Study on recycling terephthalic acid by activated carbon adsorption in textile wastewater from Island-sea fabric peeling process
Recycling technology for terephthalic acid in textile wastewater was studied. Island-sea fabric peeling process is usually carried out with the use of aqueous sodium hydroxide solution. The research has been made by acidification to recycle terephthalic acid and activated carbon adsorption to improve its quality. The effect of activated carbon quantity and adsorption time on terephthalic acid quality was analyzed. The results show that quantity of activated carbon is 1.0g/L, as well as 30~60min adsorption time can improve the quality of terephthalic acid. The quality factors such as ash content, transmittance at 340nm, acid value and purity are respectively 0. 045 ％, 95％, 648mg KOH/g, more than 96％. The method is very useful in recycling terephthalic acid from textile wastewater and other containers because nowadays TA is widely used in industrial production.
