Optical Sensor for the Determination of Pb2+ Based On Immobilization of Dithizone onto Chitosan-Silica Membrane
ABSTRACT: Optical sensor based
on incorporation of dithizone and chitosan-silica for the determination of lead
(II) ion has been conducted. The optical sensor was made by composite of
chitosan and silica in the ratio 2:1. Sol gel technique was chosen to make the
membrane because it has some advantages such as its low temperature and
chemical reactivity. The sensor has a good selectivity at pH 5 with response
times at ± 180 s. Linearity responses was obtained with concentration range
from 0.2 to 1.1 ppm with r2 = 0.9921. Average of %RSD on precision and accuracy
(%PK) test were 1.46 and 100.96%, respectively. Limit of detection (LOD) and
limit of quantification (LOQ) were 0.11 ppm and 0.37 ppm, respectively
