A method was developed for the simultaneous extraction of herbicides such as 2,4 D, MCPA, ametryn, chlorothalonil, and bromacil in water vegetable samples by emulsification liquid-liquid microextraction with fatty acids based hydrophobic deep eutectic solvents (DES). The DES were synthesised mixing several ratios that functioned both hydrogen bond acceptor (HBA) donor (HBD). Using solvent, vita...

When spinach thylakoids were subjected to moderate heat stress (40 degrees C for 30 min), oxygen evolution was inhibited, and cleavage of the reaction center-binding protein D1 of photosystem II took place, producing 23-kDa N-terminal fragments. The D1 cleavage was greatly facilitated by the addition of 0.15 mM ZnCl2 and 1 mM ATP and was completely inhibited by 1 mM EDTA, indicating the partici...

The catalytic effect of copper in Devarda’s Al-Cu-Zn alloy (Dev. alloy) and sole metallic copper, salts oxides the coaction NaBH4 within hydrodehalogenation (HDH) polybrominated phenols, such as herbicide Bromoxynil alkaline aqueous solution has been investigated. Namely, hydrodebromination (HDB) activity Dev. alloy/NaOH system compared to heterogeneous Cu-based catalysts using a reductant. Dif...
