was dissolved in phosphate buffer
pH 6.0 and transferred to a 100 ml volumetric
flask. The resulting mixture was stirred magneti-cally for 15 min to ensure that terbutaline was
dissolved completely. Appropriate solutions were
prepared by taking suitable aliquots of the clear
supernatant liquor and diluting them with thesame supporting electrolyte. Each solution was
transferred to a voltammetric cell and recorded in
a similar way to the pure drug.
