Type: article
Abstract: Flow injection analysis is can analyze multiple samples, high accuracy, a very fast response time , modern technical devices that are small. This research intended to study the efficiency of ultrasound waves were determined total phenols in wastewater using Folin-Ciocalteu reagent in basic media .The sample or standard phenol solution were injected into a carrier stream to react with Folin-Ciocalteu reagent then expose it to ultrasound waves (46 kHz) which was detected by spectrophotometer at 765 nm. The calibration curve for this method was in the range of (250-2000 ppm ) .The average correlation coefficient was equal to(0.999) . Results of the experiments showed that the ultrasonic method significantly increase peak height after using ultrasound waves . The method was successfully applied for the determination of the total phenols in wastewater
