Effect of the Temperature on chromium precipitation in faucets

Effect of the Temperature on chromium precipitation in faucets

The research was studying the chromium precipitation in faucets which were extracted at ambient temperature of 20 ºC, 40 ºC and 60 ºC by extraction solution, the results showed that in general, the chromium extraction in the faucets increased as the temperature rises. And the chromium extraction in...

After further analysis, the detection showed that Cr VI in chromium precipitation was between 83% and 103% of the total chromium content. This indicated that Cr VI was the main form of chromium in extraction solution, which will be harmful to human health.https://www.e3s-conferences.org/articles/e3sconf/pdf/2021/66/e3sconf_icgec2021_01027.pdf
