Zielsetzung und Themenschwerpunkte (Objectives and Key Themes)

This research aims to extract humic acid from sediments collected from Eniong River, Nigeria, using a green chemistry approach. The extracted humic acid is then characterized using UV-Vis and FTIR spectroscopy, and its surface properties are investigated.

• Extraction of humic acid from river sediments
• Characterization of humic acid using spectroscopic techniques
• Investigation of the surface properties of the extracted humic acid
• Potential applications of humic acid as an adsorbent
• The role of humic substances in the environment

Zusammenfassung der Kapitel (Chapter Summaries)

The introduction provides a historical overview of humic substances, their importance in soil and water environments, and the different mechanisms proposed for their formation. It discusses the different types of humic substances, including humic acid, fulvic acid, and humin, and highlights their chemical properties and structural characteristics.

The experimental section describes the study area, Eniong River, and outlines the methodology for extracting humic acid from the collected sediments. It details the characterization techniques employed, including UV-Vis and FTIR spectroscopy, and the investigation of the surface properties of the extracted humic acid.
