- W3149743190 abstract "A new method for determination of Cu(II) by DDCT chelating resin preconcentration and thin layer resin phase spectrophotometry was developed. The method has a high sensitivity (e435= 3.6×105L/mol·cm), which is 33 times higher than that of liquid phase spectrophotometry. It has a good selectivity (most coexisting ions could not influence determination) and an ideal precision [30μg Cu(II), n=6, RSD=1.67%]. The content of Cu(II) in water , high purity rare earth and its oxide was determined. The detection limit of Cu(II) is 5.3μg/L , and the linear range is 0~7.2μg/ml. The result is satisfactory." @default.
