Otimização multivariada e aplicação do sorvente SiO2-Nb2O5 para determinação em linha de Ni(II) em matriz aquosa
In this study a new method for Ni(II) determination in aqueous samples using solid phase extraction coupled to a flow injection system and flame atomic absorption spectrometry was developed. The sorbent used for Ni(II) preconcentration and extraction was silica gel chemically modified with niobium(V...
