A capillary electrophoretic procedure has been developed for quantitative determination of anions in waters. This training session can be completed in 4 hours by undergraduate students. It exemplifies a separation technique, including identification of the various analytes (sulfate, chloride, nitrate) and trace analysis problems in real water samples (river water, drinking water) at the ppm level.
Our Secondary School editors work hard to distill all the JCE materials to produce a fraction of particular interest to high school teachers. We call it CLIC.
In recent years we have worked hard to better match our advertisers with our readers. When shopping for chemistry education materials, visit our advertisers' WWW sites first.
