Analytical Expressions

Mineralogical, bulk and field leachate compositions are used to identify important processes governing the evolution of discharges from a coal spoil heap in County Durham. These processes are incorporated into a numerical one-dimensional advective-kinetic reactive transport model which reproduces field results, including gas compositions, to within an order of magnitude. Variation of input parameters allows the effects of incorrect initial assumptions on elemental profiles and discharge chemistry to be assessed. Analytical expressions for widths and speeds of kinetic reaction fronts are developed and used to predict long-term development of mineralogical distribution within the heap. Results are consistent with observations from the field site. Pyrite oxidation is expected to dominate O2 consumption in spoil heaps on the decadal timescale, although C oxidation may stabilize contaminants in effluents on the centennial scale.

A Current

A newly designed current generator for use with a quarter-wave spark source for a fundamental spectroscopic study of spark discharge chemistry is described. The generator outputs a trapezoidal discharge current waveform whose duration and amplitude are adjustable independently of the source repetition rate up to 5 μsec and 30 A, respectively. A multi-π section LC ladder network and a fast SCR are combined for the new generator to produce the adjustable discharge current waveform, in place of a single RC filter for a conventional current generator. The LC network functions as a current width stretcher and the SCR shapes the pulse into the desired duration by shunt clipping the tail. To evaluate the performance of the new current generator, transient emission waveforms of Cu lines are compared for a trapezoidal current waveform and a simple relaxation discharge waveform with that generated from the conventional generator.

The neutral products resulting from the degradation of aromatic nitrocompounds, following interaction with argon metastables (presumably by Penning ionization), have been studied inside a gas chromatographic system. The simplest but typical example, nitrobenzene, yields benzene and phenol. Product ratios sometimes resemble results of mass spectrometry more than they do data obtained by pyrolysis. The ease of elimination of substituents from monohalogenated nitrobenzenes follows the order I > NO2 > Br > Cl. Ratios of the products resulting from loss of NO (rearrangement) versus loss of NO2 have been measured for a variety of compounds. The leaving NO2 group can be replaced by I if the system is doped with iodine vapour. Reduction of the nitro group and ring closures are observed with some of the more complex substrates, similar to results known from discharge chemistry.
