Device for Detection of heavy metals: Pb2 +, Cd2 + and Hg2 +

摘要

This device is connected with the branch of Analytical Chemistry for the Detection, Separation and concentration, removal of trace metals: Pb2 +,Cd2 + and HG 2 + present in the waters of any kind.Consists of: a bottle of 1 l capacity, a Glass column Chromatography with Flow Regulator and packed with 1 g of adsorbent trieptu00edloctodecu00edlamonio iodide in silica,A Collector, Confetti with 0.5 g of 5% metiltimolazul Indicator and 1.66 g of Potassium iodide with a container 10 ml Volumetric.By the Glass column packed with the adsorbent is 1 l of water, to analyze, to which has been added Potassium iodide, regulating the flow of Drip to 1 ml / min.Once filtered Sample, add 10 ml of indicator to the adsorbent.Comparing the observed colour with the colour scale and learn semiquantitatively the metal concentration present in the sample, in a range of concentration of 100 mg to 50 ng.
