文摘

The highly sensitive complexation of Cu(II) with Sulfochlorophenol S (SCPS) at pH?4.03 was characterized by the spectral correction technique. This reaction was used to determine the Cu(II) content in various sources by the light-absorption ratio variation approach (LARVA). The limit of detection of Cu(II) was only 1.35?ng/mL, thus facilitating the direct monitoring of natural water. The Cu(II) contents in the Huangpu River, Yangtze River, and Taihu Lake of China were determined with satisfactory results, and the recovery rates of Cu(II) using SCPS were between 94.5 and 102.6?%.
