摘　　要：在高温下,用碱性过硫酸钾溶液将水样中三价铬氧化为六价铬,比色测定总铬。精密度和准确度均与常温消解法一致。Trivalcnt chromium was oxidized to hexavalent chrome by alkaline potassium persulfate under high -temperature. Then total chromium was measured by colorimetry. The accuracy and precision of the improved method were as well as these of the normal temperature digestion.
