AI Article Synopsis
- A new method using cellulose pellets with potassium titanium oxide oxalate (PTO Pellets) can determine hydrogen peroxide (HO) vapor pressures in powder systems.
- The color change of these pellets after exposure to HO vapor allows for quantitative analysis, comparing their reactions in both liquid and solid forms.
- This technique offers simple fabrication of highly sensitive probe particles, detecting HO at levels as low as 0.190 ppm.
Article Abstract
An image-based method for determining HO vapor pressures in powder systems was developed based on cellulose pellets loaded with potassium titanium oxide oxalate (PTO Pellets) as probe particles. Solid titanyl salts change color after exposure to hydrogen peroxide vapor and the quantitative response of PTO pellets to HO has been established by comparing reactions with HO in liquid and solid states. Analysis of pictures of the color changes of PTO Pellets mixed into powders can be used to monitor the presence of ppm levels of HO vapor inside powder systems such as bleach containing dry detergent powders.•HO vapor quantification in dry systems with titanyl loaded cellulose particles.•Simple fabrication of HO probe particles.•High sensitivity with LOD 0.190 ppm HO
