Equilibrium and kinetic mechanisms of woody biochar on aqueous glyphosate removal

“…Similarly, 1.26e1.48 mg L À1 concentration range of glyphosate was reported in natural waters of Brazil (Tzaskos et al, 2012). Although there is no specific guideline value for glyphosate, the European Union limits 0.1 mg L À1 for any herbicide in drinking water (Hu et al, 2011). While glyphosate is generally believed to be an environmentally safe herbicide due to microbial degradation and short half-life, recently its biosafety is questioned (Hagner et al, 2013).…”

“…Depending on soil structure and environmental conditions such as rainfall, glyphosate is prone to leaching and contaminating groundwater thereafter (Borggaard and Gimsing, 2008). Glyphosate is responsible for cardiac and respiratory problems, allergic reactions and many other acute toxic effects (Hu et al, 2011). Glyphosate is considered as an endocrine disruptor in human cell lines (Richard et al, 2005).…”

Current status of pesticides application and their residue in the water environment in Ireland

“…Al holds great promise of adsorption affinity with phosphorus; which is the basic monomer of most pesticides. Hu et al [31] have advocated the reuse of Al-WTR as pesticide pre-treatment to prevent their entry to water bodies in various runoffs.…”

“…Results show that the pesticides can be successfully removed mainly by the integrated adsorption and the enhanced superior photocatalyst. Hu et al [31] have studied pesticide removal by using water treatment residual (WTR) as a low cost-effective approach. WTR refers to the by-product generated inevitably from the production of drinking water in water treatment plants.…”

An activated carbon fiber cathode for the degradation of glyphosate in aqueous solutions by the Electro-Fenton mode: Optimal operational conditions and the deposition of iron on cathode on electrode reusability

“…Several conventional methods such as adsorption (Hu et al, 2011;Ren et al, 2014), membrane filtration (Speth, 1993), biological and chemical treatments (Jardim et al, 1997), have been used to treat glyphosate containing wastewater. The effectiveness of the above methods is varying.…”
