一般描述
Potassium iodate (KIO3) is a colorless solid having monoclinic crystal system. KI solution undergoes anodic oxidation to afford KIO3. KIO3 has strong oxidizing properties. It has been proposed as a promising corrosion inhibitor for carbon steel.
应用
Potassium iodate (KIO3) may be employed in the following studies:
- As primary standard reagent for the volumetric estimations.
- Quantification of hydrolyzable tannins, such as gallotannins and ellagitannins.
- Winkler method for the estimation of dissolved oxygen.
- As a co-inhibitor along with sodium tungstate for prevention of corrosion in carbon steel.

A widely used method for analyzing hydrolyzable tannins afer reaction with KIO(3) has been modified to include a methanolysis step followed by oxidation with KIO(3). In the new method, hydrolyzable tannins (gallotannins and ellagitannins) are reacted at 85 degrees C

Evaluation of contrast enhancement of pulmonary lesions with ground-glass attenuation (GGA) is difficult with conventional techniques but might be possible using contrast-mapping images (CMIs) obtained by dual-energy computed tomography. To address this issue, a phantom study was conducted, and this
