Green Sample Preparation Methods
2011Sample preparation is the stage of the analytical process where greenness-related issues can likely play the most important role. With the exception of direct methods for solid sample analysis, for most analytical methods it is necessary to carry out a certain number of operations to make the sample amenable to the instrument.

Natural Sorbents in Green Sample Preparation
2023The evolution of the sample treatment step towards the incorporation of the principles of Green Chemistry inevitably involves the use of materials that are sustainable from an environmental point of view. One of the most important advances in recent years is the use of natural materials as sorbent phases in microextraction processes.

Green Sample Preparation Techniques
2023There is a trend in analytical chemistry towards development of eco-friendly methods of sample preparation without loss of efficiency. This book provides a general, critical, and updated vision of the different green sample preparation approaches that have been developed. These include miniaturisation of the extraction techniques that allow a reduction

Greening sample preparation in inorganic analysis
TrAC Trends in Analytical Chemistry, 2013Sample preparation aims to convert analytes to a more suitably detectable form, to separate them from the sample matrix or to concentrate species for trace analysis. Classical procedures often yield large amounts of toxic waste, but environment-friendly alternatives can be implemented without impairing the analytical performance. Green methods are also

Green Chemistry Considerations for Sample Preparation
2011Green chemistry is the design, development and implementation of chemical products and processes to reduce or eliminate the use and generation of substances hazardous to both human health and/or the environment. Although advances in instrumentation have been made to reduce the amount of organic solvents needed for analytical testing (e.g., reduced ...

Molecularly Imprinted Polymers in Green Sample Preparation
2023The use of molecularly imprinted polymers in sample preparation is nowadays well-established thanks to their ability to provide unprecedented selectivity during extraction and clean-up steps. However, both their synthesis and subsequent use are far from being considered green.

Supramolecular Solvents (SUPRASs) in Green Sample Preparation
2023Supramolecular solvents (SUPRASs) are water-immiscible nanostructured liquids composed of a 3D network of amphiphilic aggregates that maintain their structures via non-covalent interactions. These solvents are prepared from aquo/organic solutions of amphiphiles at concentrations above their critical aggregation concentration.

Green Sample Preparation Applications for Environmental Analysis
2023Environmental contamination is one of the most significant threats to living beings. The main source of contamination is anthropogenic activity, which generates many wastes with a high impact on ecosystems and human life. The monitoring of these toxic substances in the environment (water, soil, sediments, biota, and air) is of special importance to ...

Miniaturization and Automation in Green Sample Preparation
2023Amongst the different steps of any analytical procedure, sample preparation is considered to be one of the most critical. Currently, efforts are centred in the development of miniaturized extraction techniques, which make use of efficient extraction sorbents/solvents and reduce organic solvent and/or energy consumption, following the principles of ...

Deep Eutectic Solvents (DESs) in Green Sample Preparation
2023Current trends in Analytical Chemistry are focused on the development and application of safer and more environmentally friendly procedures that meet the Green Analytical Chemistry principles. In this sense, since their introduction by Abbott et al. in 2003, deep eutectic solvents (DESs) have gained importance as solvents of great utility in extraction
