An environmental management systems (EMS) is a tool used to implement a structure programme of continual improvement in environmental management system. It is a tool for managing the impacts of organization’s activities in the… Continue Reading
CHAPTER ONE INTRODUCTION 1.1 BACKGROUND OF STUDY 1.1.1 CORROSION Corrosion is defined as a natural process, which converts refined metal to their more stable oxide. It is the gradual destruction or degradation of materials (usually metals) by chemical reaction with their environment which are most likely inevitable. Corrosion is a natural and… Continue Reading
CHAPTER ONE INTRODUCTION 1.0 GENERAL INTRODUCTION Energy is a fundamental pillar of modern society as well as being an essential building block for socio-economic development (UNIDO, 2007). The awareness of the imminent depletion of fossil fuels coupled with a global energy crisis has stimulated interest in the research for alternative… Continue Reading

SYNTHESIS AND 1 HNMR CHARACTERIZATION OF Co(II) AND Fe(II) COMPLEXES OF MIXED SCHIFF BASE LIGAND DERIVED FROM SALICYLALDEHYDE AND 2-HYDROXY-1-NAPHTHALDEHYDE WITH 2-AMINOPHENOL A RESEARCH PROJECT BY NKEMJIKA, EMMANUEL EKE 12/SC/CH/256 SUBMITTED TO DEPARTMENT OF CHEMISTRY FACULTY OF SCIENCE UNIVERSITY OF UYO, UYO AKWA IBOM STATE IN PARTIAL… Continue Reading
The efficiency of acid modified locust bean pod (ALBP) as low cost adsorbent to remove Rhodamine-B (Rh-B) dye from aqueous solution was studied. The morphology, functional groups and elemental analysis of the adsorbent were investigated by SEM, FTIR, pH (pzc), and Boehm titration analytical techniques. Operational parameters such as… Continue Reading
This research work is on the preliminary determination of active components in bitter leaf root ( vernonia amygdalina ) in the treatment of diabetes. Deficiency of hormone (insulin) causes diabetes mellitus, a disease due to too much of sugar being present in the blood. This is because without insulin in the body, the result is that sugar… Continue Reading
CHAPTER ONE INTRODUCTION 1.1 Background to the Study Cassava (Manihot esculenta crantz) is a perennial crop native to tropical America [1, 2]. It originated from Brazil and was introduced to Africa by Portuguese traders in the 16° century… Continue Reading
