (mesoporous structure of the functional layer), easy retrievable from the reaction solution (magnetic) and with ability of rapid regeneration. To meet the sustainable ecological and economic requirements, our goal is geared towards the realization of the development of advanced adsorptive polysiloxane functionalized magnetic nanoparticles to remove heavy metal ions and organic dyes from water resources. With the development of new functionalized magnetic and silica nanoparticles it would be possible to separate a large part of the relevant heavy metals and dyes from urban wastewater treatment plants and industrial wastewater.
The originality of project lies in the use of organic-inorganic hybrid nanoparticles as elementary building units for the formation of new sorbent materials.
