Injection reagent

At the proper temperature, the injected reagent reacts selectively in the presence of oxygen to reduce the oxides of nitrogen (NOJ primarily to molecular nitrogen (Nj) and water (FI2O). Figure 17.4 shows the results of pilot-scale tests of the use of urea and ammonia in the SNCR performance. 

The Dual Auger system is an in situ treatment for soils contaminated with volatile organic compounds (VOCs), chlorinated volatile organic compounds (CVOCs), and inorganics. This process uses specialized equipment to mix soil and inject reagents. The system can add nutrients to promote bioremediation, inject steam to volatilize contaminants, install zero-valent iron to promote chemical treatment, or add a pozzolanic slurry to stabilize the contaminants. The injection and mixing process effectively breaks down fluid and soil strata barriers. Mixing also eliminates pockets of contamination that would otherwise remain untreated. 

The silicate in the injected reagent cannot react in the sample stream because the oxalic acid added upstream of the injector destroys the excess molybdate. However, the quenching of the silicate reaction before injection of the reagent is not essential. Automatic refractive index matching also works well in the phosphate analysis (Figures 4 and 5). Any phosphate in the injected reductant is reactive in this case. The additional phosphate will only make the peaks proportionately larger. Standards must be analyzed by the same procedure used for the samples.

On-chip experiments were performed by injecting reagent solutions into the microreactor at flow rates ranging from 100 to 400 nLmin-1 (100 pm by 50 pm channels), and 20 and lOOnLmin 1 (50 pm by 20 pm channels), by means of 100 pL syringes mounted on a CMA/102 microdialysis pump.

Other works were directed toward the use of GUVs, which imitate better cell membranes because of their sizes (10-200 pm) and membrane curvature, and which are easy to manipulate because of their visibility under light microscopes. It is thns possible to select any particular GUV for a given experiment, thus avoiding the rather broad distribution of SUVs and LUVs, which represents a problem if the various sizes of the population do not have identical properties. Moreover, it is possible to directly inject reagents into the vesicles shonld it be necessary, avoiding the low and statistical encapsulation of molecules that govern the experimental work with... 

Relaxation experiments were conducted to determine the location of the separatrix in the [r]-[I03 ] phase plane. The method was similar to that used in the onedimensional system. However, in these experiments the system was perturbed by injecting reagents containing KI, KIO3, and AgN03. In all cases, the volume of the injected reagent (10-70 yl) was insignificant compared to the reactor volume (35.39 ml).
