摘要
设计了一个在纳米纤维膜中合成MnOx晶体粒子,协同去除颗粒物和甲醛的环境化工原理实验.首先,在静电纺丝液中加入醋酸锰前驱体,采用静电纺丝技术制备出纳米纤维膜.然后,将纳米纤维膜在高温下热解.热解之后,醋酸锰原位分解为MnOx晶体.本实验可以锻炼提高学生的实验动手能力,帮助学生熟悉实验仪器.同时,可以使学生更好地了解膜分离和静电纺丝技术相关知识.
Abstract
An Environmentally chemical engineering principle experiment was designed to synthesize MnOx crystal particles in nanofiber membranes.Firstly,manganese acetate precursor was added into Electrospinning solution,and nanofiber membrane was prepared by Electrospinning technology.Then,the nanofiber membrane was pyrolysed at high temperature.After pyrolysis,manganese acetate decomposed in situ into MnOx crystals.This experiment can exercise and improve students'hands-on experimental skills,helping them become familiar with experimental instruments.At the same time,they can better understand the knowledge of membrane separation and Electrospinning technology.
