C02F 1/28

US Classification:

524440, 525451, 524608, 524439, 524606, 210688, 210663, 423210

Abstract:

A polymer, a composition, and uses for either are disclosed. The polymer is derived from at least two monomers: acrylic-x and an alkylamine, and has attached to the polymer backbone a functional group capable of scavenging at least one metal. The polymer has a polymer backbone with a fluorescing quantity of conjugated double bonds, thereby providing a method for controlling metal scavenging via fluorescence. These polymers have many uses in various media, including wastewater systems.

International Classification:

C02F 1/42
B01J 20/02

Abstract:

Methods of modification of zero-valent iron (ZVI) to improve its performance in removing contaminants from a discharge stream. In some aspects, the methods include contacting ZVI-impregnated disks with solutions containing metal cations such as Ni, Cu, Fe, or Pd. In some aspects, a wastewater stream is treated with a metal cation solution, then passed over ZVI. Compositions for treating wastewater include ZVI that is modified with a metal cation solution.
