NONAbstract
Vanadium(V) was determined in aqueous solution in three randomly chosen samples from river water Surrounding Al-Jadirya area, via the oxidation of vanadium(V) in acidic medium, creating a coloured species (max 427nm) using continuous flow injection technique. Linear regressicn equation of the from y=a+bx gave linear plot 2-50 g.ml-1 with apercentage linearity of 91.37. while a quadratic equation of the form y=a+bx+cx2 gave a correlation of 0.5-70 g.ml-1. it was found that a quadrate treatment gave much more correlation results.The effect of interfering ions were studied and was noticed that it has little or no effect
