hexavalent chrome

常見例句

Trivalcnt chromium was oxidized to hexavalent chrome by alkaline potassium persulfate under high -temperature. Then total chromium was measured by colorimetry.
在高溫下，用堿性過硫酸鉀溶液將水樣中三價(jià)鉻氧化為六價(jià)鉻，比色測定總鉻。
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.
嗎啉在高溫下將六價(jià)鉻還原為三價(jià)鉻，通過測定三價(jià)鉻離子的吸光度，計(jì)算出鍋爐給水中嗎啉含量。
