Prinsip dɔ:

Add oxidant, convert three-valent chromium to six-valent chromium, and then add a colour display agent to react with six-valent chromium, creating a violet red complex, to measure its absorption by spectrophotometry, and directly show the total chromium content (mg/L) after calculation by a microcomputer system.
