DNA was regarded as a naturally occurring biopolymer, and was used to modify polysulfone (PSf) porous microspheres. The DNA-modified microspheres are used to selectively remove endocrine disruptors and heavy metal ions. The DNA-modified PSf microspheres can be prepared using two methods: DNA-blended PSf microspheres and DNA surface modified PSf microspheres. The microspheres, made in the two ways above, are stable in water while they are hydrolyzed under acidic and alkaline conditions. The DNA-modified porous PSf microspheres can effectively remove biphenyl, dibenzofuran and dibenzo-p-dioxin, and can selectively accumulate and remove heavy mental ions.
