Hydroxyphenoxyethyl Ether Dye: Synthesis, Complexation, and Alkali Metal Transport

Abstract

Abstract The synthesis and laser behavior of bis[4‐(2‐benzothiazole‐azo)‐(2‐(o‐hydroxyphenoxy)ethyl)] ether (BTHE) dye has been studied. Its complexation with alkali and alkaline earth metal ions is reported. The extent of complexations, i.e., percentage extraction, extraction constant, distribution ratio, and stability constant were determined and discussed. The liquid membrane transport of sodium and potassium ions with BTHE was also studied.
