(2 4 ) ( 2 8 ) deriving the fluid, when detecting, turning on an appropriate voltage on the detecting electrode, and passing through a light source (5 5 ) into the illumination hole (2 2 ), passing through the illumination hole (2; ) With the light-transmissive glass (2 2 4 ), let the light enter the detection space (a), and excite the (four) f-pole (5 〇) to inject the photochemical current of the semiconductor material on the (5 2 ) to amplify the reaction of the current detection. Sensitivity. In addition, the photoelectrochemical detecting device of the present invention can be used by using a reference electrode or an auxiliary electrode connected to the first outflow hole (2 4 ) or the first and seventh outlet holes (26) to increase the operational variability of the detector. . In order to prove the effect of the photoelectrochemical detection method in the present invention, the following is: test pass: using the above-mentioned self-made photoelectrochemical detection to detect the shock, and to measure the bond of the phthalate compound (0HPs), firstly, the needle: the light source The intensity is evaluated for the impact of the entire experiment. Please refer to the fifth figure for the results of Detecting OHPs by ampere voltammetry in a fu system with 12 1251672 and 150W Halogen lamp. The ribs are not applied to the light for 300 seconds. The current signal at μΜ CA is 〇. 33 μΑ. After 300 seconds, the light source is turned on in turn with different intensities (on — a, —b, -c, and max· -d ), and 1 〇〇 CA is also injected under different light source intensities. It is found in the figure that the background photocurrent is larger whenever the light source is stronger. This further proves the mechanism of the photoelectrochemical reaction presumed in the photo, that is, the background photocurrent is determined by the valence band ( After the electrons of VB) are excited, the photoelectrochemical current (/pEc) flowing in the direction of the electrode is caused. At the same time, as the background light _ current increases, the injected CA current signal is also increased and amplified. From the linear regression line (B) of the sixth graph, the trend of change can be more clearly seen. The Halogen lamp can increase the detection current of CA up to 267%, and the increased current is not saturated. It is believed that if a more powerful light source is used, the sensitivity of the detection can be increased. In addition, the present invention has been certified by the American Journal of Analytical Chemistry for correctness and was published in the January 2015 issue of the American Journal of Analytical Chemistry (see attachment for details). As described above, the present invention achieves the advantage of generating a photochemical current increase detecting device by the use of illumination and a semiconductor detecting electrode (5 〇) having photoelectric conversion properties, and on the other hand, the pedestal in the device The pivoting connection with the cover body and the setting of the snap device 彳 to easily open or bond the cover body to replace the test electrode test piece on the base, so that the operation is simple and convenient, so as to simplify the inspection operation. , with considerable progress, practicality and industrial utilization, in line with the invention patent towel requirements 13 1251672 This article proposes invention patent application [simple description of the picture] month (1) pattern part first picture second picture third three The figure view is a perspective exploded view of the present invention. : is a top cross-sectional view of the present invention in a closed state.
