Özet:

 

The paper describes a novel dip-and-gauge hand-held sensor device for the   rapid, cost-effective, and on-site detection of bisphenol A and arsenic in   drinking water samples. Different working electrode diameters ranging from   1.5 mm to 4 mm were designed and fabricated to construct a new   electrochemical biosensor. The sensor was employed for the   chronoamperometric detection of bisphenol A and voltammetric determination   of arsenic in drinking water samples. Bisphenol A measurements resulted in a   detection limit of 10 ng mL−1−1^{-1} with a linear range of 0-4000 ng   mL−1−1^{-1}. Baby products and bottles have to be completely free of bisphenol   and hence a liquid-phase microextraction method has been developed to reduce   the detection limit further to 0.6 ng mL−1−1^{-1}. Arsenic detection was   investigated in the concentration range of 0.4-250 ng mL−1−1^{-1} with a   detection limit of 1.9 ng mL−1−1^{-1}. The current study showed that the   designed electrode array allows low detection limits (below threshold   levels), although a bare gold surface is used for the study. Hence, together   with a hand-held sensor device that works by simply dipping the sensor chip   into a water container, this cost effective system has the potential to be   used either by household consumers or for on-site inspection purposes.
