General description

Tetrabutyammonium bisulfate (TBAHS) is an ion-pairing reagent. It acts as a catalyst in hydrolysis of aziridines and epoxides and the catalyst can be recycled.

Application

TBAHS was suitable as ion-pairing reagent in determination and separation of thallium using ionic liquid-assisted ion-pairing liquid-liquid microextraction and inductively coupled plasma mass spectrometry. It was suitable as mobile phase component for a HPLC-UV analysis to quantify chondroitin sulfate.

A fast and simple method involving separation and determination of thallium (Tl) species, based on novel ionic liquid-assisted ion pairing dispersive liquid-liquid microextraction (DLLME) method, was developed. Initially, Tl(III) was selectively complexed with chloride ion to form [TlCl(4)](-) chlorocomplex. Subsequently
