Determination Of Surface Charge Density Of Α-Alumina By Acid - Base Titration

ABSTRACT. The surface charge density (σo) of colloidal alpha-alumina suspended in various 1:1 electrolytes was measured using acid-base titration. An auto titrator capable of dispensing accurately 25 ± 0.1 µL of titrant was used. The pH and temperature in the titration cell were monitored using single-junction electrodes and platinum resistance thermometers, respectively. A constant supply of nitrogen gas in the cell was used to maintain inert conditions. The whole set-up was interface...

Low Temperature Glycerolysis as a High FFA Pre-Treatment Method for Biodiesel Production

ABSTRACT A novel low-temperature glycerolysis process for lowering free fatty acid (FFA) in crude jatropha oil for alkali catalyzed transesterification has been developed. The response surface methodology (RSM) based on the central composite design was used to model and optimize the glycerolysis efficiency under three reaction variables namely; reaction time, temperature and glycerol to oil mass ratio. The optimum conditions for the highest glycerolysis efficiency of 98.67% were found to ...

Effects of Castor Oil on the Physical Properties of Polyether Based Flexible Polyareahane Foam

ABSTRACTA preliminary study was made on the effect of castor oil on the properties of polyether based polyurethane foam such as rising time, density, hardness tensile strength, compression, elongation and heat aging. The castor oil was introduced into the polyurethane foam by partially substituting it for silicone oil through seven experimental set up, based on the laboratory mix formulation on 5OOg polyether based polyol with 0%, 20%, 40%, 50%, 60%, 80% and IOO% castor oi...

Evaluation of the Application of Wastewater and Bioventing System for the Treatment of Crude Oil Contaminated Soils

Environmental pollution is a form of land degradation which has contributed immensely to the reduction of available arable lands and could lead to the total annihilation of the ecosystem if not effectively mitigated. Bioremediation technology offers a biological means which provide an eco-friendly and cost-effective approach for soil remediation in contrast to physicochemical methods. This study aims to evaluate the application of wastewaters and air-injection ...

Evaluation of Industrial and Municipal Wastewaters as Bio-Stimulants for the Treatment of Crude oil Contaminated Soils

The prevalence and high rate of soil contamination have contributed immensely to the reduction of arable lands which might lead to the total annihilation of the ecosystem if not mitigated. Bioremediation employs microorganisms that offer a sustainable approach for the remediation of contaminated soils. This study focus on the evaluation of industrial (brewery) and municipal effluents for the treatment of crude oil-contaminated soil. A microcosm containing 1kg of crude oil-contaminated soil ...

Synthetic method dependent physico- chemical properties and electrochemical performance of Ni doped Synthetic method dependent physico-chemical properties and electrochemical performance of N

Nickel doped zinc oxide (Ni/ZnO) nanostructures have the potential to improve the performance of electrochemical capacitors. This study investigates the preparation of Ni/ZnO nanomaterials by facile co-precipitation (CPM) and hydrothermal (HTM) methods. The effect of the synthesis methods on the optical, structural, chemical and morphological properties on ZnO products is investigated using ultra violet (UV)-visible spectroscopy, X-ray diffraction (XRD), field emission scanning electron micro...

OPTIMIZATION OF CONDITIONS FOR THE PRODUCTION OF ACTIVATED CARBON FROM MANGO KERNEL SHELL USING BARIUM CHLORIDE AS THE ACTIVATING AGENT

ABSTRACTThis study was conducted to remove mango shell waste which is one of the seasonal environmental nuisance items and recycle it as a precursor for the production of activated carbon. Discarded mango shells were sourced from local vicinity, and they were washed thoroughly to remove dirt, sundried and reduced to smaller sizes. Two-Level Factorial Design under Factorial Methodology of Design Expect (10.0.1) software was employed to optimize interaction of impregnation ratio (0.033 - 0.167 ...
