• Evaluation of the Greenness of Analytical Procedures

  Publikacja

  • M. Bystrzanowska
  • J. Namieśnik
  • M. Tobiszewski

  - Rok 2020

  This contributions introduces the need to develop the methods to evaluate analytical procedures in the light of green analytical chemistry. Green chemistry metrics are not applicable in analytical chemistry because they refer to the mass of product and no product with mass is generated during analytical determination. Analytical greenness evaluations are based on scoring - such as NEMI or Eco-scale or comparative analysis as it...

  • J. Namieśnik

  - TRAC-TRENDS IN ANALYTICAL CHEMISTRY - Rok 2012

  We propose the analytical eco-scale as a novel comprehensive approach to evaluating the greenness of analytical methodology. It is based on assigning penalty points to parameters of an analytical process that are not in agreement with the ideal green analysis. This approach compares different parameters and different steps of the analytical process. Traditional green chemistry metrics 9e.g. Atom Economy, E-factor and Reaction Mass...

  - TALANTA.The International Journal of Pure and Applied Analytical Chemistry - Rok 2012

  Because of their specific physical and chemical properties (amphiphilicity, solubility in polar and nonpolar liquids, ability to form micelles, adsorption at phase boundaries, low toxicity) surfactants (surface-active compounds) are widely applied in industry and in the household. As their applications are on a very large scale, it has become necessary to acquire a more detailed understanding of their environmental fate.In the...
