Waste Management and Potential Environmental Impacts of Occupational Vat Dyeing Practices in Kano Metropolis, Nigeria

Abdullahi S.^*, Adie,D. B., SALISU A

Industrial effluents in Nigeria are not treated in most cases but dumped into nearby open drainages and water bodies which is an exact situation in Kano metropolis. Vat dyes are the main causes of pollution in textile wastewaters and other industrial effluents. The aim of this paper is to investigate the waste management strategies of occupational dyers in Kano metropolis and determine the pote...

Removal of anthracene from solution using [Cu(INA)2] metal-organic frameworks synthesized by a solvent free method

Adedibu C. Tella^*, NWOSU F O, Sunday E. Elaigwu, Precious C. Ezeh, Vincent O. Adimula

Metal-Organic Frameworks (MOFs) [Cu(INA)2] were prepared by a solvent free method and were used for the adsorption of anthracene from solution. The [Cu(INA)2] MOFs were found to be good adsorption materials having good adsorption capacity. The maximum adsorption capacity for the [Cu(INA)2] MOFs was observed to be 22.73 mg/g for anthracene. The adsorption process favoured the pseudo-second order ki...

The Re-Imagination of Electrochemical Power: A Global Awakening and Thoughts from Obafemi Awolowo University, Ile-Ife.

Aremo Bolaji^*, Adeoye M. O., Obioh Imoh B, Okuwa Charles T, Oyinseye Shola I, Isadare Dayo A, Ayodeji Sodrudeen A, Abiodun Bukunmi J, Adeboye Odun A

From its humble beginnings as Alessandro Volta’s “voltaic pile”, electrochemical power (EP) has been power ing paradigm shifts in technology for the past 150 years. From the life-support systems in manned space explo ration of the 1960s, to the electric vehicles of the last 20 years, EP has been the unsung hero. EP is enjoying renewed focus and a flurry of R&D activities in today’s resource-const...

A Review of Some Welding Parameters and their Effects on the Heat-Affected Zone of Mild Steel Plate

S. E. Apeh^*, S. I. Kuye, O. R. Adetunji, Benedict Uche Anyanwu

Welding is one of the most important processes in manufacturing and construction industries. Various categories of welding exist and there are many welding processes available from which and industrial engineers can select for a particular application. The fusion category include the arc welding processes, resistance welding and gas welding methods; the non-fusion or solid state include cold w...

Computational Study of CO Adsorption Potential of MgO, SiO2, Al2O3, and Y2O3 Using a Semiempirical Quantum Calculation Method

Oyegoke Ademola^*, Jacob John Olusanya

Air pollution has been a vital subject attracting experts' attention towards the search for ways in which the pollution can better be controlled and minimized to avert the ongoing global warming and climatic changes experienced globally due to the release of poisonous gas regularly release to our environment. The bulk of the discharged gases are traced to the use of fossil fuel and the burning ...

Effect of Counterface Material on Tribological Behavior of AISI 304L Stainless Steel Under Marginally Lubricated Contact

Olofinjana Bolutife^*, Ajayi O. A, Lorenzo-Martin Cinta, Ajayi Ezekiel Oladele Bolarinwa

The properties of surfaces in contact are known to have significant influence on the tribological behavior of any tribosystem in different contact situations. In the present work, the effect of using different ball counterface material on the tribological behavior of AISI 340L stainless steel under marginally lubricated contact was studied. The frictional behavior was evaluated using a ball-on-...

Heavy Metals Status of Soil Around Waste Dumpsites in Ughelli Metropolis, Delta State

Ojebah C. K.^*, Uwague A., Edema O. G.

This study investigated the heavy metal status of soils around waste dumpsites in Ughell, metropolis, Delta State, Nigeria. Two different dumpsites were used for this study. For the metal analysis, soil samples were collected at 0-15cm depth. The soil samples were air dried for five days and sieved. 2.0g of the soil sample was digested with HNO3/HClO4 mixture and analysed for heavy metals (Fe, Pb,...

Effects of single super Phosphate and wood ash on biogas production using cow dung

Shaibu-Imodagbe E. M.^*, MUSA R, Igboro S. B., Alfa M. I., Ishaq A.

This study was carried out to examine the catalytic effects of Single Super Phosphate (SSP) with Wood ash on the production of biogas from Cow Dung. The study was carried out in four identical reactors to enable variation of the catalyst combination (100gSSP/50gWoodash, 150gSSP/75gWoodash and 200gSSP/100gWoodash). The research showed that SSP and Wood ash could reduce the lag phase in anaerobic di...

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-chem...

MAINA N. S^*, OKOKO O. J

In this research, Atili (blackdate) oil (Canarium Schweinfurthii) was extracted from the pulp using aqueous biphasic system (ABS) prepared from fixed concentration (40%) of polyethylene glycol (PEG) and varying concentrations of salt (di-sodium hydrogen phosphate (Na2HPO4)) at 10%, 20%, 30%, 40% and 50% respectively. The partitioning of the atili oil to the PEG-rich phase for the various combinati...
