Application

Chlorine gas has been used to generate chlorine atoms via photolysis for molecular halogen photochemical experiments.

It can be used:
  • As a reactant for the extraction of gold from an alluvial material via a pyrometallurgical process.
  • To synthesize carbide-derived carbons (CDC) from zirconium carbide.

Packaging

Supplied in a carbon steel lecture bottle with a CGA180M/CGA110F needle valve installed.

Compatible with the following:
  • Aldrich® lecture-bottle station systems
  • Aldrich® lecture-bottle gas regulators

Disinfectants are commonly applied to control the growth of microorganisms in drinking water distribution systems. However, the effect of disinfection on drinking water microbial community remains poorly understood. The present study investigated the impacts of different disinfectants (chlorine and chloramine)
