| 英文摘要 | Based on nanoparticle tracking analysis (NTA) techinque, a dispersion and detection method for itanium dioxide nanoparticles was developed. Influencing parameters on dispersion such as reagent type, ultrasonic method, ultrasonic time, ultrasonic temperature, dispersion reagent concentration and pH value were investigated. The dispersion method had good universality for commercial titanium dioxide nanoparticles. NTA was used to measure particle size and particle number concentration , and the dilution reagent concentration and dilution factor during the detection process were optimized. The results of particle number concentration and size using NTA by the established dispersion method was verified using single particleinductively coupled plasma-mass spectrometry (SP-ICPMS ) and dynamic light scattering (DLS) techniques, and the deviations were +/- 10% and +/- 5%, respectively. By using the developed dispersion and detection methods, the sample could maintain stable up to over a month, which coud be used for the development of basic research and related detection methods. |
