tory technique such as TLC [3 5], HPLC [6-9]
and GC [10,11] or the use of an ion-exchange
resin [12] have been proposed for the determination
of paracetamol. Spectrophotometric determinations
for paracetamol in combination

with oxyphenbutazone and salicylamide
through nitrosation and subsequent chelation
[14,15]. However, the majority of these methods
require lengthy treatments and are not
suitable for routine analysis. Voltamperometric
