    1. Method Overview After the sample is treated, lead ions form a complex with sodium diethyldithiocarbamate (DDTC) under a certain pH condition. The complex is extracted and separated with 4-methyl-2-pentanone (MIBK), then introduced into an atomic absorption spectrometer. After flame atomization, the absorbance is measured at a wavelength of 283.3 nm.
