Abstract
The invention relates to a heavy-metal chromium form separating method, which firstly utilizes dolomite as adsorption materials and is used for separation of Cr (VI) and Cr (III) in the natural water environment. According to indication of a series of tests, adsorption rate of the dolomite (80-100 meshes) in the natural water body to the Cr (III) is larger than 95% and is lower than 5% to the Cr (VI). Adsorbent used in the heavy-metal chromium form separating method is natural minerals, low in cost and convenient to be obtained, and the heavy-metal chromium form separating method is simple, fast and evident in separation effect. Accordingly, the heavy-metal chromium form separating method can be used for separating forms of Cr (III) and Cr (VI) in the water body.
