FABRICATION OF EPOXY BASE PARTICULATE COMPOSITES FILLED WITH AFRICAN MESQUITE PODS FOR CEILING BOARD APPLICATION

Aliyu Jibril*, Ishiaku S. U., Musa M. B., Abdulraheem Giwa, Yusuf L O

The extensive deforestation of African mesquite trees and the significant waste produced due to their perceived economic value have spurred research into using their solid waste in construction applications. This study investigates the utilization of African mesquite waste pods as a filler in epoxy composites. Composites were prepared using hand mi...

Electrical Energy Management in the Textile Industry

Iliya, E.B.*, Abdulraheem Giwa, Ibrahim H.D

The sources and pattern of supply of electrical energy in a typical medium-scale Textile manufacturing outfit was studied over three months. The frequency of power failure from municipal supply was 408, amounting to 929.64hrs power outage. Low voltage was recorded 98times totaling 156hrs. Much of these hours were covered by in-house supply. Compari...

Synthesis and Application of Monoazo Disperse Dyes Derived from 4-amino-Nhexadecyl-1, 8-naphthalimide and their Dyeing Performance on Polyester Fabrics

Magaji I. Y*, Abdulraheem Giwa, Bello K.A.

A series of monoazo disperse dyes were synthesized using 4-amino-N-hexadecyl-1, 8-naphthalimide by coupling with different substituted electron rich arenes in appropriate reaction conditions. The synthesized diazo component and the dyes were purified by recrystallization method. The structures of the diazo component and the dyes were confirmed ...

Synthesis and Application of Monoazo Acid Dyes Derived from 5-amino-4- cyano-2-methyl-N-phenylthiophene-3-carboxamide on Chrome Tanned Leather and Nylon 6,6 Substrate

Magaji I. Y*, Abdulraheem Giwa, Bello K.A.

A series of new mono azo dyes have been synthesized in moderate yield from diazotization of thiophene and coupling with R, H, J and ϒ acid. The dyes were characterized by spectral studies. The dyeing potentials were assessed by applying them on chrome tanned leather and nylon 6,6 substrates. The dyes were found to give shade of red dark blue and da...

Study of the Adsorption of Anionic Dye onto Activated Bone Char

Jibril, A.*, Bukhari M. M., Abdulraheem Giwa, Ibrahim H.D

The adsorption of reactive dye onto activated carbon obtained from cow bones was investigated. The effects of dye concentration and pH on the adsorption of the dye onto the activated carbon were similarly investigated. The optimum adsorption was obtained at dye concentration of 45 mg/L and pH 6 respectively. Langmuir and Freundlich adsorption isoth...
