Comparison of Percentage Reduction of Total Petroleum Hydrocarbon on Treatment Using Bryophylum pinnatum Leaf: The Concept of Alcohol and Water as Solvent for Constituents ExtractionBy Abraham Peter Ukpaka, Joy Chukwuemeka Peter Ukpaka, Victor Chukwuemeka Ukpaka, Chukwuemeka Peter Ukpaka
Abstract: Investigation on the comparison of percentage reduction of total petroleum hydrocarbon on treatment using Bryophylum pinnatum leaf was indeed, considered by using the concept of alcohol and water as solvent for constituents’ extraction. The extracts were introduced into the various bioreactors set-up and the Total Petroleum Hydrocarbon (TPH) concentration monitored with increase in contact period. The investigation revealed decreased in TPH concentration with increased in the percentage reduction of the …

Overview of Atomic Structure of Metals in Group 1 ElementsBy Victor Chukwuemeka Ukpaka, Abraham Peter Ukpaka, Ukpaka C.P.
Abstract: This study discussed the basic atomic features of Group 1 elements—lithium, sodium, potassium, rubidium, cesium, and francium—by concentrating on their electronic configurations, atomic radii, and ionization energies. The article gives a thorough investigation of how these variables contribute to the chemical and physical characteristics of alkali metals. The data demonstrated that when the atomic number increases, the atomic radius likewise increases, whereas the ionization energy drops. These developments are ascribed …

The Integrity of Eadic-Hofstee Plot Model to Predict the kinetic Parameters of Crude Oil Degradation using Vernonia amygdalina StemBy Abraham Peter Ukpaka, Victor Chukwuemeka Ukpaka, Joy Chukwuemeka Peter Ukpaka, Chukwuemeka Peter Ukpaka
Abstract: The integrity of Eadic-Hofstee concept was tested for the determination of the functional coefficients and parameters of crude oil degradation kinetics. The techniques enhanced the relationship between the substrate divided by the specific rate of the substrate degradation against substrate concentration (TPH). The investigation reveals the values of the biokinetic parameters of maximum specific rate of substrate degradation (Vmax) and the equilibrium constant values of the substrate degradation (Ks). The …

Evaluation of Lemon Grass (Cymbopogon Citratus) Performance for Petroleum Hydrocarbon Degradation in Soil EnvironmentBy Abraham Peter Ukpaka, Ukpaka, C. P
Abstract: The evaluation of lemon grass (cymbopogon citratus) performance for petroleum hydrocarbon degradation in soil environment was monitored with respect to contact time or period of exposure. Models were developed in this research to demonstrate the potential of the first-order kinetic, Michaelis Menten and the LineWeaver Burk Plot, and the evaluation of the effect of the biostimulant dosage was monitored in accordance the total petroleum hydrocarbon degradation. The performance of lemon …
