摘　　要：超声波辅助预处理是近年来在样品预处理中受到广泛关注的新技术,与其它预处理方法比较,它在很多方面都显示出极大的优越性。目前,超声波主要用于固体样品的预处理,对于液体样品的预处理,还不被人们熟知。实际上,超声波能量还可改善或加速涉及液体样品的各种分析操作。本文对超声波在液体样品预处理中的应用如显色反应、液-液萃取、均化、乳化和脂化等加以评述。Ultrasound-assisted pretreatment as a novel technique for sample pretreatment,has been paid more attention in recent years.Compared with other pretreatment techniques,it shows many potential advantages in many fields.This paper mainly reviewed the application of ultrasound-assisted pretreatment for liquid sample preparation which is unfamiliar to analysts.The influence of ultrasound energy on the development of chemical reactions,e.g.depolymerization,redox, esterification,alkylation,addition,ethylation of organometallic compounds,complex formation,and that on heterogeneous liquid–liquid processes deserves to be taken into consideration in the analytical laboratory in order to take profit from its versatile effects to improve,accelerate or make possible a given process.
