| 内容記述 | In the present study, we attempted to determine trace arsenic (As) in a dry-type cat food by using a method combining acid circulation decomposition (ACD) and graphite furnace atomic absorption spectrometry (GF-AAS). Since the decomposition container of an ACD device is a semi-sealed type, the presence or absence of volatilization of As during decomposition was confirmed by an addition recovery experiment. Although there was no volatilization during decomposition, it was suggested that As was lost due to bumping during the drying and ashing stages of the GF-AAS apparatus. Loss could be suppressed by changing the temperature program of GF-AAS and slowly drying and ashing. However, the peak appearance time was different between the sample and the standard solution, and it was difficult to quantify by the usual calibration curve method. Therefore, the standard addition method was applied. The appearance time of the peak top was the same at all concentrations, and it was found that the standard addition method is effective when the signal behavior differs between the sample and the standard solution. The determination was tried several times by the standard addition method, but the concentration of As in the sample was below the lower limit of determination (10 ppb) of GF-AAS. It was found that the sample used in the present study contained almost no As and was below the standard value (15 µg/g) of the Pet Food Safety Law. | |||||
