Palm oil has been part of human diet for more than 5000 years. Nigeria is currently the fifth world’s leading producer of palm oil (Nnorom, 2012). The palm oil industry is a major agro based enterprise in Nigeria especially in the southern part where palm oil trees are found both in the wild land plantations (Nwaugo et al., 2008). For...

ABSTRACT The improvement of the combustion properties of coal and biomass by blending and carbonization was investigated. Proximate and ultimate analysis of coal, sawdust, corn cob and their blends were carried out using ASTM methods. The proximate and ultimate analyses were repeated on the five blends after carbonization at 500o C for one hour.... Continue Reading
ABSTRACT The removal of Pb(II) ions from aqueous model solution using zeolite has been investigated under different operational parameters like heavy metal ion concentration, adsorbent amount and particle size. The zeolite used was synthesized and characterized using SEM and XRD analysis. The equilibrium adsorption capacity of zeolite used for... Continue Reading
ABSTRACT Polycyclic Aromatic Hydrocarbons are some of the known organic pollutants resulting from incomplete combustion of organic matter. They have been found to be carcinogenic, mutagenic and teratogenic. Much of the previous works on Polycyclic Aromatic Hydrocarbons have been on foods, water, dumpsites and on soil generally. However, this study... Continue Reading

ABSTRACT Zeolite crystals were synthesized by mixing sodium silicate and sodium aluminate to obtain aluminosilicate gel which was further treated hydrothermally to obtain the final product. The zeolite crystals were characterized by x-ray diffraction (XRD) and scanning electron microscopy (SEM). The XRD result identified the synthesized crystals... Continue Reading
ABSTRACT The azo-ligand, 1,5-dimethyl-2-phenyl-4-[(E)-(2,3,4-trihydroxylphenyl) diazenyl]- 1,2-dihydro-3H-pyrazol-3-one (H3L) and its Zn(II) and Cd(II) complexes have been synthesized and characterized based on stoichiometric, molar conductance, electronic and infra-red spectral studies. The results showed that H3L reacted with the metals in 2:1... Continue Reading
ABSTRACT The synthesis of five mono- and five bis-alkynylated derivatives of quinoline-5,8-diones is reported. The intermediate 6,7-dibromoquinoline-5,8-dione was obtained by nitrosation of 8- hydroxyquinoline, followed by reduction and subsequent bromination and oxidation. The coupling reaction of 6,7-dibromoquinoline-5,8-dione via... Continue Reading
ABSTRACT The synthesis of N-heteroaryl substituted benzene sulphonamides and evaluation of their biological activities are reported. Synthesis was achieved by the reaction of benzene sulphonyl chloride and substituted amino heterocycle in dry pyridine. The structures of synthesized compounds were assigned by spectroscopic methods. The eight (8)... Continue Reading
ABSTRACT A simple and sensitive spectrophotometric method for the determination of paracetamol was explored, using zirconium(IV) and vanadium(V) oxides. The method was based on the oxidation of paracetamol by zirconium(IV) and vanadium(V) in alkaline and acidic media respectively. The stoichiometric studies indicated a mole-ratio of 1:1 for the...

Abstract This study is aimed at determining the concentration of gold in the gold ore in lujinjimubende district. Currently investing in gold mining is taken as a riskyinvestmentbecause people are not sure of the concentration of gold in lujinji and also the depth where gold concentration is high. The results of this research gave the... Continue Reading
ABSTRACT The total alkaloid, tannins contents and antiulcer activity of the extracts from four selected medicinal plants were investigated. The total alkaloids content (TAC) was evaluated according to the chloride colometric method in which atropine was used as standard. While the total tannins content (TTC) was also determined using Folin... Continue Reading
Extraction of oil from plants and animals’ source for production of fat liqour to render the leather soft by a sort of lubricating the fibres after tanning is being a practice for long. However, the oils and fats that were formerly used almost exclusively are now becoming scarce and expensive, thus there are need to source for alternative... Continue Reading
ABSTRACT The Schiff base ligand, 2-[(E)-[{3--[(2-hydroxybenzylidene)amino]phenyl}imino)methyl]phenol was synthesized by condensing 1,3-diaminobenzene and 2-hydroxybenzaldehyde in absolute ethanol.
