Inorganic chloramines are commonly used drinking water disinfectants intended to safeguard public health and curb regulated disinfection by-product formation. However, inorganic chloramines themselves produce by-products that are poorly characterized. We report chloronitramide anion (Cl-N-NO) as a previously unidentified end product of inorganic chloramine decomposition.

- - The study focuses on mass transport in passive samplers, specifically through a gel layer made of agarose or agarose cross-linked polyacrylamide (APA), and involves analyzing how substances diffuse through these gels.
- - Standard analysis (SA) using two-compartment diffusion cells showed that while most nitrate tests met the required flux threshold, the diffusion coefficients varied significantly, ranging from 10.1 to 15.8 × 10 cm·s for agarose and 9.5 to 14.7 × 10 cm·s for APA.
- - A new finite difference model (FDM) based on Fick's second law improved the accuracy of diffusion coefficients by tenfold, providing more precise estimates
