Liquid-liquid extraction is a classic sample pretreatment method. This paper introduces a novel extraction technology 4 “sugaring-out” which is based on traditional liquid-liquid extraction and studies its application. Chapter 1: mon sample preparation methods based on liquid-liquid extraction and their applications were reviewed and the principle and conditions of “sugaring-out” were summarized. Chapter 2: With addition of a monomeric sugar or a haride into an acetonitrile-water solution, the acetonitrile would be separated from water to from a new phase. The plexes with Ni2+3Co2+3Cu2+ and Hg2+ were extracted into an acetonitrile phase from aqueous by adding glucose as a phase-separation agent and determined use HPLC. This study establish a new method for detection four metal ions in same time. Chapter 3: A new method for the simultaneous determination of five anthraquinone derivatives in Xiaoerresuqing oral sol
