Adsorbents from Schinopsis balansae: Optimisation of significant variables

▶ Schinopsis balansae is a good tannin feedstock for adsorbent production (detergent and dye removal in aqueous solutions). ▶ Best polymerization conditions: 75 °C, 0.07 g HCHO/g tannin. ▶ Plane non-porous surface, macroporosity. ▶ Langmuir adsorption of cetylmethylammonium bromide and methylene blue.
