Isotopes of chlorine Chlorine (Cl) has isotopes with mass numbers ranging from 32 g mol−1 to 40 g mol−1. There are two principal stable isotopes, 35Cl (75.77%)
CHLORINE in the nature has two stable isotopes, ~(35)Cl and ~(37)Cl. Two methods of determining isotopic ratios of chlorine were once developed. Owen, Kaufmann and Long determined ~(37)Cl/~(35)Cl ratios based on the measurement of CH_3Cl~+ ion produced by ionization of methyl chlorine...
UN-2 If you go swimming without a cap, make sure to wash out the chlorine with a good natural shampoo. 如果你没有戴泳帽去游泳,那么事后一定要用含天然成分的洗发水将氯洗掉。 ParaCrawl Corpus The exterior has a sustainable project, which includes the realization of a natural pool without...
exposed to 0, 0.4, 1.0, or 2.5 ppm chlorine for 2 years, described above, incidence of neoplasia in the nasal passages was not increased by exposure, even though there were exposure-dependent lesions in the nasal tissues (199). Chlorine has not been identified as a carcinogen (IARC 1999)...
like MTBE, GCIRMS has been recognized as a valuable technique in the investigation of the sources and behavior of chlorinated compounds. Most of the work to date with the chlorinated compounds has been related to utilization of the carbon isotopes and, to a lesser extent,hydrogen isotopes. ...
In nature, Cl occurs primarily as the two stable isotopes35Cl (ca. 76%) and37Cl (ca. 24%). In addition, seven radioactive isotopes exist of which six have half-lives of less than 1 h and are of less interest with respect to Cl cycling in the environment. In contrast,36Cl has a...
Stable isotopes of water and 3H–3He were used to delineate recharge patterns and contaminant transport for a granitic regolith aquifer in an industrial complex in Wonju, South Korea, that has historically been contaminated with chlorinated solvents including trichloroethene (TCE) and carbon tetrachlori...
Chlorine has a high electronegativity and a high electron affinity, the latter being even slightly higher than that of fluorine. The affinity of chlorine for hydrogen is so great that the reaction proceeds with explosive violence in light, as in the following equation (where hν is light): In...

But chlorine also has a dark side: In its natural gas form, it is harmful to human health. Chlorine is a respiratory irritant, and inhaling it may cause pulmonary edema — an excessive buildup of fluid in the lungs that can lead to breathing difficulties. The gas can also cause eye and...
