title: A novel potentiometric sensor for determination of neurotoxin β-N-oxalyl-L-α, β-diaminopropionic acid.
abstract: A novel potentiometric sensor based on ionophore (Cd(NH2CH2CH2OCH2CH2OCH2CH2NH2)Ag3(CN)5) for the determination of β-N-oxalyl-L-α, β-diaminopropionic acid (ODAP) is developed. The ODAP-selective membrane sensor demonstrates high sensitivity and short response time. The detection limit of the ODAP-selective membrane sensor is about 2 × 10(-6) mol L (-1) and the response time is shorter than 6 s. The linear dynamic range of the ODAP-selective membrane sensor is between ODAP concentrations of 1.0 × 10(-2) and 1 × 10(-6) mol L (-1). The ODAP-selective membrane sensor exhibits good operational stability for at least one week in dry conditions at 4-6°C. It has a reproducible and stable response during continuous work for at least 10 h with a relative standard deviation of 0.28% (n = 18).
