“…The main component of numerous commercial formulations of herbicides is glyphosate (N-(phosphonomethyl) glycine), an organophosphorus chemical [185,190]. The main issue with glyphosate use is wastewater intrusion into streams and aquifers [185,191]. The ocean, fauna, flora, and ecological matrices (water and soil) are all in danger due to glyphosate contamination, which is a cumulative and continuous deterioration [185,191].…”

Water organic pollution has become a major issue. A large number of people suffer from the decline in water quality. In addition, polluted water can lead to health problems or excessive deaths. In this regard, an increasingly important method for efficient water treatment is electrocoagulation (EC), the technology that encompasses a small equipment size combined with a simple operation compared to other water treatment methods. The importance of EC is especially accentuated by the recent decarbonization efforts due to the increasing availability of renewable electricity systems. This review provides an overview of the most recent developments in EC technology as it pertains to wastewater treatment. The EC is preferred for organic wastewater treatment over other traditional treatment methods due to its easy setup and low material costs. Moreover, the EC is very powerful in destabilizing organic impurities by charge neutralization and then coagulating to form flocs. In addition, EC has shown high efficiency not only in removing various organic pollutants but also in emerging persistent contaminants, such as microplastics. For these reasons, the EC mechanisms and related functional modalities are reviewed, as well as extensive details are provided on the diversity of the removed contaminants. Overall, this review provides significant new knowledge of interest for environmental chemical researchers in particular and engineers in general on the details of the EC technology for wastewater treatment and water purification.

“…NU-1000, UiO-66, UiO-67, MIL-125, and MIL-101 have been shown as effective materials for GP adsorption. 58,[67][68][69] In contrast, studies involving MOFs for photodegradation of GP are lacking. 70 We therefore sought to utilize MOFs for combining rapid GP adsorption with selective photodegradation to benign products.…”

The impact of metals within a family of isostructural metal-organic frameworks (MOFs) on the adsorption and photodegradation of the herbicide glyphosate (GP) is presented in this study. Four MOFs, namely Sc-TBAPy, Al-TBAPy, Y-TBAPy, and Fe-TBAPy (TBAPy: 1,3,6,8-tetrakis(p-benzoic acid)pyrene), were characterized and evaluated for their ability to remediate GP from water. Among these materials, Sc-TBAPy demonstrates superior performance in both the adsorption and degradation of GP. Upon light irradiation for 5 min, Sc-TBAPy completely degrades 100% of GP in a 1.5 mM solution. Femtosecond transient absorption spectroscopy reveals that Sc-TBAPy exhibits enhanced charge transfer character compared to the other MOFs, as well as suppressed formation of emissive excimers that could impede photocatalysis. This finding was further supported by hydrogen evolution half-reaction (HER) experiments, which demonstrated Sc-TBAPy’s superior catalytic activity for water splitting. In addition to its faster adsorption and more efficient photodegradation of GP, Sc-TBAPy also exhibits selective oxidation of GP, avoiding the formation of toxic aminomethylphosphonic acid observed with the other M3+-TBAPy MOFs. To investigate the selectivity observed with Sc-TBAPy, electron spin resonance, depleted oxygen conditions, and solvent exchange with D2O were employed to elucidate the role of different reactive oxygen species on GP photodegradation. The findings indicate that singlet oxygen (1O2) plays a critical role in the selective photodegradation pathway achieved by Sc-TBAPy. Introduction

“…Along with their broad tunability, their large surface areas and abundant active sites make MOFs theoretically superior to traditional adsorbents and photocatalysts for GP removal. To date, research involving MOFs for GP remediation has focused primarily on adsorption 58,[67][68][69] , with few studies involving MOFs for photodegradation of GP 70 . NU-1000, UiO-66, UiO-67, MIL-125, and MIL-101 have been shown as effective MOFs for GP adsorption, with NU-1000 exhibiting exceptional adsorption perfomance 58,[67][68][69] .…”
