The method is based on preparation of test samples and heavy metals standard solutions, preconditioning them, addition of sodium sulfide solution (for determination of heavy metals) or 1,10-phenanthroline reagent (for determination of iron), dilution with water, mixing well, transfer to two Nessler colour-comparison cylinders, and comparing the colour of both solutions.
