On-line preconcentration system for nickel determination in food samples by flame atomic absorption spectrometry
(2001)
An on-line preconcentration system for nickel determination in natural foods has been developed. In it nickel(II) ions are fixed on a minicolumn packed with Amberlite XAD-2 loaded with 2-(2-benzothiazolylazo)-2-p-cresol ...
