摘要
在对苯二甲酸(TPA)的生产和再加工过程中,会产生大量废弃物,其中TPA是其主要污染源。从TPA分离提纯、回收再利用的角度出发,介绍了酸析法、盐析法、重结晶法和膜处理法等方法,同时阐述了各自的优缺点及研究现状。最后提出多种方法合理的结合才能达到最佳的效果,指出了TPA回收再利用的发展方向。
In the process of production and reprocessing of terephthalic acid( TPA),a large amount of waste will be produced,in which TPA is the main source of pollution. This paper introduced some effective methods for purification and recycling of TPA,including acid precipitation,salting-out method,recrystallization and membrane treatment. It expounded their advantages,drawbacks and the status of research.Besides,it pointed out that the development direction of the recycling methods of TPA,and put forward that the best effect can be achieved by combining the several methods reasonably.
