The aim of this project consists of the development of novel and low-cost multi-functional material based on MO-biochar functionalized nanocomposite hydrogel (Fe3O4) for a wide range of applications: treatment of marginal water for mitigation of hydro-climatic extreme events, especially droughts in the catchment of different sources of irrigation water, water saving, and soil fertilization.
The specific objectives (SOs) of the research are listed below:
SO1. Preparation and characterization of cost-effective new superabsorbent materials based on biocompatible polymers and biochar functionalized with MO (WP1);
SO2. Evaluation of the removal efficiency of organic pollutants from polluted water using the superabsorbent material. Assessment of the recycling efficiency of and reusing the superabsorbent material (WP2);
SO3. Testing the attenuation of ARGs and ARB by the new adsorbent from greywater effluents using established molecular methods (qPCR and sequencing) (WP2);
SO4. Assessment of the impact of the superabsorbent material on the physical, chemical, and biological properties of soil and its effects on bean crops (growth development, yield, and crop) under current and predicted climate change scenarios (WP4).
