Researchers from the University of Granada (UGR), and from the Center for Electrochemical Research and Technological Development (Centro de Investigaci\u00f3n y Desarrollo Tecnol\u00f3gico en Electroqu\u00edmica, CIDETEQ) and the Center of Engineering and Industrial Development (Centro de Ingenier\u00eda y Desarrollo Industrial, CIDESI), both in Mexico, have developed a process that allows to clean waters containing heavy metals and organic compounds considered pollutants, using a new adsorbent material made from the peels of fruits such as oranges and grapefruits.<\/p>\n
Said peels are residues which pose a problem for the food industry, given that they take up a great volume and aren’t very useful nowadays. 38.2 million tons of said fruit peels are estimated to be produced worldwide each year in the food industry.<\/p>\n
The research, in which the UGR participates, has served for designing a new process by which, thanks to an Instant Controlled Pressure Drop treatment, it is possible to modify the structure of said residues, giving them adsorbent properties such as a greater porosity and surface area.<\/p>\n
Researcher Luis Alberto Romero Cano, from the Carbon Materials Research Team (Grupo de Investigaci\u00f3n en Materiales de Carb\u00f3n) at the Faculty of Science, UGR, explains that, by a subsequent chemical treatment, they “have managed to add functional groups to the material, thus making it selective in order to remove metals and organic pollutants present in water”.<\/p>\n
A subsequent research carried out by the authors of this paper has showed that it is possible to pack those new materials in fixed bed columns, in a way similar to a filter by which wastewater runs on a constant flux process, like the usual wastewater treatments. This laboratory-scale study has allowed to obtain parameters to design a large-scale use of said materials.<\/p>\n
“The results show a great potential for the use of said materials as adsorbents capable of competing with commercial activated carbon for the adsorption and recovery of metals present in wastewater, in a way that it could be possible to carry out sustainable processes in which products with a great commercial value could be obtained from food industry residues”, Romero Cano says.<\/p>\n","protected":false},"excerpt":{"rendered":"
