The application of spectroscopic techniques in combination with chemometrics for detection adulteration of some herbs and spices
TL;DR: The aim of this article is to review the spectroscopic methods used in testing the authenticity of selected herbs and spices in combination with chemometric techniques, which confirms the origin of the product and distinguishes the adulteration of ingredients in herbal spices available on the food market.
BookDOI
Removal of Organic Pollution in the Water Environment
TL;DR: In this article, the authors present nine peer-review articles presenting research on the determination and removal of environmentally hazardous organic compounds from aqueous samples, which are categorized into three major fields: new approaches to the degradation of water pollutants, new methods of isolation and determination of the emerging organic contaminants (EOCs), and the occurrence of EOCs in the water environment.
