Determination of Anilin blue by dispersive liquid liquid micro extraction

In this study a dispersive liquied-liquied micro extraction coupled with vis-us spectrophotometer was used to measure small a mounts of aniline blue . In this way the reactive aliko, aniline blue dye was used as the complexing agent organic and aqueous phases separated after centrifugation and then the amount of aniline blue enrich phase was measured by spectrophotometry . The effective parameters such as type and volume of extraction solvent to efficiency. The sample solution PH , Extraction time and electrolyte type was investigated. the calibration curve in the range of concentrations of 1 to 20 mg per liter (mgL-1) of aniline blue and the detection limit is 0/7 ng mL-1 . the relative standard deviation for 7 times measure aniline blue . At a concentration of 50 ng mL-1 equal to 3/33 respectively. this method has been successfully used to measure aniline blue in water samples Karun river , water and wastewater treatment in Ahvaz and Omidieh were Qazvin industry.
