Research Activities:


Dr Egiebor has conducted research on a broad range of environmental engineering and science topical areas of relevance to the energy, chemical, and resource industries, as well as to urban and rural municipalities for more than 2 decades. Our current and past research and teaching areas of interests and emphasis are as follows:

   1. Water and wastewater treatment and management.
   2. Solid and hazardous waste management.
   3. Solidification, stabilization, and environmental degradation of materials.
   4. Past research activities.

A. Water and Wastewater Management and Treatment Research:


Our water and wastewater research activities have focused on water chemistry and contaminant speciation; management of water resources; ground and surface water contamination by acid rock drainage (ARD); application of advanced oxidation methods, such as supercritical water oxidation and Fenton's reagent, for the destruction of organic contaminants in industrial wastewater for recycling. Some of our recent publications in this area include:

Environmental Engineering Teaching and Research at Tuskegee University
College of Engineering, Architecture & Physical Sciences

Environmental science and engineering teaching and research represent a major multi-disciplinary university-wide program within the College of Engineering, Architecture, and Physical Sciences. This program, funded by the U.S. Department of Energy, was created under the directorship of the Samuel Massie Chair of Excellence and housed in the Department of Chemical Engineering to support a BS degree option, as well as conduct graduate student training and research in all aspects of environmental science and engineering.

 

The mission of the program is the establishment of a sustainable nationally and internationally reputable research and training program in environmental science and engineering. Another desired outcome of this program is the maintenance of the training of a continuous stream of minority engineers at the undergraduate, graduate, and postdoctoral levels for the long term.

The Environmental Engineering undergraduate degree option in the Chemical Engineering Department provide fundamental training in the principles of environmental engineering to chemical engineering majors who are interested in a sub-specialization in the exciting discipline of environmental engineering.  In addition, the environmental engineering group maintains a world-class research and teaching laboratory, which is equipped with multi-million dollar state-of-the-art equipment. Some of the latest analytical and process equipment include:

    i. An Inductively Coupled Plasma-Optical Emission Spectrometer (ICP-OES).

    ii. A High Pressure Liquid Chromatograph, equipped with a mass spectrometer (HPLC/MS)

    iii. A gas chromatograph equipped with a mass spectrometer (GC/MS)

    iv. An Atomic Force Microscope (AFM) for nano-scale research

    v. A BET Surface Area and Pore Size distribution equipment

    vi. A scanning UV/Vis Spectrophotometer

    vii. A Contact Angle/surface Tension Meter

The environmental engineering group also conducts and administers the Tuskegee University undergraduate training program known as Partnership Award for the Integration of Research (PAIR). This project is funded by NASA Headquarters in Washington, D.C. Under this program, undergraduate students in Chemical Engineering and other science and engineering disciplines are paid a stipend while undergoing training in laboratory "Research Methods", during the regular semester or summer periods. Under the supervision of a faculty and mentor, students are allowed to participate and contribute to several ongoing environmental research projects. Funds for the environmental research program are provided by several granting agencies, including NASA, Office of Naval Research (ONR), Idaho National Engineering and Environmental Laboratory, Lockheed Martin Energy Systems, U.S. Department of Energy, and others. A few of the exciting ongoing research include:

    1. Behavior of materials under severe service environmenta.

    2. Nano-particle enhanced coatings for corrosion abatement

    3. Application of advanced oxidation methods for organics removal from wastewater.

    4. Evaluation of the stability of waste containment materials and waste-forms to microbial induced corrosion and degradation.

    5. Analysis of trace elements in lakes, soil, sediment and coastal waters

    6. Development of zirconia nanoparticles for ceramic and chemical process applications.

    7. Alternating current electro-coagulation for fine particles separation from aqueous systems

    8. Oxidative destruction of energetic materials in solution using Fenton's reagent

    9. ICP-OES analysis of heavy metal contamination in and around municipalities from industrial activities

In addition to research and teaching, the environmental engineering research group also conducts public outreach and public assistance programs to other institutions and organizations, such as The National Conference of Black Mayors; Paine College, Augusta Georgia; The City of Augusta, Georgia; The City of Hattiesburg, Mississippi.

Over the past few years, at least five students per year in chemical and environmental engineering degree programs have received tuition scholarship awards from the environmental engineering group with funding provided by the Office of Naval Research for undergraduate mentoring, research training, and tuition support. With one of the best environmental and chemical analytical capabilities of any environmental engineering and science program in the country, the environmental engineering program at Tuskegee University provides one of the best-equipped and exciting environments for teaching, research, and undergraduate training of any HBCU in the United States.
