Design a flow injection analysis unit for determination of Vanadium (V) by using starch merging zone technique

Abstract

FIA analytical method was a newly designs for determination of V(V) in flow injection technique make deaf in this study and from it selected the best design , depend on the starch –iodine spectrophotometric method, the absorbance intensity was registered in this reaction at 595 nm .The various parameter affecting on the determination have been investigated such as flow rate , reaction coil length, acid volume, sample volume, starch volume , concentration acid ,potassium iodide. Linear calibration graphs were obtained in the range (1-5 ) mg/l, with the detection limit was 0.1 mg/l and correlation coefficient, was (0.995). The desperation coefficient was studied of two concentration (1 mg /l) and (3 mg /l) and found (1.6666) and (1.6240) respectively
