石墨烯-PET复合纤维的制备及其对水中结晶紫的吸附
Preparation of graphene-polyester composite fiber and its adsorption of crystal violet in water
摘要
Abstract
To solve the problem of environmental pollution of printing and dyeing wastewater, rGO-PET fibers which were made of polyester(PET)fiber as matrix and reduced graphene ox-ide(rGO)as functional coating were prepared by dipping-reduction method.The composite fi-ber was used as a kind of renewable adsorbent to study its adsorption of crystal violet.Results show that the amount of adsorption of crystal violet reaches highest value under the conditions of 30℃,the pH6,the composite dosage of 200mg,and the adsorption time of 60 min.The ad-sorption behavior of the composite fibers on the crystal violet was in accordance with the pseu-do-second order kinetic model,and the maximum theoretical adsorption was 30.528mg/g.Af-ter the adsorption,remove the composite fiber for desorption regeneration which can achieve the recycling of adsorbents.关键词
