Journal ArticleDOI
Analytical chemistry in a drop. Solvent extraction in a microdrop.
Hanghui Liu,Purnendu K. Dasgupta +1 more
TL;DR: This unique microextraction system is simple and flexible, permits automated backwashing, consumes only microquantities of organic solvents, and is capable of being coupled with other analytical systems.
Journal ArticleDOI
The origin of naturally occurring perchlorate: the role of atmospheric processes.
Purnendu K. Dasgupta,P. Kalyani Martinelango,W. Andrew Jackson,Todd A. Anderson,Kang Tian,Richard W. Tock,Srinath Rajagopalan +6 more
TL;DR: It is shown that perchlorate is readily formed by a variety of simulated atmospheric processes, and is present in many rain and snow samples, which strongly suggests that some per chlorate is formed in the atmosphere and a naturalperchlorate background of atmospheric origin should exist.
Journal ArticleDOI
Fluorescence Properties of Metal Complexes of 8-Hydroxyquinoline-5-sulfonic Acid and Chromatographic Applications
Krystyna Soroka,Rathnapala S. Vithanage,Denise A. Phillips,Brian Lawrence. Walker,Purnendu K. Dasgupta +4 more
TL;DR: In this paper, the optimum pH for 8-hydroxyquinoline-5-sutfonic acid (HQS) chelates was determined by ligand ionization vs. hydroxo compiex formation.
Journal ArticleDOI
Recent developments in cyanide detection: A review
Junlai Ma,Purnendu K. Dasgupta +1 more
TL;DR: The recent methods cover both established and emerging analytical disciplines and include naked eye visual detection, spectrophotometry/colorimetry, capillary electrophoresis with optical absorbance detection, fluorometry, chemiluminescence, near-infrared cavity ring down spectroscopy, atomic absorption spectrometry, electrochemical methods.
Journal ArticleDOI
Perchlorate and iodide in dairy and breast milk.
Andrea B. Kirk,P. Kalyani Martinelango,Kang Tian,Aniruddha Dutta,Ernest E. Smith,Purnendu K. Dasgupta +5 more
TL;DR: On the basis of limited available data, iodide levels in breast milk may be significantly lower than it was two decades ago and recommended iodine intake by pregnant and lactating women may need to be revised upward.
