CHAPTER ONE 1.0 INTRODUCTION 1.1 NICKEL 1.1.1 Occurrence Nickel (Ni) is a metallic element,with atomic number 28; atomic weight 58.69. Is a metal, which belongs to group VIIIB of the periodic table. The most important oxidation state of nickel is +2, although the +3 and +4 oxidation states are also known (Tundermann et al., 2005). Nickel resembles… Continue Reading
Spectroscopic method was used to determine quantities of carotene and ascorbic acid in carrot, cucumber, eggplant and tomatoes. The result shows that carrot has higher concentration of carotene =0.1430, follow by eggplant = 0.6950 and tomatoes = 0.0368 and cucumber has the least concentration of carotene =0.0139. The result also show… Continue Reading

F-Sulfo Fatty Methyl Esters sulfonates (F- MES) are new anionic surfactants obtained via sulfoxidation of fatty acid methyl esters (FAME) with SO2, O2, and ultraviolet light of appropriate wavelength. The designation of Φ refers to the random positioning of SO3 in the alkyl chain. In this work we summarize the most relevant results of… Continue Reading
Phytoremediation, based on the theory of botanic tolerance and accumulation of certain pollutant, is a new developing ecological technique primarily used to clean polluted environment. Blastofiltration is applied to phytoremediation of heavy metal polluted water at present. The study used castor, okra, melon and moringa seeds as… Continue Reading
Nickel amine carboxylate complexes were synthesized by reacting Ni(ii)chloride with ammonia, malonic and tartaric acid, which formed Nickel amine malonate and Nickel amine tartarate of blue and green crystal and the percentage yield are of both complexes are 62.65% and 62.83% respectively. The decomposition temperatures were 218o C… Continue Reading
The toxicity of heavy metals to humans as a result of long term exposure to pollutants consumer products such as cosmetics and other pollutants has been established. In this study, the levels of heavy metals in different cosmetic products commonly used among Kaduna Polytechnic students were assessed. The cosmetics were analyzed for heavy… Continue Reading
A comparative study was carried out for the determination of calcium and magnesium in milk and water melon (food sources of calcium and magnesium). Mixed standard solutions of calcium and magnesium (spike) were added to the samples before digesting with a mixture of concentrated nitric acid and concentrated hydrochloric acid (1:3). The calcium and… Continue Reading
