Abstract

For recycling of textile wastes and for environmental preservation, preparation of carbonaceous adsorbent from cotton waste and its application to removal of endocrine-disrupting chemicals in water were investigated. In cotton towel carbonized at 600°C and activated at 850°C with steam, increasing activation time caused a decrease in microporous carbon yield and a linear increase in specific surface area. The specific surface area of microporous carbon with 50% yield was approximately 1000m2/g. Activation with air produced an equal yield of microporous carbon to steam activation, but a smaller mean pore diameter. The amount of 4-nonylphenol adsorbed onto both of the cotton waste-based microporous carbons was very high, even in extremely dilute solution, and efficient removal from aqueous solution was achieved.
