TL;DR: The method was applied to the determination of ascorbic acid, caffeine and the drug metamizole and was applied in a new approach for determination of organic compounds that can interact with iodine.
Journal ArticleDOI
Determination of iodide based on dynamic gas extraction and colorimetric detection by paper modified with silver triangular nanoplates
Marina O. Gorbunova,Marina O. Gorbunova,Anastasiya A. Baulina,Margarita S. Kulyaginova,Vladimir V. Apyari,Aleksei A. Furletov,Alexey V. Garshev,Stanislava G. Dmitrienko +7 more
TL;DR: In this paper, a new method for sensitive and selective determination of iodide based on dynamic gas extraction with air flow and digital colorimetric detection using paper modified with silver triangular nanoplates (AgTNPs).
Journal ArticleDOI
A dynamic gas extraction-assisted paper-based method for colorimetric determination of bromides

TL;DR: In this article, a new method for selective determination of bromides in natural waters, foodstuffs and pharmaceuticals has been developed, which is based on oxidizing bromide with dichromate, dynamic gas extraction of molecular bromine with an air flow and sensing by paper modified with silver triangular nanoplates as a colorimetric reagent.
Journal ArticleDOI
An improved step-by-step airflow/paper-based colorimetric method for highly selective determination of halides in complex matrices.
