Description:
An experimental protocol for measuring the activated carbon adsorption isotherm was developed and applied to a wide range of organic compounds. Methods for treatment of the isotherm data and a standard format for presentation of results are shown. In the early phase of the study selection of compounds for testing in the experimental program presented a formidable task. Initial selections were based on the following criteria: (1) annual quantity produced, (2) critical concentration required to produce an adverse environmental effect, (3) probability of occurrence in water or wastewater, (4) persistence in the water environment, and (5) solubility. During the course of the study the Occupational Safety and Health Administration's (OSHA) list of regulated carcinogens and the U.S. Environmental Protection Agency's Consent Decree list of priority pollutants were developed. These compounds were added to those previously selected for the experimental phase of the study.
