ABSTRACT:
Poly(2-vinyl pyridine-1-oxide), a nontoxic water-soluble polymer, is useful for chelating heavy metal ions, such as mercury and lead, found as a result of poisoning or environmental contamination. The polymer forms stable metal-chelate complexes and is effective over a wide range of pH values.
