This study aimed to develop two analytical methods for the determination of Cr6+ from fixed source emissions, such as the molecular absorption spectrophotometric method (UV-VIS) and the graphite furnace atomization absorption spectrometry method (GTAAS). The first stage in the development of analytical methods involves establishing the optimal operating conditions for, taking air samples, treating them for analysis, and proceeding for analysis, followed by validating the method by determining performance parameters. For both methods is highly recommended, the use of isokinetic sampling with a sampling probe by the heated glass, quartz, or PTFE. The limit of detection and the limit of quantification were concluded to be 12.38µg/m3 and 40µg/m3, respectively for the UV-VIS method and the GTAAS method 0.12 µg/m3 and 0.54 µg/m3 respectively.
