Dechlorination of trichloroethylene formed from 1,1,2,2-tetrachloroethane by dehydrochlorination in Portland cement slurry including Fe(II).

Bahngmi Jung et al.

Chemosphere, 71(4), 726-734 (2007-12-11)

Transformation of 1,1,2,2-tetrachloroethane (1,1,2,2-TeCA) by Fe(II) in 10% cement slurries was characterized using a batch reactor system. 1,1,2,2-TeCA was completely converted to trichloroethylene (TCE) within 1h in all experiments, even in controls with cement that did not include Fe(II). Therefore

Conformational polymorphs of 1,1,2,2-tetrachloroethane: pressure vs. temperature.

Maciej Bujak et al.

Chemical communications (Cambridge, England), 47(31), 8769-8771 (2011-05-28)

Directional Cl···Cl type I and II interactions govern the low-density aggregation of 1,1,2,2-tetrachloroethane molecules in synclinal conformation in the crystalline state at low temperature, whereas the dense molecular packing in high-pressure is achieved for the antiperiplanar conformers and electrostatically less

Simultaneous determination of four synthesized metabolites of mequindox in urine samples using ultrasound-assisted dispersive liquid-liquid microextraction combined with high-performance liquid chromatography.

Jiaheng Zhang et al.

Talanta, 88, 330-337 (2012-01-24)

A novel pretreatment method termed ultrasound-assisted dispersive liquid-liquid microextraction (UADLLME) coupled with high-performance liquid chromatography-ultraviolet detector (HPLC-UV) was applied for the detection of four synthesized metabolites of mequindox in pig urine samples. A total volume of 200 μL of methanol

Structure analysis and performance of a microbial community from a contaminated aquifer involved in the complete reductive dechlorination of 1,1,2,2-tetrachloroethane to ethene.

Simona Rossetti et al.

Biotechnology and bioengineering, 100(2), 240-249 (2008-04-24)

An anaerobic microcosm set up with aquifer material from a 1,1,2,2-tetrachloroethane (TeCA) contaminated site and amended with butyrate showed a complete TeCA dechlorination to ethene. A structure analysis of the microbial community was performed by fluorescence in situ hybridization (FISH)

Dispersive liquid-liquid-liquid microextraction combined with liquid chromatography for the determination of chlorophenoxy acid herbicides in aqueous samples.

Wan-Chun Tsai et al.

Journal of chromatography. A, 1216(45), 7846-7850 (2009-10-07)

A novel sample preparation method "Dispersive liquid-liquid-liquid microextraction" (DLLLME) was developed in this study. DLLLME was combined with liquid chromatography system to determine chlorophenoxy acid herbicide in aqueous samples. DLLLME is a rapid and environmentally friendly sample pretreatment method. In
