Comparative study of glyphosate removal on goethite and magnetite: Adsorption and photo-degradation

Oxidative effects of glyphosate on the lipophobic intracellular environment in the microalgae

“…This decrease was also detected after treatment with RUP at the studied concentrations. This unexpected response could be due to different possible effects of the herbicide: (a) GLY that could be degraded by processes, such as metal oxides/UV, Fenton/UV, Fenton-like/UV, ozonation, chlorination (Yang et al, 2018) was described to split into PO43-and sarcosine by the chemisorption of H 2 O and • OH in the existence of Fe oxides (Jaisi et al, 2016). For the sarcosine path, it can react with • OH and O 2 − to form glycine and formaldehyde directly.…”

Eco‐Friendly Nanoplatforms for Crop Quality Control, Protection, and Nutrition

“…[35,44] Recent reports indicate that glyphosate can accumulate in the soil for a long time due to the high affinity between phosphonate groups of glyphosate and iron oxides in the soil. [45] Therefore, it is of great significance to pay attention to the fate and toxicity of pesticides. Currently, a majority of the reported methods for the detection of pesticides are based on chromatography and capillary electrophoresis, exhibiting the advantages of high sensitivity and strong stability.…”

Treatment technologies and degradation pathways of glyphosate: A critical review

“…Chen and Liu (2007) found that the photodegradation efficiency of glyphosate increased with the increase of illumination time. Yang et al (2018) reported that with the increase of pH from 3 to 9, the photo-degradation of glyphosate in goethite/UV and magnetite/UV systems both decreased, indicating that an acidic condition is favourable for glyphosate photo-degradation. TiO 2 is a heterogeneous photocatalyst commonly used for glyphosate removal because of its stability, non-toxicity, and low cost.…”

“…The glyphosate photo-degradation is often related to both AMPA and sarcosine pathways. However, only sarcosine pathway for photodegradation is presented by Yang et al (2018). This is because the formation of Fe-O-P bond in the presence of iron oxide would change the electron density distribution around the phosphorus centre of glyphosate, and potentially induce the C-P bond more assailable to reactive oxygen species generated in goethite and magnetite suspension under UV irradiation.…”
