Removal of Organophosphonate Herbicide: Adsorption onto Nanosilica
Glyphosate (IUPAC name: N-(phosphonomethyl)glycine) is a globally used phosphorous herbicide. Efficient technologies are currently unavailable for glyphosate removal. In this study, nanosilica functionalized with aminopropyl groups was synthesized and studied for glyphosate removal by adsorption. Th...

| description | Glyphosate (IUPAC name: N-(phosphonomethyl)glycine) is a globally used phosphorous herbicide. Efficient technologies are currently unavailable for glyphosate removal. In this study, nanosilica functionalized with aminopropyl groups was synthesized and studied for glyphosate removal by adsorption. The material was characterized by carrying out SEM, TG, FTIR, BET surface area and pore size distribution measurements. The results showed that the nanosilica was better suited for glyphosate adsorption following the Henry isotherm model, with the reaction being spontaneous and feasible. The performance (quantitative adsorption and complete nanosilica recovery) is worthy of note, considering that the sorbent can be regenerated and reused for at least five cycles. |
