摘要：
Pattern recognition of Cu(II), Pb(II), Hg(II) and Cd(II) in waste waters collected from a mining area, was performed using a fast screening method based on a new stochastic sensor. The stochastic sensor is based on physical immobilization of N,N'-ethylenebis[N-[(3-(pyrrole-1-yl)propyl) carbamoyl) methyl]-glycine]) in diamond paste. The limits of determination of the cations were as low as 10 pmol/L [for the assay of Cd(II)], and 100 pmol/L [for the assay of Cu(II), Hg(II), and Pb(II)]. The cations were determined from the waste water samples without any pretreatment of the water samples, within 20 min with recoveries higher than 98.80 %, and low RSD (%) values.
