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… Continue Reading
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
Antibiotic resistance has become one of the major problems facing humanity. The need for new antimicrobials has been increased dramatically. Plants are considered as a major sources of new antibiotics due to the presence of phytochemicals. In Nigeria and other developing countries medicine plant materials have been used to treat various… Continue Reading
The soils and leaves of fluted pumpkin (Telfairia occidentalis), African spinach, 'Green' (Amaranthus hybridus) and water leaf (Talinum triangulare) were collected as randomly composite samples from four (4) different study locations of two (2) each from Owo Local Government Area and Etsako-West Local Government Area. The samples were… Continue Reading
The synthesis, characterization and preliminary antimicrobial studies of some novel Schiff base ligands; N,N/ - Bis(2-hydroxybenzylidene)-1,4-phenylenediimine(M) and N,N/ - Bis(4-dimethylaminobenzylidene)-1,4-phenylenediimine (N) were undertaken. It was prepared by the condensation reaction of 1,4-phenylenediamine with… Continue Reading
The effects of temperature, dielectric constant and catalysis in the kinetics of the oxidation –reduction reactions (involving electron transfer) of N-(2-hydroxy-ethyl) ethylenediammine- N’,N’,N’-Triacetatocobalt (II) by Cu2+ cation were determined. The dielectric constant was decreased from 63.05 to 43.18 and it was found that… Continue Reading
The potentials of Adansonia digitata root (ADRP) and stem powders (ADSP) and the stem activated carbon (ADSAC) for adsorption of Pb2+, Cd2+, Cu2+ and Co2+ from aqueous solutions were investigated. The activated carbon was prepared via chemical activation using ZnCl2 as the activating agent. Physico-chemical analysis of the adsorbents… Continue Reading
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.
