hexavalent chrome

基本解釋

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(guò)硫酸鉀溶液將水樣中三價(jià)鉻氧化爲(wèi)六價(jià)鉻，比色測(cè)定縂鉻。
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)鉻還原爲(wèi)三價(jià)鉻，通過(guò)測(cè)定三價(jià)鉻離子的吸光度，計(jì)算出鍋爐給水中嗎啉含量。
