GB/T 41456-2022 《Nanotechnologies—Determination of the concentration of nanometer titanium dioxide airborne dust in workplace—Spectrophotometry method》 Related products

This standard specifies the method of using Spectrophotometric method, spectrophotometry to determine the concentration of nano-titanium dioxide dust in the air of the production environment, including sample collection, processing, testing, data processing and result calculation. This standard is applicable to the use of spectrophotometer to detect the concentration of nano-titanium dioxide dust collected by wet method. Miscellaneous environment The determination of nano-titanium dioxide concentration in air can be referred to. The implementation of the standard provides a reliable basis for the scientific detection of nano-titanium dioxide dust concentration in the production environment.
