Abstract
Journal of the Geological Society of Sri Lanka is a peer-reviewed and open access journal published by the Geological Society of Sri Lanka. It aims to publish the most topical and highest quality papers, summarizing the results of recent research across all sub-disciplines of the Earth Science. Papers are frequently interdisciplinary covering both pure and applied fields of Geology. Contributions often refer to local, regional and/or international studies and emphasize the development of the understanding of fundamental geological processes.
Highlights
In recent years, an increasing number of applications and products containing or using nanomaterials have become available
We focused to develop a low-cost, industrially viable method to produce magnetite nanoparticles (MNP) from commonly available laterite in Sri Lanka
Hydrochloric acid (38% assay and 99% purity), nitric acid (69% purity), sodium hydroxide (99% purity), ethylene glycol were used for the extraction of iron from laterite and for the synthesis of MNPs
Summary
An increasing number of applications and products containing or using nanomaterials have become available. Nanotechnologies include the development and production of nano-sized particles, fibers and coatings, as a group referred to as nanomaterials. They are having particles or constituents of nanoscale dimensions (1-100 nm) and are intentionally manufactured materials. When the particles are at the nanoscale, compared to the macro- or microscale particles, the properties of the material change in terms of physically, chemically and mechanically. There is an everincreasing demand for low-cost nanomaterials produced from less expensive raw materials since the conventional production cost of these nanomaterials is immensely high
