Carbothermal Reduction Synthesis of Eggshell-Biochar Modified with Nanoscale Zerovalent Iron/Activated Carbon for Remediation of Soil Polluted with Lead and Cadmium

Pollution of soil with lead (Pb) and cadmium (Cd) has been gaining researchers’ attention because of their adverse health effects on the safety of the food chain and environmental health. Hence, their immobilization in the soil is of great interest to environmental scientists globally. In this study, eggshell-biochar modified with nanoscale zerovalent iron/activated carbon (ESB-nZVI/AC) were synthesized via carbothermal reduction synthesis and compared their immobilization efficiency at...

Adsorption Kinetics of Toxic Metals from Brewery Waste Water Using Adsorbent Prepared from Borassus aethiopum

A comparative study was carried out on the remediation of brewery effluent (Beff) using derived adsorbent (Untreated and treated) and commercial activated carbon. Preliminary study and characterization of the brewery effluent, derived adsorbent and commercial activated carbon was recorded, with result showing physico-chemical properties of the effluent falls within, lower and higher than discharge limit outlined by NESREA and WHO. Result of the physico-chemical and instrumental character...

Bioelectricity Production from Abattoir Wastewater Using Microbial Fuel Cells Connected in Series

In a bid to further study the possibility of producing bioelectricity from microbial fuel cell (MFC), this study aims at increasing the production of bioelectricity in abattoir wastewater. The wastewater from abattoir was used to construct three different microbial fuel cells and they were connected in series. The voltage of electricity produced was recorded over the period of three days. The physiochemical property of the wastewater was determined. Also the microorganisms present in t...

BIOELECTRICITY PRODUCTION FROM WASTEWATERS USING MICROBIAL FUEL CELL

Electricity supply in Nigeria has been a recurring decimal as huge amount of capital is involved. The aim of the study is to produce bioelectricity in a microbial fuel cell (MFC) from wastewaters. Wastewater from abattoir, fish pond, and stream were used to construct a microbial fuel cell and their physiochemical and microbiological properties were determined and the voltage of electricity produced was measured. Wastewaters were separately inoculated using pour plate to determine bacterial...

SOLAR ENERGY: POTENTIAL FOR MITIGATING DEVASTATING EFFECTS OF CLIMATE CHANGE

ABSTRACT Climate change has been identified as one of the greatest challenge by all the nations, government, business and citizens of the globe. The threats of climate change on our green planet ‘Earth’ demands that renewable energy share in the total energy generation and consumption should be substantially increased as a matter of urgency. Nigeria’s energy development programme has been put under severe pressure with the ever-increasing demand supply gap. Due to predominance of fossil...

SAVING THE DYING PLANET EARTH

Planet  earth  is  being  endangered  by anthropogenic  activities  ranging from industrial  activities  to  seemingly innocous activities  such  as  use  of  herbicides  on  farms.There  are possibilities  that the  resources  of the  earth  may  not be  sufficient   to  sustain the  needs   of  future  generations.There  are  also possibilities  that the  earth may become in conducive for human habitation  due  to  emission of  dangerous  gases  and...
