Abstract EN
A spectrophotometric flow injection method for the determination of molybdenum (VI) in water sample based on thiocynate complex formation was applied.
A linear line was obtained over the range 0.02- 0.1 μg / ml of Mo (VI).
The RSD of this method was found to be 0.015 %, and the detection limit was found to be 0.01 μg / ml.
The linear curve has a regression coefficient of 0.9997 with sample throughput 78 sample / h.
The influence of interferences on this method was studied.
The molybdenum (VI) concentrations in Shatt Al-Arab River has been measured, at each of the five stations over 12 months during the period from October 2009 to September 2010, monthly variations were recorded.
The results was showed that Mo (VI) concentrations ranged 0.02-0.095 Μg / ml.
where these results indicated that the average of molybdenum (VI) in study area increasing from north (Qarmat Ali) to the south (Fao).The results point clearly that the concentrations of Mo (VI) increasing in December 2009, January 2010 and February 2010, especially in station 2 (Ashar) and station 4 (Seeba) which was 0.085-0.095 μg / ml this can be attributed to put waste from industrial sources ,agricultures and human waste and to the waste from Abadan refinery were the molybdenum is valuable catalyst in the refining of petroleum.
