Revelation of Fe(V)/Fe(IV) Involvement in the Fe(VI)-ABTS System: Kinetic Modeling and Product Analysis.

Environmental Science and Technology, 2021
To quantitatively probe iron intermediate species [Fe(V)/Fe(IV)] in Fe(VI) oxidation, this study systematically investigated the reaction kinetics of Fe(VI) oxidation of 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic)acid (ABTS) at different ratios of [

Chalcones and Bis-Chalcones Analogs as DPPH and ABTS Radical Scavengers

, 2020
A number of synthetic scaffolds, along with natural products, have been identified as potent antioxidants. The present study deals with the evaluation of varyingly substituted, medicinally distinct class of compounds “chalcones and bis-chalcones” for ...

MnO2 nanozyme induced the chromogenic reactions of ABTS and TMB to visual detection of Fe2+ and Pb2+ ions in water

International Journal of Environmental Analytical Chemistry, 2019
In this study, we used a simple and rapid colourimetric reaction for visual sensing of Fe2+ and Pb2+ ions in water by employing nano-MnO2 as a natural oxidase mimic to respectively catalyse ABTS and TMB in citrate-phosphate buffer solution (C-PBS) at 25 ...

ABT-Quickscan

2007
Nederland is al aardig volgebouwd. De bouwgrond is schaars en het overheidsbeleid is gericht op verdichting. Daarnaast wordt de functionele levensduur van gebouwen alsmaar korter, terwiji fundering en constructie nog jaren mee kunnen. Een gevoig is dat de Nederlandse bouwmarkt zich steeds meer richt op hergebruik en herbestemming van bestaande gebouwen.
