  Some Plant Extracts Potential in Cleaning Soil Environment Contaminated with Petroleum Hydrocarbon

  By Ukpaka Chukwuemeka Peter, Okwu Kingsley

  Abstract: This research considered the trend of some agro-based plant extracts obtained from paw paw, mango and aloe-vera leaves for the purpose of treatment of a contaminated soil environment. The potential of each agro-based plant extract was tested with respect to its ability in the area of petroleum hydrocarbon clean-up in soil environment. The impact of the variation on the pH on each of the bioreactor set-up was monitored and the …

  Monitoring the Effectiveness of Water-Based Plants for the Inhibition of Metal

  By Ukpaka Chukwuemeka Peter, Chioma Onwubiko Hosanna, Okwu Kingsley

  Abstract: The temperature performance profile of the plant extracts shows that inhibition efficiency increased with increasing temperature of the system until at about 323K at 9.00hrs immersion time where a decline in inhibition efficiency occurred implying the opposite at higher temperatures and longer immersion time. Corrosion rate parameters changed with rise in temperature and exposure – immersion time. Plots of rates of corrosion against the volume(s) of the test inhibitor(s) in …
