Abstract: Intention of this research
was to develop an analytical technique for analysis of alphacypermethrin
(ACYM). It is a pyrethroid insecticide used in agriculture for destroying
harmful insects and for killing malaria vector as a public health program. To
measure residues of the ACYM in some vegetable samples, a novel method is
developed for determination of ACYM. Literatures reveal minimum information
about the spectrophotometric determination of ACYM. When ACYM is brominated, it
forms dibromoalphacypermethrin which reacts with potassium iodide and potassium
iodate in the presence of starch to form blue color dye. The dye show highest
absorbance at λmax = 625 nm. Parameters which effect on the reaction were
studied and conditions were optimized. Linear calibration curve was obtained
from 40 to 120 μg mL-1 ACYM and lower detection limit was 10 μg mL-1. This
method was applied on some vegetables and fruit samples for the determination
of ACYM.
