Scholarcy highlights

  • The industrial development of certain industries such as pharmaceutical, chemical, petrochemical, and agrifood industries leads to the waste generation
  • Geomaterials used were prepared based on clay from western Algeria, activated carbon powder made from coconut purchased from Merck, Portland
  • GM3 has a specific surface area of 102.90 m2 g−1 and a pore volume Vp of 0.21 cm3 g−1, which are 63.82 m2 g−1 and 0.1 cm3 g−1 and S of 79.89 m2 g−1 and Vp of 0.12 cm3 g−1, respectively, for GM1 and GM2. It has been demonstrated in a previous study that the adsorption of pollutants on geomaterials is the contribution of mineral constituents, namely, clay, activated carbon, and cement
  • The purpose of the present study is, first, to develop composite materials called geomaterials. These materials were based on Algerian clay, activated carbon, cement, and PVA polymer, these materials were used in the retention of an organic pollutant such as paracetamol
  • The synthesized geomaterials were characterized by nitrogen adsorption and desorption, X-ray diffraction, and Scanning electron microscopy
  • The obtained results showed that: – The equilibrium is reached after relatively short contact times 180 min for GM1 and 120 min for GM2 and GM3. – From results, the most suitable geomaterial for paracetamol removal is GM3, due to its physicochemical properties
