  • Compositions for removing metal ions from aqueous process solutions and methods of use thereof
    Patent number: 7109366
    Abstract: The present invention provides a composition and process using the composition for removing metal ions from aqueous process solutions. These compositions include a non-metallic compound and a suitable carrier. In one embodiment, the non-metallic compound is a thiuram. In another embodiment, the non-metallic compound can further include a dithiocarbamate. These compositions are contacted with the metal ions in the aqueous process solution having a wetting agent to form an organometallic complex precipitate. The precipitate can then be separated from the aqueous solution.

  • Process for reducing the passive layer from the surface of a metal
    Patent number: 6855259
    Abstract: The present invention is directed to a process for reducing the passive layer on a metal. The process includes reacting a treatment composition having a non-metallic compound with metal ions in the passive layer of a metal, thereby forming an organometallic complex precipitate, and removing the organometallic complex precipitate. In one embodiment the non-metallic compound is a thiuram. In another embodiment, the treatment composition further includes a non-metallic compound that is a dithiocarbamate.

  • Compositions for removing metal ions from aqueous process solutions and methods of use thereof
    Patent number: 6818135
    Abstract: The present invention provides a composition and process using the composition for removing metal ions from aqueous process solutions. These compositions include a non-metallic compound entrapped within or supported onto a substrate. In one embodiment, the non-metallic compound is a thiuram. In another embodiment, the compositions further include non-metallic compound that is a dithiocarbamate. These compositions are contacted with the metal ions in the aqueous process solution to form an organometallic complex precipitate.
