Degradation Efficiencies of the Total Petroleum Hydrocarbons (TPHs) in the Soil Amended with Palm Bunch Ash and Tween 80 in Ibenomo L.G.A, Akwa Ibom State
Abstract
The degradation efficiency of total petroleum hydrocarbons (TPHs) in the environment of Ibeno Local Government Area, Akwa Ibom State, Nigeria was studied. An experimental design method was used for this research. A random sampling technique was applied to collect the samples (APHA, 2005). Fifteen (15) topsoil samples from a depth of 0-20 cm were randomly gathered from fifteen (15) different locations in the study area using an auger. These samples were mixed in a six-liter plastic bucket to create a composite sample and stored at 4 °C in a refrigerator. A standard method for analyzing soil samples was followed to assess Total Petroleum Hydrocarbons (TPHs) as outlined by the World Health Organization (WHO). The absorbance of each sample A, B, C, and D was measured and recorded using a UV-VIS spectrophotometer (UV2500-1198). Different concentrations of palm bunch ash (PBA) (ranging from 0.0 g to 50.0 g), Tween 80 (50.0 g), and a combination of PBA + Tween 80 (25.0 g) were added to samples A, B, C, and D, with A serving as the control. The concentrations of TPHs were measured at 20-day intervals over a period of 60 days. The data were analyzed using a first-order kinetic model represented by InC = InCo - kt. The average concentration of TPHs in the soil was found to be 14.55±0.01 mg/kg. The degradation efficiencies recorded were PBA (86.69 %), PBA + Tween 80 (85.63 %), Tween 80 (76.70 %), and the control (5.40 %). The degradation rates (mg/kg per day) varied from 2.70×10- 2 to 1.30×10-2; 5.00×10-1 to 2.18×10-1; 2.49×10-1 to 1.84×10-1; and 4.67×10-1 to 2.09×10-1 for samples A, B, C, and D respectively. The k values ranged from 2.09 × 10-2 to 2.78 × 10-2, 3.79×10-2 to 5.81×10-2, 2.78×10-2 to 2.09×10-2, and 5.13×10-2 to 3.23×10-2 for samples A, B, C, and D respectively. The degradation efficiency of TPHs was as follows: PBA (86.69 %) > PBA + tween 80 (85.63 %) > tween 80 (76.70 %) > control (5.40 %). The degradation rate of TPHs de
