Abstract
  • The combined use of a computer screen and a webcam has been demonstrated in several cases to provide a platform for measuring optical properties of liquid and solid samples. Here the method is utilized to measure the absorbance change in an analytical procedure aimed at determining the amount of hexavalent chromium (Cr(VI)) in water. The method calibrated on standard solutions was tested on-field on naturally contaminated spring waters. Results show a sufficient resolution to measure Cr(VI) concentration down to 5 ppb. World Health Organization recommends a maximum concentration of 0.05 mg/l (50 ppb) for chromium (as hexavalent) in drinking waters. (literal)
