常见例句
- Trivalcnt chromium was oxidized to hexavalent chrome by alkaline potassium persulfate under high -temperature. Then total chromium was measured by colorimetry.
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。 - Hexavalent chrome is reduced to trivalent chrome by morpholine under high temperature conditions. Then morpholine content is calculated by detecting the absorbance of trivalent chromic ion.
吗啉在高温下将六价铬还原为三价铬，通过测定三价铬离子的吸光度，计算出锅炉给水中吗啉含量。 返回 hexavalent chrome
