Ion Chromatographic Method for Determination of Heavy Metals in Water

Abstract:

Snow (wet deposition) quality in Bucharest city of Romania was studied by investigating the metal ions composition using ion chromatography method. Ten sampling sites were selected and 100 snow samples were collected on in the monitored period. The snow samples were analyzed for the simultaneous determination of transition metals (lead, copper, cadmium, cobalt, zinc, and nickel) in wet depositions. The pH values varied from 5.06 to 7.26, indicating just a few acidic events. The dominance of Zn2+ and Cd2+ ions was observed in this study. Cadmium presented the highest concentration of 671.15 mg/L, followed by lead with 84.34 mg/L, both exceeding the maximum allowed limit. However, it was found that the metal ions composition of snow samples does not present significant seasonal differences. The VWM of the heavy metals decreased in the Zn2+ ] Cd2+ ] Pb2+ ] Cu2+ order. Keywords: heavy metal, meteoric waters, IC, Bucharest
