چکیده

PREPARATION OF IRON/CARBON MATERIAL FROM BIODIESEL WASTE FOR APPLICATION IN THE REMOVAL ORGANIC CONTAMINANTS. In this work, iron/carbon-based catalysts obtained from biodiesel residues, glycerin, were prepared.The composites prepared by thermal carbonization of the glycerin polymer, in presence iron salt. The materials characterized adsorption/desorption N2, scanning electron microscopy (SEM), X-ray diffraction (XRD), Raman spectroscopy and thermogravimetric analysis. XRD analysis have shown hematite magnetite. methylene blue (MB) adsorption oxidation tests reached 99% color removal hydrogen peroxide. steadystate spectra confirmed MB reduction fluorescence intensity. Besides, it has high stability, with no active phase leaching, proving a heterogeneous process.

In many applications, the dearth of information to a proper training and use of supervised Machine Learning methods is a persistent problem. This fact led to the development of the semi-supervised learning paradigm. This paradigm can be understood as a combination of concepts of unsupervised and supervised paradigms. The way how the learning is conducted allows to organize the semi-supervised m...
