Abstract
The sorption behavior of the pyrolysis products (pyropolymers) of organic polymers was investigated. The results indicate that the pyropolymers of poly (vinyl chloride) exhibit selective adsorption towards the herbicide 2-sec-butyl-4,6-dinitrophenol but none to 2,4-dichlorophenoxyacetic acid. The initial rate of adsorption during the first hour is almost twice that of activated carbon with a total uptake of approximately 30% depending on the preparative conditions of the pyropolymers. However, unlike activated carbon, the pyropolymers of poly (vinyl chloride) slowly releases the adsorbate.
