Preparation and Assessment of Biodegradable Polyurethane Foams from Sugar Bagasse

Lawrence Ekebafe*, Akpa F. A. Omolade, Olugbemide David A.

This study is focus on producing polyurethane foams that would have same or better properties compared to the conventional and still be able to undergo biodegradation upon disposal. Microfibers were isolated sequentially using nitric acid, sodium hydroxide and hypochlorite bleaching under different extraction conditions. The cellulose microfibers extracted were characterized for their compositi...

Exploiting the remediation capacities of microbiological strains and membrane technologies for the treatment of textile dyes effluent

Shinkafi M. S.*, GALADIMA M.S, Mohammed I. U., Hassan A. S., J. M. Hayatu

The present work evaluates the potentials of using indigenous microbial strains isolated from wastewaters of an effluent treatment plant of a Textile Industry and the feasibility of employing nanofiltration (NF) membrane and reverse osmosis (RO) systems as an alternative treatment method of textile wastewater discharged from textile industry. Experiments were performed in a laboratory - scale s...

Elucidation of microbial decolourization and degradation efficiency of recalcitrant-carcinogenic azo dye congo red by novel bacterial strains

Shinkafi M. S.*, GALADIMA M.S, Mohammed I. U., Hassan A. S., J. M. Hayatu

Novel bacterial strains capable of decolorizing textile dyes were isolated from dye contaminated soil obtained from the vicinity of African Textiles Industry Challawa, Kano - Nigeria. The Carcinogenic azo dye Congo red used widely in various industrial processes poses terrific environmental concern, causing major health problems to human beings. In the present study, decolourization of Congo re...

Mechanical Modelling of Bamboo Sawdust/polyester Composites Fabricated by Hot Pressing Method

Ofem Michael Ikpi*, Ubi Paschal Ateb, Christian Christian Adi, Ekpe Ubong Pius

Bamboo fibres of 1 to 3 mm sizes were milled to particle size of approximately 100μm using a hammer mill. The  bamboo sawdust (BS) was chemical treated using NaOH of concentration 6 % wt/v for 72 h at room temperature.  Dried bamboo sawdust was mixed with polyester at different weight ranging from 0 % to 24 % wt. %. The com posites were tested for the tensile properties. Theoretical mechanical equ...

Comparative synthesis of sodium silicate from rice husk and kaolin

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

Sodium silicate in powdered form was successfully synthesized from both rice husk ash and Kankara kaolinite clay. The impure nature of both monomer and NaOH used does not seems to hinder the depolymerization reaction viz-a-viz product formation. The crystallinity of sodium silicate produced tends to increase with reaction time, temperature, and Na2O/SiO2 ratio. About 93% crystallinity for as sy...

The possible modulatory effects of kolaviron on arsenite-induced hepato-toxicity in experimental rats

OLUFUNMILAYO HANNAFI O*, THEODORE AKUNNA

The effects of kolaviron , an active component of Garcinia kola seeds were investigated on sodium arsenite-induced hepatotoxicity in rats. Administration of a single dose of sodium arsenite (10mg/kg body weight) orally, increased the activities of serum marker enzymes-Aspartate aminotransferase (AST) and Alanine aminotransferase (ALT). This also led to increase in lipid peroxidation and reducti...

Properties of chemically modified Baobab pod/Sisal Fibre reinforced Low Density Polyethylene Hybrid Composite

ISA M. T*, Shehu U., Aderemi B. O., Bello T. K., Audu H. I., Shittu U. M., ATTA A. Y

The present study determined the effect of sodium hydroxide (NaOH) treatment on the properties of baobab pod/sisal fibres reinforced low-density polyethylene (LDPE) hybrid composites. Used to treatment the fibres, were different concentrations of NaOH 2 -10 wt% at 2 wt% interval. The hybrid composites were compounded using two roll mills machine and compressed in a mold using hydraulic press a...

An assessment of the metals accumulated in newly weaned mice after ingesting ‘Nzu clay’ using neutron activation analysis and atomic absorption spectroscopy

Omoniyi K. I.*, OKUNOLA O. J

Nzu clay’ is a geophagious clay consumed in Africa for some medicinal purposes. This study reports the level of accumulated metals in mice that ingested ‘Nzu clay’ for 14 days. Eight female mice (10 ± 2 g) were each fed 0.02 g of ‘Nzu’ mixed with Bendel Plc Feed per day. The ‘Nzu clay’ contained 2.900 mg/kg Pb and 2.143 mg/kg Cd, while the experimental mice accumulated 0.893 mg/kg of Pb and 2.7...

Physicochemical properties of terminalia avicennioides (ta) and anogeissus latifolia (al) gum

Omoniyi K. I.*, AMEH P. O, USMAN U

The work reports the physicochemical properties of gum exudates from two Combretaceae tree species (Terminalia avicennioides (TA) and Anogeissus latifolia (AL)) determined by standard methods. The gum exudates exhibited differences in physicochemical qualities. The physicochemical properties of the gum were in the following ranges: moisture (11.3 - 11.5%); swelling capacity at 30oC (11 - 13%); ...

Synthesis and characterisation of Azo dyes derived from Naphthalen-2-ol and their washfastness properties on cotton, wool and nylon fabrics

Abdulraheem Giwa*, Mela A. C., Umar S. M.

A series of azo dyes was synthesised by coupling reaction of napththalen-2-ol with diazotized 4- sodiumphenolate, 4-Nitrophenylazo and 4-Chlorophenylazo respectively, as diazo components. The characterization of the dyes was carried out by GC/MS analysis. The solubility of dyes in the visible absorption spectra was also determined. The dyeing performances of the three dyes were assessed on cott...
