Abstract:The isotope dilution mass spectrometry (IDMS) is a highly efficient method for tackling the ion suppression in complex matrix by ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS), but a lack of commercial internal standards is a limiting factor for these analyses. Herein, an economical and efficient strategy for the synthesis of 13 C 3 -simazine via a three-step procedure was developed. The isotope-labeled internal standard was used for determination of simazine residue in soil samples. The quantitation method has a limit of detection of 0.015 µg/kg and quantitation of 0.08 µg/kg. The inter-day and intra-day precision of the method were below 4.6%. Recovery values were ranged between 92.9% and 99.2%. All the samples obtained from six provinces in China contained from 1 to 62 µg/kg of simazine.

“…Triazine-2,4,6-trione incorporating three 15 N isotopes was produced by condensation of urea containing two 15 N in kerosene and (NH 4 ) 2 SO 4 by heating at high temperature. 34,35 The trimerization of urea takes place at 180 C in kerosene, and produces 15 NH 3 gas, giving triazine-2,4,6-trione incorporating three 15 N stable isotopes in good yield (97%) as a white-brown precipitate. This 15 N-containing compound shows a strong singlet in the 15 Interestingly, the behavior of this coupling reaction differs from that of the 14 N-containing heterocyclic triazine-2,4,6-trione.…”

It has been a spirited, intense, and fascinating journey as I come close to finishing my time as doctoral student at the University of Iowa in Chemical and Biochemical Engineering. First and foremost, I would like to thank my advisor, Dr. Tonya Peeples, for providing me with wisdom and guidance, advice, and unwavering support from the beginning of my time as an incoming graduate student to the very end of my voyage as a PhD graduate in Chemical and Biochemical Engineering. Without her, I would not be where I am today in terms of my personal, professional, and academic development. I would like to thank my family, including my mother Roxanne Delcau, my father Carey Delcau, my brother David Delcau, and my uncle James Roedel for their love, patience, and understanding while I pursue higher education to fulfill my greatest goals. The phone calls, text messages, and road trips to visit me in Iowa City from my loving friends, Ryan Lund and Kevin Robb, have helped me retain my sanity in graduate school. The Chemical and Biochemical Engineering Department and administrative staff, including Sara Hartman and Megan Delaney, for their promptness and aid regarding both personal and professional matters. My current and former graduate lab mates, Richard Gonzales, Felipe Nicolau-Manterola, and Victoria Henry, for their patience in familiarizing me to the graduate work environment and their willingness to help in any aspect of my project and training. A great thanks to the undergraduate research assistants who have helped progress my research, Emily R. Pattee, Sarah Keith, Megan Martin, and Andrea Diaz. The SSTP student, Yiheng Xie, I would like to recognize for performing an incredible amount of research work in a fleeting period.
