Fabrication of novel agrowaste (banana and potato peels)-based biochar/TiO2 nanocomposite for adsorption of Cr(VI), statistical optimization via RSM approach

In this research work, a simple, efficient, and eco-friendly procedure for the biosorption of Cr(VI) ions was studied. A detailed comparative study was performed to check the adsorption efficiency of agrowaste (banana and potato peels)-based adsorbents. Firstly, mixed biosorbent was washed, dried an...
