摘要：Monitoring of heavy metals viz., Copper, Nickel, Zinc, Cobalt and Manganese has been done from 25 stations selected along Neeru stream and its tributaries for two years i.e., Jan 2014- Dec 2015. Ultra trace level analysis have been done on Ion Chromatograph by using Metro Sep C4 150 mm column taking 1.75 mM Oxalic acid and 2 mM Ascorbic acid as eluent and 0.15 mM PAR, 0.4 mM ammonia (25%) and 80 mM nitric acid as post column reagent with UV Visible detection. The observed values of Copper, Nickel, Zinc, Cobalt and Manganese at different sampling stations were found to be in the range BDL-0.199, BDL-0.258, 0.001-0.078, BDL-0.074 and BDL-2.050 ppm, respectively. All the analysed metals were found within the permissible limits except Nickel and Manganese at some stations.
