Overview
About the Total Chromium Water Analyzer WACR2002.
The WACR2002 total chromium water analyzer is an online analyzer for continuous monitoring of total chromium in water samples. It uses the potassium permanganate oxidation–diphenylcarbazide spectrophotometric method: the sample is first reacted with potassium permanganate to oxidise all Cr3+ to Cr6+, so that the total chromium concentration is measured. Diphenylcarbazide then reacts with the chromium(VI) ions in an acid medium to form an intense pink-violet dye with an absorption maximum at 540 nm. The analyzer measures this absorbance photometrically and compares it with a calibration curve to give the total chromium concentration.
Features
- Imported core components for high reliability and long lifetime in long-term online monitoring
- All wetted parts specially tested for a long service life
- Specially designed flow path to prevent blocking
- Photoelectric measurement with accurate sampling and low sample injection error
- Automatic chromaticity and turbidity compensation for real water samples
- Bubble agitation for thorough mixing of samples and reagents
- Reagent leak alarm with maintenance reminders
- Self-diagnosis function that alarms and displays faults on screen
How it works
- Oxidation: potassium permanganate converts all Cr3+ to Cr6+
- Colour reaction: diphenylcarbazide reacts with Cr(VI) in acid medium to form a pink-violet dye
- Measurement: absorbance at 540 nm compared with a calibration curve
Applications
- Sewage treatment plants
- Industrial production water
- Wastewater treatment processes
- Process monitoring in industrial facilities
