In this work, the complexation reactions of Pb(II) with Herring sperm DNA were studied. The DNA solution prepared was tested for hyperchromicity and then, Pb(II) ions were added to form 0.0, 0.33, 0.5, 1.0, 1.5, and 2.0 Pb(11)/DNA mole ratio solutions. Changes in UV-Vis heating and reheating absorba...
