Iron Pillared Clay for Sorption of Toluene in Aqueous Solution: Kinetics and Equilibrium StudiesBy Emole, P. O, Kelechi Emmanuel Onwuka, Emeruwa, C. N.
Abstract: The adsorption of toluene using unmodified and Fe-pillared clay were investigated in this study using UV/Visible, FT-IR spectroscopic measurements and batch adsorption process. The framework vibration of the clay before and after pillaring were determined using FTIR spectra. Effect of Contact time and initial and various concentration of toluene at constant temperature were investigated. The experimental data were studied using equilibrium isotherm (Langmuir and Freundlich) and kinetics models (pseudo first …

Risk Assessment of Polychlorinated biphenyls (PCBs) in Fish Samples from Otamiri River, Imo State, NigeriaBy Kelechi Emmanuel Onwuka, Okechukwu C. Atasie, Solomon O.E. Okereke, Nnamdi E. Enenwa, Ifeanyi A. Onuabuchi, Chibuike E. Osuigwe
Abstract: The presence of Polychlorinated biphenyls (PCBs) in water poses human and ecological health risks in Nigeria. Polychlorinated biphenyls present in three fish species (T. Zilli, E. Fimbriata and C. Nigrodigitatus), and its related health risk via consumption of fish from Otamiri river in Imo State Nigeria has been duly investigated in this study. A risk quotient (RQ) for fish consumption was applied to evaluate the related health risk. A total …

Chemical Compositions of Three Economic Tuber Crops Grown In South East, NigeriaBy Kelechi Emmanuel Onwuka, Precious O. Emole, Nnamdi E. Enenwa
Abstract: Yam (Dioscorea spp) are known for their climbing properties, twining stems which coils readily around a stake and exhibiting glaborous leaves. Via root system, they are perennial but are usually grown as annual crops. Yam is economically important because it serves a staple food for millions of people in Africa, as well as Nigeria. There is limited information on nutrients composition of Nigerian foods. As a result, nutrients intake from …
