Development of optical sensor for determination of perchlorate ions
An optical sensor for perchlorate anions (CIO4-) comprising a structure of Cobalt phthalocyanine derivative (Co(II)Pc-PAA) modified glass electrode has been developed. The immobilization of Co(II)Pc-PAA membrane was confirmed by contact angle measurements. The response was determined by the increase in the absorbance signal as a function of exposure to buffer solutions containing different concentrations of CIO4- anions. The optical sensor showed a linear response to CI04- from 10–10M to 10–2 M, with a limit of detection of 4.81 Χ10−10M, one of the lowest achieved up until now. The proposed sensor has demonstrated a good specificity to CIO4- when compared to common interferents anions such as CI−and NO3-. To the best of our knowledge, this is the first optode system for the detection of CIO4-, which provides a promising sensor for the specific and sensitive determination of CIO4- in environmental water samples.
