| 主权项 | 1. A method for removing a contaminant from water to be treated comprising (a) contacting the water to be treated with a composition comprising (1) chitosan, wherein the chitosan has a total of 3 to 20 GlcN and/or NAG units and is from 60% to 100% acetylated, and (2) a source of gallium ions to produce a first composition, and wherein the chitosan is in the amount of from 0.05 to 0.2 weight percent of the water to be treated. | ||
