2. Application:
Widely used in chromium plating, wood preservation, medicine, catalyst, pigment, oxidizing agent, glass coloring, and mordant of textile etc.
Aldo used as a material producing oxidative catalyst.
3. Notice:
1). Do not store with inflammable substance, reducing agent, organic compounds etc.
2). Avoid moisture, heat and shock during storage and transportation.
3). Also avoid contacting with eyes and skin.
4). Personal protective appliances should be equipped with, such as self-suction respirator, acid –proofing rubber gloves, security coat and boot, chemical-resistant protective glasses.
5). In case of leakage, the polluted area should be quarantined. Entry and exit should be strictly controlled. The leaked material should be gathered, reclaimed or transported and disposed in the waste-disposal station.
