Activated carbons were thermally prepared from Hura Crepitan L. seed shells. Zinc chloride (ZnCl2) and phosphoric acid (H3PO4) were separately used as the activating agents. The activated carbons obtained were characterized by determining the percentage yield, moisture content, ash content and percentage fixed carbon. The adsorption of methylene blue by the activated carbon was done using 0.1 to 0.5 g of the activated...

The effect of Commiphora africana (CA) gum exudates on the corrosion of mild steel in 2.5 M Na2CO3 has been studied using weight loss (gravimetric) and thermometric methods at 303 and 333 K. Results obtained suggest that C. africana acts as a good corrosion inhibitor as the inhibition efficiency increased with increase in the concentration of the inhibitor. A decrease in the %I was observed with increase in temperature...

The proliferation of industries has led to increased presence of heavy metals in our environment and, humans are continually exposed to these heavy metals through their engagements in different industrial activities. The current study is designed to make a comparative assessment of the level of heavy metals (Pb, Cu, Ni, Zn, Al) in the hair scalp of humans living in industrialized and unindustrialized cities of Port...

The toxicity of Vernonia amygdalina root and enzymatic activities of Crinum jagus extracts on guinea pigs were investigated. The cold water, n-hexane, ethyl acetate and methanol extracts were used to evaluate the effect of VA root poison on the aspartate transaminante, alanine transaminante and alkaline phosphatise enzymes activities in the serum/liver of guinea pigs. No death of guinea pigs were recorded neither in the...
