[Improvement of 2-mercaptoimidazoline analysis in rubber products containing chlorine].
An improved analysis method for 2-mercaptoimidazoline in rubber products containing chlorine was developed. 2-Mercaptoimidazoline (20 µg/mL) is detected by means of TLC with two developing solvents in the official method. But, this method is not quantitative. Instead, we employed HPLC using water-methanol (9 : 1) as the mobile phase. This procedure decreased interfering peaks, and the quantitat...
متن کاملReaction products of chlorine dioxide.
Inspection of the available literature reveals that a detailed investigation of the aqueous organic chemistry of chlorine dioxide and systematic identification of products formed during water disinfection has not been considered. This must be done before an informed assessment can be made of the relative safety of using chlorine dioxide as a disinfectant alternative to chlorine. Although trihal...

متن کاملThe Chlorine Isotope Composition of the Moon
Introduction: Sharp et al. [1] determined that the δCl value of carbonaceous chondrites, mantle samples and crustal materials are all close to 0‰ (Fig. 1). There are some small but significant variations. For example, sodalite inclusions in CAIs from Allende are distinctly negative. These samples were measured with an ion probe, as opposed to gas source mass spectrometry, nevertheless they were...
