Abstract
THE existing contradictory results on the photoelectric effect of carbon can be explained by means of the quantity and quality of the gases absorbed by the carbon. The influences of ammonia, hydrogen, air, and carbon dioxide were investigated. The most consistent results were obtained from carbonised bamboo and hydrogen. Saturation curves showed ammonia to be the most active, and carbon dioxide the least. Distribution of velocity curves were obtained for bamboo and hydrogen. The maximum initial velocity was found to be independent of the quantity of hydrogen absorbed, while the maximum current was proportional to the quantity of gas absorbed.
