ERDC/EL TN-14-3 "A Rapid Spectrophotometric Screening Method for 2,4-dinitroanisole in Laboratory Water"
نویسندگان
چکیده
PURPOSE: High performance liquid chromatography (HPLC) and gas chromatography (GC) are most commonly used for the measurement of the insensitive munition constituent 2,4 dinitroanisole (DNAN). These methods require investments in equipment, supplies, labor, and training. A screening method was investigated and validated as a low-cost alternative for ecotoxicology testing to quickly quantify DNAN in solution using commonly available instrumentation. This new method uses a spectrophotometer, measuring absorbance in the ultraviolet range. Simple standard curves are employed to determine concentrations of DNAN. Consistently accurate concentrations were validated by HPLC and GC methods. Additionally, the presence of DNAN breakdown products can be observed.

New explosive compounds that are less sensitive to shock and high temperatures are being tested as replacements for TNT and RDX. Two of these explosives, DNAN (2,4-dinitroanisole) and NTO (3-nitro-1,2,4-triazol-5one), have good detonation characteristics and are the main ingredients in a suite of insensitive munitions (IM) explosives that are being, or soon will be, fielded. Both compounds, how...
متن کاملAerobic biodegradation of 2,4-Dinitroanisole by Nocardioides sp. strain JS1661.
2,4-Dinitroanisole (DNAN) is an insensitive munition ingredient used in explosive formulations as a replacement for 2,4,6-trinitrotoluene (TNT). Little is known about the environmental behavior of DNAN. There are reports of microbial transformation to dead-end products, but no bacteria with complete biodegradation capability have been reported. Nocardioides sp. strain JS1661 was isolated from a...

PURPOSE: Empirical swim speed data are needed to manage invasive bigheaded or “Asian” carps (Figure 1). However, such data are limited within the scientific literature. The large size and active temperament of the carp combined with current legislative restrictions concerning transport, make them difficult to acclimatize and test in traditional laboratory swim tunnels. Biologists from the Engin...

The environmental impacts of energetic compounds can be minimized through the design and selection of new energetic materials with favorable fate properties. Building predictive models to inform this process, however, is difficult because of uncertainties and complexities in some major fate-determining transformation reactions such as the alkaline hydrolysis of energetic nitroaromatic compounds...
