Optimizing 2-nitrophenol and chromium adsorption from water with aluminium oxide via response surface methodology

The study explored the efficacy of an innovative adsorbent crafted from carbon nanotubes and carbon nano fibbers integrated with aluminium oxide, in purging water solutions of both organic (2-Nitrophenol) and inorganic (Chromium III) contaminants. The study refined the aluminium impregnation method...
