Scientific paper

The rate of erosion of interstellar graphite grains as a result of chemical reaction with H, N, and O is estimated by using the available experimental evidence. It is argued that 'chemical sputtering' yields for interstellar graphite grains will be much less than unity, contrary to earlier estimates by Barlow and Silk (1977). Chemical sputtering of graphite grains in evolving H II regions is found to be unimportant, except in extremely compact (hydrogen densities at least about 100,000 per cu cm) H II regions. Alternative explanations are considered for the apparent weakness of the 2175-A extinction 'bump' in the direction of several early-type stars.
