title: [Determination of lead and arsenic contents in amylum by ICP-AES methodology].
abstract: Lead and arsenic contents in amylum were determined by ICP-AES (inductively coupled plasma atomic emission spectroscopy) method with the addition of Ni(NO3)2 as the matrix modifier. Detailed discussion was conducted about the impact of factors such as ashing and automation temperature, ashing method of samples, and matrix modifier on the experimental results. The experimental results showed that ICP-AES method is easy, rapid and exact, its return character is good, and it can be used in the inspection of heavy metals such as lead and arsenic in amylum.
