Abstract

This study investigated for the first time the degradation of phenol, chlorophenol, fluorophenol and bisphenol A (BPA) by the novel iron phthalocyanine/spongin hybrid material under various process conditions: hydrogen peroxide and UV irradiation. The heterogeneous catalyst, iron phthalocyanine/spongin (SFe), was produced by an adsorption process. The product obtained was investigated by a variety of spectroscopic techniques - X-ray photoelectron spectroscopy (XPS), energy-dispersive X-ray spectroscopy (EDS), Fourier transform infrared spectroscopy (FTIR) and carbon-13 nuclear magnetic resonance (13C NMR) - as well as elemental and thermal analysis. The study confirmed the stable immobilization of the dye on the biopolymer. The results demonstrate that the degradation of phenols and BPA followed pseudo-second-order kinetics under different experimental conditions. The synergy of SFe, H2O2 and UV was found to produce a significant increase in the removal efficiency and resulted in complete removal of contaminants in a short time of 1?h. The reaction products were identified by high-performance liquid chromatography/mass spectrometry (HPLC-MS) and possible degradation pathways were proposed, featuring a series of steps including cleavage of CC bonds and oxidation.

Iron

26 Fe 55.845000000 Iron

See more Iron products. Iron (atomic symbol: Fe, atomic number: 26) is a Block D, Group 8, Period 4 element with an atomic weight of 55.845. The number of electrons in each of Iron's shells is 2, 8, 14, 2 and its electron configuration is [Ar] 3d6 4s2. Iron Bohr ModelThe iron atom has a radius of 126 pm and a Van der Waals radius of 194 pm. Iron was discovered by humans before 5000 BC. In its elemental form, iron has a lustrous grayish metallic appearance. Iron is the fourth most common element in the Earth's crust and the most common element by mass forming the earth as a whole. Iron is rarely found as a free element, since it tends to oxidize easily; it is usually found in minerals such as magnetite, hematite, goethite, limonite, or siderite.Elemental Iron Though pure iron is typically soft, the addition of carbon creates the alloy known as steel, which is significantly stronger.

Nitrogen
