This review summarizes the current state of green analytical chemistry with special emphasis on environment friendly sample preparation techniques. Green analytical chemistry is a part of the sustainable development concept. Miniaturization of analytical devices and shortening the time elapsing between performing analysis and obtaining reliable analytical results are important aspects of green analytical chemistry. Some of the principles of green chemistry such as prevention of waste generation and design energy efficiency to minimize the potential of chemical accidents. Some naturally green or possibly green analytical techniques are also discussed. Presently, spectroscopic methods dominate the area of green analytical chemistry. This makes an analytical laboratory comparable with the fine chemicals or pharmaceutical industries. Solvent less extraction techniques, the application of alternative solvents and assisted extractions are considered to be the main approaches complying with green analytical chemistry principles. The purpose of this report is to arouse more attention to green analytical chemistry to serve the sustainable development of the modern society.
