Abstract

The invention relates to a cellulose-based imprinted adsorbing agent which has the high-selectivity adsorption capacity on a phenolic pollutant in a solution and a preparation method of the cellulose-based imprinted adsorbing agent.The cellulose-based imprinted adsorbing agent is synthesized by adopting an active free radical polymerization method.The method comprises the steps that smashed cellulose is dissolved in a cellulose dissolving agent under the assistance of ultrasonic waves or microwaves, and then homogeneous-phase esterifying modification is performed on the cellulose to prepare a cellulose macroinitiator; the phenolic pollutant is taken as a template, a functional monomer, a hole generating agent, a catalyst and a coordination agent react under a certain condition, and after reacting is finished, template molecules are washed off to obtain the cellulose-based imprinted adsorbing agent for the phenolic pollutant.A static adsorption test is used for studying the adsorption balance, kinetics and selectivity recognition properties of the imprinted adsorbing agent.A result shows that the obtained cellulose-based imprinted adsorbing agent has the quick adsorption kinetics property and the superior phenolic pollutant molecule recognition property on the phenolic pollutant.

Description

technical field

[0001] The invention relates to the fields of fine chemicals, environment-friendly materials and adsorbents, in particular to a cellulose-based phenolic compound molecularly imprinted adsorbent and a preparation method thereof. Background technique

[0002] As important chemical raw materials, phenolic compounds are widely used in many industries such as petrochemical, printing and dyeing, pesticides and organic synthetic materials. into the natural water environment [1]. In recent years, the impact of these compounds on the environment has attracted widespread attention. Among the 129 priority pollutants issued by the US Environmental Protection Agency (EPA), there are 11 kinds of phenolic compounds [2]. Cresol, 2, 4-dichlorophenol, 2, 4, 6-trichlorophenol, pentachlorophenol, 4-nitrophenol, which are six kinds of phenolic pollutants, are the key treatment targets[3,4 ], so the treatment of phenolic wastewater has attracted great attention from government a...
