摘要：

In order to demonstrate the possibility of performing direct absorption spectroscopy of Hexavalent Chromium aqueous solutions, absorption measurements were performed at the dual-beam spectrophotometer in the 250-850 nm spectral range, with 10 mm and 100 mm path lengths. Low concentration (26-520 mu g/l) and high concentration (2.6-52 mg/l) solutions were analyzed, showing that it is possible to implement a basic instrumentation for risk condition monitoring and a more advanced instrumentation for quantitative measurements.
