摘要

利用二甲基亚砜(DMSO)/1.8-二氮二环[5.4.0]十一碳-7-烯(DBU)/二氧化碳(DMSO/DBU/CO₂)溶剂体系,对纤维素进行荧光功能化改性,制备用于pH和Fe³⁺检测的纤维素基荧光材料。研究结果表明,用该材料制备的薄膜具有较好的pH响应能力,在pH=7～14范围内通过明显的颜色变化对pH进行测定,同时对pH在11～14范围内的识别能力较强,且可重复使用。所制备的纤维素基荧光薄膜还能用于Fe³⁺的检测,检测极限为0.81μmol/L。该材料在环境检测领域具有较大的应用潜力。

Abstract

By using dimethyl sulfoxide (DMSO)/DBU/carbon dioxide(CO₂) solvent system,cellulose was modified by fluorescence functionalization to prepare cellulose based fluorescent material for pH value and Fe³⁺ detection.The film prepared by this cellulose based fluorescent material had good ability to determine pH value in the range of 7～14 by obvious color change.At the same time,it had strong recognition ability in the range of 11～14 of pH value with good reusability.The film of the material can also be used for the detection of Fe³⁺,and the detection limit was 0.81μmol/L.This material had good potential application in the field of environmental detection technology.
