Stable Cl isotopes in subduction-zone pore waters: Implications for fluid-rock reactions and the cycling of chlorine Stable Cl isotope ratios, measured in marine pore waters associated with the Barbados and Nankai subduction zones, extend significantly (to -8‰) the range... B Ransom,AJ Spivack...
(24:1), mixed the samples by inversion, and centrifuged at 16 × gfor 10 min at 4 °C. We again collected the supernatant and precipitated the DNA at 4 °C overnight in polyethylene glycol with 1.6 M sodium chlorine. We centrifuged the samples again at 17 × gfor ...
Investigation of stable chlorine isotopes in geological materials has been hindered by large sample requirements and/or lack of analytical precision. Here we describe precise methods for the extraction, isolation, and isotopic analysis of low levels of chlorine in both silicate and aerosol samples. Our...

These variations are quite small and variations in the Cl isotope compositions of natural samples and natural variations in Br isotope compositions were measured. Basic techniques for measuring chlorine isotopes are chlorine isotope measurements by gas-source ratio mass spectrometry, and Cl isotopes ...
The behaviour of chlorine and bromine isotopes in evaporite deposits differs significantly. We studied the isotope variations of both elements in a fully developed natural salt sequence from Zechstein evaporite deposits (Wuchiapingian, Upper Permian) in the Northern Netherlands. We observed that the ...

The regular addition of hypochlorite or chlorine to drinking water is applied extensively as the most effective means of delivering safe drinkable water due to its powerful anti-microbial functions. It could produce a continuing disinfectant that induces an endurable effect in the distribution system. ...
