An attempt is made to employ the previously proposed method for preconcentration of nonvolatile impurities as a narrow zone on a TLC plate or on chromatographic paper for extraction of heavy metals from potable water. The method is based on vigorous evaporation of a volatile matrix (water) induced by a stream of hot air. The degree of preconcentration was determined using ICP MS analysis for lead, cobalt, and zinc. The concentrations of impurities increased by a factor of more than 200 over a period of 20–30 min.
