Scope
This document specifies the method for determining the concentration of nano-titanium dioxide dust in the production environment air by spectrophotometry, including sample collection and processing, testing, data processing, and result calculation. This document is applicable to the detection of nano-titanium dioxide dust concentration collected by wet sampling using a spectrophotometer. For the determination of nano-titanium dioxide concentration in other environmental air, this document can be used as a reference.
