Loeffl We report laboratory studies on the 0.8 MeV proton irradiation of ices composed of sulfuric acid (H2SO4), sulfuric acid monohydrate (H2SO4 H2O), and sulfuric acid tetrahydrate (H2SO4 4H2O) between 10 and 180 K.

Hydrofluoric acid.

The Single Absorption – Scrubbing Sulfuric Acid Process

The AE&C single absorption–scrubbing process has long been an alternate to double absorption for the production of sulfuric acid. In recent years regulatory pressure to reduce SO2 emissions from sulfuric acid plants to 1.0-1.25 pounds of SO2 per ton of acid produced (to about 120 PPM) or less coupled with the increased value of energy has enhanced the desirability of the single absorption–scrub...

Etching with Hydrofluoric Acid

Photoresists, wafers, plating solutions, etchants and solvents ... Phone: +49 731 977343 0 www.microchemicals.eu [email protected] Etching of SiO2, Quartz, and Glasses with HF Hydrofluoric acid is the only etchant which attacks amorphous SiO2, quartz, or glasses at significant high etch rate. However, HF is not only a strong corrosive, but also highly toxic towards higher concentrations: ...

Hydrofluoric Acid Exposure

A 21-year-old male was admitted to the emergency department with bleeding skin burns. He had been exposed to 70% hydrofluoric acid (HF) through his nitrile hand gloves during an etching glass procedure at work. He had painful lesions, which included bleeding skin abrasions due to seconddegree burns on the first and second fingertips on the right hand, and white spots on the left first finger, w...
