Electrokinetic Remediation of Uranium Contaminated Soil by Ion Exchange Membranes
Abstract—The contamination of significant quantities of soils and sediments with uranium and other actinide elements as a result of nuclear activity poses many environmental risks. The electrokinetic process is one of the most promising remediation techniques for sludge, sediment, and saturated or unsaturated soils contaminated with heavy metals and radionuclides. However, secondary waste is a ...

متن کاملRhodamine B Hydrazide Revisited: Chemodosimetric Hg-selective Signaling Behavior in Aqueous Environments
The well-known Cu-selective chemodosimetric behavior of rhodamine B hydrazide was successfully switched to selectivity for Hg. The fluorescence signaling is remarkably selective toward Hg ions compared to other common biologically and environmentally important metal ions, including Cu ions. The detection limit was 0.2 μM in an acetate-buffered aqueous 10% methanol solution at pH 5. The OFF-ON t...
متن کاملSensitivity evaluation of rhodamine B hydrazide towards nitric oxide and its application for macrophage cells imaging.
A colorless and non-fluorescent rhodamine derivative, rhodamine B hydrazide (RH), is applied to detect nitric oxide and form fluorescent rhodamine B (RB). The reaction mechanism of RH with NO is proposed in this study. The probe shows good stability over a broad pH range (pH>4). Furthermore, fluorescence intensity of RH displays an excellent linearity to the NO concentration and the detection l...
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...
