Abstract
Determination total arsenic in food by microwave digestion-hydride generation atomic absorption spectrometry,by which we aims to analysis and discuss the experimental condition and the disturbance situation.The method sensitivity was 0.17 μg /L,and the detection limit was 0.014 μg /L.and values of the relative standard deviation were in range of 4.64% to 9.92%.The recovery of method was founded to be 90.2%~96.5%.
A significance statement is not available in the OpenAlex record.
A contribution statement is not available in the OpenAlex record.
Method details are not available in the OpenAlex metadata.
Findings are not separately available in the OpenAlex metadata.
Limitations are not available in the OpenAlex metadata.
Application details are not available in the OpenAlex metadata.
