1. A method for removing dissolved contaminants from a solution, the dissolved contaminants including one or more of aluminum, antimony, arsenic in the form of one or both of arsenic(lll) and arsenic(V), barium, cadmium, cesium, chromium, cobalt, copper, gallium, gold, iron, lead, manganese, molybdenum, nickel, platinum, radium, selenium, silver, strontium, tellurium, tin, tungsten, uranium, vanadium, zinc, nitrite, phosphate, sulfite, sulfide, and a low-molecular weight organic arsenic compound, the method comprising the step of contacting a surface-activated titanium oxide in the form of nano-crystalline anatase with a the solution without irradiating the surface-activated titanium oxide, whereby the concentration of at least one of the dissolved contaminants in the solution is reduced to less than about 100 ppm.
