摘要
作为重要的化工原料之一,阴离子表面活性剂因其独特的性质,在化工生产中发挥了极大的作用,其可以吸附于表面并改变表面的化学、物理性质,在阴离子进入水面之后可以聚集在一些微小粒子的表面层,并产生一些特殊现象,例如乳化现象,进一步可以阻碍空气中的氧气进入水中,使得水质变得恶化等不良影响,对于水生生物的生存不利。所以,对于阴离子表面活性剂的测定有着极其重要的意义,一个环境中的阴离子表面活性剂可以在一定程度上反映出这个环境的质量高低,但是目前大多数阴离子表面活性剂的测量方法比较繁重且浪费时间和精力。本文主要从流动注射仪的特点、应用现状以及阴离子表面活性剂测定中流动注射仪的应用分析三个方面来进行探究,希望对于利用流动注射仪检测阴离子表面活性剂有一定的帮助。
As one of the important chemical raw materials,anionic surfactants play an important role in chemical production because of their unique properties.They can adsorb on the surface and change the chemical and physical properties of the surface.After the anion enters the water surface,It can be concentrated on the surface layer of some tiny particles,and some special phenomena,such as emulsification,can further hinder the oxygen in the air from entering the water,making the water quality worse and other adverse effects,which are unfavorable for the survival of aquatic organisms. Therefore,the determination of anionic surfactants is of great significance.The anionic surfactant in an environment can reflect the quality of this environment to a certain extent,but most of the anionic surfactants are currently measured in a heavy way.Wasting time and effort.This paper mainly explores the characteristics of the flow injection instrument,the application status and the application analysis of the flow injection instrument in the determination of anionic surfactant.It is hoped that it can be helpful to detect the anionic surfactant by using the flow injection instrument.
