Millipore, USA). Deionized water was used in the dilution of samples, preparation of reagent blanks, and calibration standards. Nitric acid solution (HNO3) 1% was prepared from 65
The concentrated extracts were subjected to column chromatography for the elimination of certain co-extracted compounds that could possibly bring about interference during instrumental analysis of the target compounds. Each of the water and sediment extracts was made to pass through a chromatographic column...
Before determining the metal content of the sediment, the 100 mL conical flask to be used was pretreated with aqua regia solution, dried, and set aside. Aqua regia is a mixture of concentrated nitric acid and concentrated hydrochloric acid with a volume ratio of 1:3. Then take 0.1 g of ...
