Removing some heavy elements from their chemical solutions by benzimidazole azo reagent

Abstract

Abstract In this articl, we synthezied an azo- benzimidazole reagent to remove the lead and cadmium ions from therir solutions. The yeled of the reagent was high reching 80%. The infrared spectroscopy refres to exit important groups such as hydroxy, N-H, C=N, C=C and azo group which give the color for the regeant. The X-RD spectroscopy indicates crystaline nature of the azo- benzimidazole reagent. The azo- benzimidazole reagent exhibted amisaing ability to remove the cadmium ions in large range of the concentrations and at low concentrations of lead ions with high sensetivity.
