“…Rate of Sunlight Degradation of Aqueous Dinitramine. An acetone solution of dinitramine (0.00142 g/cm3) was stirred into 12 1. of water and three 5-ml samples were withdrawn and analyzed (Newsom and Mitchell, 1972) for dinitramine, giving 1.06, 1.01, and 1.12 ppm (average, 1.06 ppm). The solution was then poured into a 63 X 81-cm plastic-lined pan (depth, 2.35 cm) in the direct sun at 1:35 p.m. in Southern California.…”

“…Dinitramine is detected mostly by chromatographic technology, such as gas chromatography, 2,3 electron captured gas chromatography, 4 gas chromatography mass-spectrometry with solid-phase micro extraction, 5 and high-performance liquid chromatography, 6 and computational analysis of the electrostatic potential, 7 has also been reported for the detection of dinitramine. However, seldom electrochemical techniques, which are often simple and less expensive, have been used to determine dinitramine.…”

A novel and sensitive method is described for voltammetric study and determination of dinitramine, commonly used pesticide, based on its electrochemical reduction at a multi-walled carbon nanotube (MWCNT) modified glassy carbon electrode. Cyclic voltammetry (CV) was used to investigate the redox properties of this modified electrode at various solutions pH values and various scan rates. CV studies indicated that the reduction process has an irreversible and diffusion-like behavior in a reduction mechanism with equal number of electrons and protons. The square-wave voltammetry (SWV) was applied as a very sensitive voltammetric detection method for the determination of dinitramine. Under optimal conditions, the proposed method exhibited acceptable analytical performances in terms of linearity (over the concentration range from 4.0 × 10 −8 to 1.4 × 10 −6 and 1.4 × 10 ) and repeatability (RSD = 2.36%, n = 10, for 5.0 × 10 −6 mol L −1 dinitramine). To further validate its possible application, the method was used for the quantification of dinitramine in water samples.

“…The combined extracts were evaporated to dryness using a rotary evaporator. The contents of the flask were dissolved in 5 ml of 95:5 (v:v) hexane:ether, and trans ferred to a florisil column which had been standardized previ ously by the method of Newsom and Mitchell (16). The fraction from florisil clean-up was evaporated to dryness and dissolved in an appropriate volume of distilled benzene.…”

“…Atrazine [2-chloro-4-(ethylamino)-6-(isopropylamino)s-triazine] has been used by producers for many years to pro vide effective quackgrass control in corn (7). However, when applied at rates required for effective quackgrass control, residual atrazine can remain in the soil the following year at concentrations high enough to necessitate growing a tolerant crop for two successive years to avoid crop injury (8,13,16). EPTC (5-cthyl dipropylthiocarbamate) + R -25788 (N,Ndiallyl-2,2-dichloroacetamide), a thiocarbamate herbicide, is used widely to control annual grasses and quackgrass in corn without soil residual problems in soybeans the following year (3,5,6,9).…”

The effects of soil temperature, moisture, and herbicide concentration on the rate of degradation of dinitramine (N4,N4-diethyl-α,α,α-trifluoro-3,5-dinitrotoluene-2,4-diamine) were measured in clay loam and sandy loam in the laboratory. In sandy loam, the rate of degradation increased with increasing temperature. In clay loam, the rate of degradation increased from 10 to 30 C and decreased at 40 C. Soil moisture content influenced the rate of degradation in the following order: 22>11>>2.2% (air-dry) for clay loam and 12.0 = 6.0>>0.5% (air-dry) for sandy loam. First-order half-lives ranged from 3.2 at 30 C to 47 weeks at 10 C in clay loam, and 2.3 at 40 C to 31 weeks at 10 C in sandy loam. Applications in 2 yr did not cause buildup of dinitramine in the field. A mathematical model was used in an attempt to correlate laboratory and field data.
