Green remediation is essential in the current practice of water resources management. In this study, a series ozone β-cyclodextrin (O3-βCD) inclusion complexes were prepared under selected range different concentrations, β-CD and solution pHs to test their release rates efficiencies treatment total petroleum hydrocarbons (TPH) water. The main objectives study are characterize O3-βCD system, mat...
BACKGROUND In recent years, pollution of soil and groundwater caused by fuel leakage from old underground storage tanks, oil extraction process, refineries, fuel distribution terminals, improper disposal and also spills during transferring has been reported. Diesel fuel has created many problems for water resources. The main objectives of this research were focused on assessing the feasibility ...
The measurement of total oil and grease (TOG) and total petroleum hydrocarbon (TPH) in water and soil samples by means of infrared (IR) absorption is a widely used analytical procedure. It is relatively easy to use, requires little ancillary equipment and is sensitive enough to provide data on TOG and TPH content in the range of permissible concentration levels. Furthermore, IR instrumentation ...
The remediation of petroleum hydrocarbons (TPH) in a contaminated soil by electrokinetic (EK) treatment was studied the laboratory. effects applying constant electrical current on pH, moisture content, conductivity (EC), temperature, and concentrations three fractions TPH (C10–C16, C17–C34 C35–C40) were investigated. experiment run for seven days samples collected at end 7 day period analysis p...
Various inorganic and organic pollutants in industrial soils may adversely affect soil microorganisms and terrestrial ecosystem functioning. The aim of the study was to explore the relationship between the microbial activity, microbial biomass, and functional diversity of soil bacteria and the metals and total petroleum hydrocarbons (TPHs) in the Upper Silesian Industrial Region (Poland). We co...
Bioremediation of diesel oil in soil can occur by natural attenuation, or treated by biostimulation or bioaugmentation. In this study we evaluated all three technologies on the degradation of total petroleum hydrocarbons (TPH) in soil. In addition, the number of diesel-degrading microorganisms present and microbial activity as indexed by the dehydrogenase assay were monitored. Soils contaminate...
In this study, biochar (BC) was prepared from bagasse and then successfully loaded with nanoscale zerovalent iron (nZVI) to produce BC-supported nZVI, termed nZVI@BC. Satisfactory results were obtained using a nZVI@BC-activated persulfate (PS), nZVI@BC/PS, remediate total petroleum hydrocarbons (TPH)-contaminated water. The effects of three influencing factors—the dosage nZVI@BC, DnZVI@BC, the ...
Heavy hydrocarbons (HHCs) in soils impacted by crude oil spills are generally recalcitrant to biodegradation due to their low bioavailability and complex chemical structure. In this study, soils were pretreated with varying concentrations of ultraviolet radiation A (UVA) or ultraviolet radiation C (UVC) activated titanium dioxide (TiO2) (1%–5%) under varying moisture conditions (0%– 300% water ...
This study investigates the concentrations of total petroleum hydrocarbon (TPH) and content (THC) in soil samples from auto-mobile mechanic workshop Ikot Akpaden, Mkpat Enin. Soil were collected triplicate at different points within vicinity Akpaden represented as site A control obtained frontage Chemistry Department, AKSU C. Soxhlet extraction shaking methods used for hydrocarbons respectively...
A laboratory study on the bioremediation of diesel contaminated soil with the earthworm Eudrilus eugeniae (Kingberg) was conducted. 5 ml of diesel was contaminated into soils in replicates and inoculated with E. eugeniae for 90 days. Physicochemical parameters, heavy metals and total petroleum hydrocarbons were analyzed using AAS. BTEX in contaminated soil and tissues of earthworms were determi...
