Abstract
The present application discloses a method of binding a metal ion in water. The method comprises contacting the water with a fraction of dissolved organic material (DOM) to form a complex between the DOM fraction and the metal ion; and optionally separating the complex from the water. The present application also discloses a use of DOM for binding a metal ion in water.
Claims19
A method of binding a metal ion in water, the method comprising:
- contacting the water with a fraction of dissolved organic material (DOM) to form a complex between the DOM fraction and the metal ion;
- and
- separating the complex from the water;
- wherein the fraction of DOM is a medium molecular weight organic compound fraction of the DOM (MMW-DOM) having a molecular weight range from 900-1800 Da, and wherein the DOM is from phytoplankton.

- contacting the water with a fraction of dissolved organic material (DOM) to form a complex between the DOM fraction and the metal ion;
- and
- separating the complex from the water,
- wherein the fraction of DOM is a high molecular weight organic compound fraction of the DOM (HMW-DOM) having molecular weights ranging from 1800-3500 Da or a low molecular weight organic compound fraction of the DOM (LMW-DOM) having molecular weights ranging from 150-900 Da,
- wherein the DOM is from phytoplankton, and wherein the metal ion is selected from Hg2+, Cd2+, Zn2+, Co2+, Ni2+ or Pb2+.
