Fundamental research has been carried out to use natural fibers, such as cotton, rice husk and straw, which are abundantly available and relatively cheap, to synthesize anion-exchange fibers for the removal of arsenic and fluorine from wastewater.

• 在我们开展的前期研究中，着眼于利用天然纤维素，如棉花、稻草壳、秸秆等来源广泛且经济廉价的原料，合成新型阴离子交换纤维，可望在废水处理中对砷、氟等阴离子起到高效的交换吸附作用。
