Effect of reducing agent on the removal of halogenated organic biocides Triclosan and bromoxynil from water

Abstract

Halogenated organic compounds are usually recalcitrant compounds and can enter the environment from production and application of chemical specialties. Examples of modern organic halogenated phenols tested in this study are Triclosan and Bromoxynil. Triclosan is commonly used as an antibacterial and fungicidal agent. Bromoxynil is used as an herbicide for deciduous trees. The aim of technological processes minimizing the impacts of the use of these compounds is to remove them from effluents - for example, by chemical transformation into easily biodegradable products. One possibility is the use of reductive dehalogenation using a suitable reducing agent. As the reducing agent, hydrogenation using noble metals or application of metallic alloys of electropositive metals with hydrogenation catalysts can be applied.
