PHOTOCATALYTIC DEGRADATION OF ANIONIC AND CATIONIC DYES USING IRON-OXIDE NANOPARTICLES
ABSTRACT
The study determines the Photocatalytic Degradation of Anionic and Cationic Dyes using Iron-oxide Nanoparticles. In achieving this aim, the following specific objectives were laid out to identify the Photocatalytic Degradation of Anionic using Iron-oxide Nanoparticles, carry out a Spectroscopic Analysis of Iron-oxide Nanoparticles (Fe2O3-Nps), determine the Photocatalytic Degradation of Anionic and Cationic Dyes, and evaluate the Iron-oxide Nanoparticles from Photocatalytic Degradation of Cationic Dyes. The motivation of the study is that the effects of inhaled nanoparticles in the body causes lung inflammation and heart problems. The pulmonary injury and inflammation resulting from the inhalation of nanosize urban particulate matter appears to be due to the oxidative stress that these particles cause in the cells. Therefore the research work will provide vital information to eliminate the stated problem. Cationic dyes are dyes that can be dissociated into positively charged ions in aqueous solution. They can interact with the negative groups on the fiber molecules to form salts, which can be further firmly attached to the fibers, thereby staining the fibers. Iron oxide nanoparticles are iron oxide particles with diameters between about 1 and 100 nanometers. This study will be of immense benefit to researchers who intend to know more on this study and can also be used by non-researchers to build more on their research work. This study contributes to knowledge and could serve as a guide for other study.
CHAPTER ONE
1.0 Introduction
1.1 Background of Study
The dye decolourisation using biological system is a complex process requiring a suitable enzyme system in bioremediation of such effluents. Such dye rich effluents can be treated through metal oxide nanoparticle by the photocatalytic degradation process. Photocatalytic reactions are induced by the illumination of nano- sized semiconductors such as TiO2, ZnO, ZnS, WOγ and Fe2O3 in a suspension and they are most promising for the wastewater treatment (Dai et al., 2007) because of their high stability, low costs, high efficiency and no toxicity (Dipti et al., 2010). Among various semiconductors used in photocatalysts, iron oxide nanomaterials exhibit promising photocatalytic activities (Leland et al., 1987 and Bharathi et al., 2009). However, ‘combinational’ nanoparticle systems were used previously for the dye photocatalytic degradation activity. In the present study, we focused on the application of Fe2O3-Nps alone in the photocatalytic degradation activity of some selected Anionic and Cationic Dyes.
The environmental engineering applications of many metal oxide nanoparticles, especially iron oxide nanoparticles (Fe2O3- Nps) have been reported. Recently, metal nanoparticles and metal oxide nanoparticles are used as nano-adsorbents, nano-catalysts, nano-filtration and nano-biocides for remediation of water and wastewater pollutants. Among them, potential of iron nanoparticles was found suitable for environmental remediation. The nanoscale zero-valent iron has a large surface area to volume ratio, which enhances their reactivity especially in the environmental applications (Lin et al., 2009).
Nanotechnology is a tool of the recent decade to resolve many issues related to environment and health care. The nano-scale particles have numerous advantages and are widely explored for its new functionalities. The metal nanoparticles production is usually carried out using physical and chemical methods. An array of chemicals is required for the metal nanoparticles production, which is very reactive and toxic reducing agent. This brings about many deleterious effects during its application in health care and environmental engineering. In the meantime, many facile and reliable green technologies were adopted for the production of these nanoparticles. Among the green technologies, various organisms act as precursors to produce the stable and well- functionalised nanoparticles, which include bacteria, actinomycetes, fungi, yeast, viruses, plants and so on (Mandal et al., 2006 and Jebali et al., 2011). Plant- mediated nanoparticle synthesis is more reliable in terms of its monodispersed nature, stability and fast synthesis compared to other precursors (Iravani et al., 2011). Various part of plants can be used for the metal nanoparticle synthesis and the process is the simplest and most cost-effective (Kalaiarasi et al., 2010).
Therefore, in Nigeria where the research was carried out, the activities that was conducted is to know the Photocatalytic Degradation of Anionic and Cationic Dyes using Iron-oxide Nanoparticles.
