title: [Determination of stability constant of glutamate zinc by indirect determination of FAAS with ZnS].
abstract: Based on indirect determination of glutamic acid by flame atomic absorption spectrometry with ZnS and the complexing action mechanism, the determination of stability constant of glutamate zinc was studied. Under the selected condition of pH 9.0, the stability constant of glutamate zinc is between 3.3 x 10(20) and 1.4 x 10(21), the average value is betaw = 1.03 x 10(21), and log betaw = 21.013.
