✦ Synopsis

A study was made of the dissolution of carbon blacks by nitric acid and the yellow color produced. Channel blacks and smaller size furnace blacks dissolve after 3 hr boiling, while larger size furnace blacks and lampblack dissolve after 5 hr boiling. Thermal blacks and acetylene black are only partially attacked after 5 hr boiling. The absorptivity factors for the soluble carbon blacks are tabulated.

Carbon blacks have been featured as model adsorbents in many fundamental investigations of gas adsorption. In particular, the use of graphitized blacks has led to important advances in the understanding of adsorbent-adsorbate interactions and the interpretation of adsorption data. However, in the l
