Water Decontamination with Magnetic Particles by Adsorption and Chemical Degradation. Influence of the Manufacturing Parameters

Abstract

[EN]Many di erent processes for manufacturing of magnetic particles are present in scientific literature. However, the large majority are not able to be applied to large-scale real operations. In this study, we present an experiment undertaken to determine advisable values and options for the main variables and factors for the application of the reverse co-precipitation method to produce magnetic particles for real environmental applications. In such, we have tried a conjugation of values/factors that has led to 12 main experiments and production of 12 di erent particles. After an initial study concerning their main characteristics, these 12 di erent particles were applied for the sorption removal of COD from real wastewater samples (e ciencies between 70% and 81%) and degradation of Methylene blue by Fenton reaction (degradation e ciencies up to 100%). The main conclusion from this work is that the best set of values depends on the target environmental application, and this set of values were determined for the two applications studied.
