Abstract: > 0.99), high accuracy (mean recovery of 96.6-102.9%), and high repeatability (RSD of 2.7-5.2%). Among the three developed methods, UV-Vis is the simplest method whereas HPLC-FL is the most sensitive, with a limit of detection (LOD) of 0.017 wt% for THAM content analyses in AC (compared to UV-Vis with a LOD = 0.59 wt% and HPLC-UV with a LOD = 0.023 wt%). Our assay will serve as a reliable basis for THAM quantification in other solid adsorbents, such as zeolites and porous silica. Additionally, the methods may be adapted for studying solid adsorbents doped with other amino alcohols.
