Nanomaterials For Analytical Uses and Their Applications to Environmental Analysis

Abstract

- The thesis content can be portrayed briefly as five chapters:  Chapter (I): General introduction: - This chapter contains a general introduction regarding the work done and includes two parts: • Part (I): It illustrates the principles and main components of potentiometric sensors and an overview of conventional ion-selective electrodes (ISEs) with their limitations. The transformation from conventional ISEs contain liquid contacts (typically referred to as inner filling solutions) to solid-contact ISE. The difficulties facing solid-contact ISE and the types of materials used to act as ion-to-electron transducers with their mechanism of response. Finally, Challenges facing potentiometric solid-contact ion-selective electrodes (SC-ISEs). • Part (II): Magnetic Nanoparticles (MNPs) have attracted a great interest due to their superior magnetic properties, high adsorption capacity, surface area-to-volume ratio, simple chemical composition, and wide applications in a number of fields including wastewater treatments that greatly affects the community health and economic well-being. In this part, I will give an overview of magnetic nanoparticles, especially metal ferrites (MFe2O4), their types, methods of preparation, and modification for the removal of hazardous environmental pollutants.
