Improved removal of Trinitrotoluene (TNT) from contaminated soil by inducing aerobic process: kinetic and chemical byproducts
This study describes the biological degradation of TNT by using induced aeration. Three plastic reactors were used. In each reactor 3 kg of soil were used. In order to increase the porosity of the soil, sawdust was added to soil. Textile wastewater treatment plant sludge was also added to soil. TNT at the concentrations of 1000 mg/kg of soil was added thereafter. Rhamnolipid biosurfactant at th...
متن کاملDetermination of Aroclor 1242 Concentration in an Aged Contaminated Soil
Polychlorinated biphenyls (PCBs) are ubiquitous environmental contaminants that have attracted great concern in the past few decades. PCBs were first synthesized in 1864 (WHO, 1993) and widely used in the United States between 1929 until their manufacture was banned in 1977 (Erickson, 1986; Nies and Vogel, 1990). Due to the widespread use of PCBs and improper disposal practices, a significant a...
متن کاملCadmium removal from contaminated soil by tunable biopolymers.
An elastin-like polypeptide (ELP) composed of a polyhistidine tail (ELPH12) was exploited as a tunable, metal-binding biopolymer with high affinity toward cadmium. By taking advantage of the property of ELPH12 to undergo a reversible thermal precipitation, easy recovery of the sequestered cadmium from contaminated water was demonstrated as the result of a simple temperature change. In this stud...
متن کاملBiodegradation of Polychlorinated Biphenyls by and Isolated from Contaminated Soil
Polychlorinated biphenyls (PCBs) cause many significant ecological problems because of their low degradability, high harmfulness, and solid bioaccumulation.Two bacterial strains were isolated from soil that had been polluted with electrical transformer liquid for more than 40 years. The isolates were distinguished as Lysinibacillus macrolides DSM54Tand Bacillus firmus NBRC1530...
متن کاملRecycling of solvent used in a solvent extraction of petroleum hydrocarbons contaminated soil.
The application of water washing technology for recycling an organic composite solvent consisting of hexane and pentane (4:1; TU-A solvent) was investigated for extracting total petroleum hydrocarbons (TPH) from contaminated soil. The effects of water volume, water temperature, washing time and initial concentration of solvent were evaluated using orthogonal experiments followed by single facto...
