Goals: The project aims to develop new green lignin-activated carbon composites derived from plant waste (rice husks) and modified with Ti3C2Tx MXene to efficiently remove common heavy metal ions from aqueous media.
Tasks: To achieve the goals of the project, it will be divided into 7 work packages
Short abstract about project: More than 100 lakes, rivers and reservoirs in Kazakhstan are polluted with toxic heavy metals much higher than the MPC standards, which directly or through transmission through the food chain negatively affects human health and the
environment. Various sorbents and technologies could be used to purify such waters. Rice husk (RH), a waste of plant origin, is an available precursor for the production of various adsorbents, which otherwise would be burnt with the consequent emission of CO2 and detrimental effect on Kazakh air quality. The project aims to develop composites obtained from rice husk and hence give value to what could be a source of
pollution. Polymers, activated carbons and MXenes have separately proven themselves to be effective adsorbents, and our main hypothesis is that combining these sorbents into a composite material will synergistically increase their effectiveness through different mechanisms for binding heavy metal ions from water.
Tasks: To achieve the goals of the project, it will be divided into 7 work packages
- Optimization of methods for obtaining lignin from rice husk.
- Synthesis of cryogels and aerogels from lignin and other reagents.
- Obtaining activated carbons from rice husks with specified parameters of porosity and specific surface area.
- Synthesis of composites from the obtained materials
- Study of the chemistry, morphological and physicochemical properties of the obtained adsorbents and composites.
- Investigation of the effectiveness of composites in the removal of heavy metals, metalloids and their existing oxyanions in environmentally relevant conditions under static and dynamic conditions.
- Study of composites after removal of heavy metal/ metalloid ions, study of the removal mechanisms, as well as the effect of the multicomponent composition on the elimination capacity.
