Production of citric acid from lemon and cassava waste peels

NWOSU F O*, KAREE A O

The high demand for citric acid by many industries cannot be over emphasized. Presently, 70 % of the total citric acid produced globally is consumed by food industries, 12 % by pharmaceutical industries and the remaining 18 % by other industries. Moreover, rapid increase in food/beverage industries in Nigeria with no known company producing citric acid in Nigeria makes its scarcity severe. Cass...

Investigation and comparison of the optimal condition for the production of biodiesel from shea butter oil and groundnut oil using homogeneous catalysis

YUSUF N*

Due to the depletion of world petroleum reserves and increased environmental concerns, recent interest in alternative source for petroleum-based fuels has been developed. Biodiesel arose as the potential candidate for a diesel substitute due to the similarities it has with petroleum-based diesel. Chemically biodiesel is monoalkyl esters of long chain fatty acids derived from renewable feedstock...

Physicochemical Parameters and Heavy Metals Characterization of Soil from Okpella Mining Area in Edo State, Nigeria

Edema O. G.*, Abel Inobeme, Olori E., Adekoya M. A., Obigwa P. A.

The present study examines the physicochemical parameters and heavy metal contents of soil from Okpella Mining  Area in Edo State. Top soil samples and   control  samples from about 200m from the mining area were analyzed for  their heavy metals content using Atomic Absorption Spectrometer (AAS) techniques. The pH, electrical  conductivity and organic matter were determined using standard procedur...

Intercalation of anionic surfactants into Zn-Al hydrotalcites of varying composition: preparation and characterization

OMONMHENLE S. I*, SHANNON I J

The synthesis and characterisation of Zn-Al hydrotalcite-like compounds intercalated with sodium dodecyl sulfate (SDS) and sodium dodecylbenzene sulfonate (SDBS) have been investigated in details. The synthesis has been carried out following calcination-regeneration method. The organic modification was intended to derive hydrotalcite-like compounds appropriate for various applications such as ...

Advances in Sol-Gel Synthesis of MgZr4(1-x)Hf4xP6O24 (x = 0, 1) Solid Electrolytes for Electrochemical Devices

Mohammed Alhaji Adamu*, Girish M Kale

The potential solid electrolytes, MgZr4P6O24 and MgHf4P6O24 were prepared using modified novel sol-gel method. Structural and electrical properties of the solid electrolytes were determined. TGA-DSC analyses indicated that the pure dried xerogel powders, when calcined at 900 oC converts to pure single phase MgZr4P6O24 and MgHf4P6O24 nanopowders with excellent crystallinity. Pellets of 13 mm diamet...

Zeolite NaY from Kankara Kaolin using Commercial Grade Chemical: Effect of Crystallization Time and Temperature

Ajayi O. A*, Mamman J., Adefila S. S.

Zeolite Y was synthesized using commercial sodium hydroxide and Kankara kaolin as starting material in the presence of sodium silicate formed from kaolinite clay. Synthesis was done at 90°C, 95°C and 100°C for crystallization time of 12, 18, 24 and 36 hours. Results showed that commercial sodium hydroxide could be used to successfully produce zeolite Y from Kankara kaolin when gelling ratios of...

Electrochemical and structural characterization of nickel oxide filled activated carbon for upercapacitor electrode application

Ahmed T. O.*, Ogunleye O. O., Galadima I. A., Sulle B. A., Bello A.

We have demonstrated that activated carbon could be produced via microwave-assisted activation at a much shorter time (ranging from 2-5 min) and reduced cost compared to the conventional activation method embraced by most researchers in the production of activated carbon. The research work is not only limited to surface chemistry and adsorption studies but also includes structural, microstructu...

Electrochemical Impact of Zinc-Magnesium Oxide-Cellulose Nano-particle Electrodeposited Composite Coatings on Low Carbon Steel in Sodium Chloride Media

Benedict Uche Anyanwu*, Owoeye S.O., Olamide O.O, Olaitan K.L, Anibaba A.D, Yussouff A.A, Okpako O

Low-carbon steel (LCS) is applied in numerous engineering applications, such as construction, automobile  manufacturing, and product and component manufacturing, due to its unique mechanical properties. They are readily  available, hence are very cost-effective when considered in any application. However, they are usually affected by  corrosion when exposed to chloride-i...

Extraction and characterization of oil from African star apple (Chrysophyllum albidum) seeds for utilization in the leather industry

Bulus Habila*, Dadah J.S, Salim Ahmed Sule, Sunday Ojih, Igbehinadun Olajide J., Kadanga Beatrice, Zakari Abdullahi, Kogi Cecilia A

The leather industries in Nigeria depend largely on imported fatliquors at exorbitant rates and that has affected the leather value chain, to avert this, there is the need to look into our indigenous plants to make this product available. In this light African star apple (Chrysophyllum Albidum) seed was considered for its affordability and availability. The seed was collected and some physico-c...

Synergizing the Electrical Conductivity of Functionalized Woven Polyester (PET) with In-Situ Polymerization of Aniline

ILIYA E. B*

Polyester fabric (100%) was electrically functionalized by dyeing in pristine multi-walled carbon  nanotubes in Miranol at different shades (0.1 - 6.0) % (owf). Aniline was then polymerized within each  of the fabric samples using Sulphuric acid and Potassium peroxydisulphate at oxidant: monomer ratio  1.25 and LR 40:1. After polymerization, the conductivity percolation threshold reduced from 1.0 ...
