7.1 Introduction

Chemical processes have impacts on the environment. To reduce their impacts on the environment and human beings, development of safer and cleaner alternatives is encouraged. In this connection, Anastas introduced the concept of green chemistry with 12 principles that provides a roadmap for development and application of safer, more benign chemical processes [1,2]. Thus, the introduction of single-drop microextraction (SDME) in the mid-1990s was an important ...
