ABSTRACT:
Sequestering compositions are described which utilize two water dispersible polymers, the first having pendant carboxy groups and the second containing hydroxy, amino or imino groups within the polymer. The compositions sequester various metals, are inexpensive to prepare and are easily handled and recovered. A representative embodiment is a mixture of polyacrylic acid and polythyleneimine. Additional chelating agents can be present.
