Aluminum oxide | Al2O3 - PubChem

The concentrations of aluminum in tissues of New Zealand rabbits exposed to /aluminum oxide/ dust at a concentration of 0.56 mg Al/cu m for 5 months (8 hr/day, 5 days/week) were determined. The amount of aluminum in the brains of the animals was nearly two and a half times as high as that of the control animals. The concentrations in other tissues were only slightly increased.

Calcium Oxide Based Sorbents for Capture of Carbon …

2018-4-16 · Calcium oxide is a promising sorbent for the capture of carbon dioxide. In this work, CaO sorbents were prepared using different precursors, including Ca(NO3)2·4H2O, CaO, Ca(OH)2, CaCO3, and Ca(CH3COO)2·H2O. Of these, the sorbent prepared from calcium acetate (CaAc2−CaO) resulted in the best uptake characteristics for CO2. This sorbent had a higher BET surface area and larger pore …
