Head of Department’s Welcome Address/Introduction:
On behalf of the Department of Pure and Applied Chemistry (PAC), I welcome you to our website. Our vision is to continue to grow in student population, staff strength, infrastructural development and research output. We realize how honourable our job is and the need to build a generation fortified with scientific knowledge, skills and comprehensive education in chemistry. Thus, we are committed and dedicated to this vision. PAC as a Department offers students some ways to engage with knowledge of Chemistry, including two bachelor’s degree programmes (B.Sc. Chemistry and B.Sc. Industrial Chemistry), some postgraduate programmes in Chemistry and hands-on research opportunities. The Department is equipped with a wide range of modern instrumentation necessary for the successful completion of any of our programmes.
We are privileged to have academic staff members whose research interests cut across nearly all the traditional sub-disciplines of chemistry. Over the years, we have built a reputation for a strong interdisciplinary research. No wonder our graduates all over the country and in the diaspora are having enviable careers in chemistry and beyond.
I wish you a productive and informative session as you take the time to browse our website. Do not hesitate to contact us if you have any questions.
– Dr. Adebanjo J. Anifowose
Ag. Head of the Department

Osogbo

Brief History:
At the inception of the University in September 2007, the pioneer Department started as the Department of Geological and Chemical Sciences which offered B.Sc. degrees in Geology, Industrial Chemistry and Biochemistry. The Department started with six pioneer staff (3 academic and 3 technical) and 10 students in 2007. The Department of Geological and Chemical Sciences was unbundled in the year 2012 into two: the Department of Geological Sciences (for B.Sc. Geology) and the Department of Chemical Sciences. This same year, the Department of Chemical Sciences added B.Sc. Chemistry to its programmes. In March 2018, the Department of Chemical Sciences was further split into two: the Department of Pure and Applied Chemistry and the Department of Biochemistry. The Department of Pure and Applied Chemistry (PAC) has been successfully running its academic degree programmes without losing any accreditation by the National University Commission (NUC). Today, the Department has grown in student and staff population, as well as infrastructural strength. This development is the springboard and solid foundation for the kick-off of postgraduate programmes in 2019, which have successfully produced quite a number of M.Sc. and PhD graduates.

Mission:
Our mission is to teach, train and transform our students into well-sought professionals, with sound knowledge of scientific principles and methods, who can compete favourably with their global counterparts for employment and research developments.

Vision:
Our vision is to be a centre of excellence in providing high-quality teaching and learning experiences in Pure and Applied Chemistry. This will result in giving back to the society thorough-bred entrepreneurial graduates who can engage in impactful research, as well as provide necessary social, industrial, environmental and scientific solutions that can lead to job creation.

Physical Development:
We have three functional laboratories that serve the academic programmes of the Department. The laboratories are well-equipped for undergraduate practical work and projects, as well as cutting-edge research activities for postgraduate studies. All the staff members have offices that are well-equipped with the required and necessary facilities. Adequate classrooms and seminar rooms are provided for the teaching and learning of the students. The library is well-equipped with modern facilities and up-to-date books, publications and periodicals necessary for teaching and learning.Research Activities:The Department has been a leading element in advancing frontiers in research and knowledge within and outside Nigeria. Many members of the Department have published in reputable international journals. The Department has cordial relationships with the Chemical Society of Nigeria (CSN), the Institute of Chartered Chemists of Nigeria (ICCON) the American Chemical Society (ACS) and other research bodies. Our research activities include: Synthesis of green nanoparticles (GNPs) and their applications in water treatment Environmental assessment of petroleum hydrocarbons and heavy metals from petroleum service stations on nearby soil and groundwater in Osogbo, Osun state Antioxidants, antimicrobial, anti-glycemic activities of synthesized calcium nanoparticles, zinc nanoparticles from leaf extract of Annona muricata Microplastics abundance and associated pollutants in vegetables: Implications on nutritional composition and bioactive components Measurement and toxicities of organochlorine pesticides (OCPs) in fish organs: A case study of Nile tilapia and spotted catfish harvested from Otin-River  Heavy metals in the sediment and water: Sources, ecological and human health risk Applications of Adansonia digitata, Ceiba pentandra and Ceratotheca sesamoids leaf- hydrocolloids as Rheology Modifier and Phytochemical agents in selected Human Diseases Management and control Investigation of the influence of fermentation on the nutritional values, functional properties and rheological attributes of soybeans Gold mining and its toxicity in aquatic habitat: Underscoring the importance of assessment
