Barium chlorine

During the troubles in Northern Ireland only indoor-type fireworks could be purchased without a special license. Analysis of particles originating from the use of indoor-type fireworks showed only a few spherical particles the majority was large irregularly shaped flakes. The elements aluminum, barium, chlorine, chromium, iron, potassium, sulfur, and antimony were detected, all of which were at a major level.

The strontium and barium analyses of sea water are reported. Concentrations of these elements in sea water were simultaneously determined by a combination of ion exchange concentration and flame photometry to ascertain more precisely strontium/chlorinity and barium/chlorinity ratios and to investigate the magnitude and nature of the strontium/chlorinity ratio variation if it was found. The results of the analyses of several ocean stations presented indicate that there is a small (ca. 3%) but statistically significant variation in the strontium/chlorinity ratio with respect to depth in sea water. An indication of a possible variation in the absolute amounts of strontium in sea water with the geographical location has also been observed. The barium/chlorinity ratio variation with respect to depth was found to be much larger (ca. 90%) than that of strontium. 

There have been several reports on studies of the determinations of the strontium (2, 4, 5, 6, 8, JO, 12,14,17, 19, 20, 23) and barium (7, 8, 9, 11,22) concentrations of sea >vater and the resulting calculated strontium/ chlorinity and barium/chlorinity ratios. The samples analyzed were from numerous geographical locations and depths, with the pretreatment and methods of analysis of the samples not always being similar. The majority of the reports concerning strontium distributions indicate a constant strontium/chlorinity ratio with respect to depth and geographical location within the limits of experimental error of the methods used. The range of the values for this ratio which have been reported most recently... 

The results of the studies on the barium concentration of sea water have conversely, clearly demonstrated the existence of a variation in the barium/chlorinity ratio. Prior to 1966 very few analyses of the barium concentration of sea water had been reported. Turekian and Johnson (22) have recently reported the results of over 250 determinations of the barium concentration of sea water. The average values reported for the barium content of 24 samples from the Atlantic Ocean, the area which is of concern in the present investigation, range from 9 to 30 p.p.b. 

The present authors have recently described (I, 2) the development of an accurate and precise analytical method using ion-exchange concentration and flame photometry to measure the strontium and barium concentration of sea water from the same sample. Initial analyses indicated that there is possibly a small, but significant, variation in the strontium/ chlorinity ratio with respect to depth (2, 3). The results of the analyses for barium indicated that, as expected, the variation in the barium/ chlorinity ratio is much larger. This communication reports the results of the analyses of samples from several ocean stations for strontium and barium. 

The stations at 00°02 S 35WW and (WWN 47°00 W generally show higher and more variable barium/chlorinity ratios with the more northern station having the higher values. The profile at 00°02 S has the maximum value for the ratio at the surface, the only location at which...

Chlorine, bromine and iodine form halic(V) acids but only iodic(V) acid, HIO3, can be isolated. Solutions of the chloric) V) and bromic) V) acids can be prepared by the addition of dilute sulphuric acid to barium chlorate(V) and bromate(V) respectively, and then filtering (cf. the preparation of hydrogen peroxide). These two acids can also be prepared by decomposing the corresponding halic(I) acids, but in this case the halide ion is also present in the solution.

Stabilization Mechanism. Zinc and cadmium salts react with defect sites on PVC to displace the labHe chloride atoms (32). This reaction ultimately leads to the formation of the respective chloride salts which can be very damaging to the polymer. The role of the calcium and/or barium carboxylate is to react with the newly formed zinc—chlorine or cadmium—chlorine bonds by exchanging ligands (33). In effect, this regenerates the active zinc or cadmium stabilizer and delays the formation of significant concentrations of strong Lewis acids. 

Materials. Beside inorganic materials (eg, barium chloride/fluoride crystals, doped with 0.05% samarium), transparent thermoplasts are preferred for the PHB technique, eg, poly (methyl methacrylate) (PMAIA), polycarbonate, and polybutyral doped with small amounts of suitable organic dyes, organic pigments like phthalocyanines, 9-arninoacridine, 1,4-dihydroxyanthraquinone [81-64-1] (quinizarin) (1), and 2,3-dihydroporphyrin (chlorin) (2). 

Laser isotope separation techniques have been demonstrated for many elements, including hydrogen, boron, carbon, nitrogen, oxygen, sHicon, sulfur, chlorine, titanium, selenium, bromine, molybdenum, barium, osmium, mercury, and some of the rare-earth elements. The most significant separation involves uranium, separating uranium-235 [15117-96-1], from uranium-238 [7440-61-1], (see Uranium and uranium compounds). The... 

Many of the metal chlorites are not particularly stable and will explode or detonate when stmck or heated. These include the salts of Hg", Tl", Pb ", Cu", and Ag". Extremely fast decomposition with high heat evolution has been noted for barium chlorite [14674-74-9] Ba(Cl02)2, at 190°C, silver chlorite [7783-91-7] AgC102, at 120°C, and lead chlorite [13453-57-17, at 103°C (109). Sodium chlorite can be oxidized by ozone to form chlorine dioxide under acidic conditions (110) ...

In a reactor at low pressure (0.2-0.3 MPa) and moderate temperature (375 °C) the PVC is chemically and thermally degraded. A particular feature of the process is that the chlorine in the PVC reacts in part with the fillers in PVC and is neutralised with the formation of CaCl2. In similar vein, metal stabilisers in PVC are converted into the respective metal chlorides (lead, cadmium, zinc and/or barium). At current PVC waste compositions these chlorides consist of 60% lead which can be purified and re-used. The reaction in the end results in the following solid, liquid and gaseous products.
