摘要:

The acid dyes eosin B and tropeolin oo were used for the determination of terfinadine, astemizole and acrivastine in the presence of Mcllvain buffer of a suitable pH. The formed ion-pairs were extracted with chloroform and the absorbances were measured at 530–535 nm and 410 nm in the case of eosin B and tropeolin oo, respectively.
