Dicyandiamide (DCD) is a nitrogenous compound which is generally used as a fertilizer, antimicrobial and nitrogen enrichment agent in soil. Grass and drinking water contamination with DCD may lead to presence of the chemical residues in milk and infant formula. The aim of this study was to investigate a rapid, simple and accurate method for quantitation of DCD in infant formula using electromemebrane extraction with reinforced hallow fiber by graphene oxide (GO-EME). The extraction method was optimized by solvent, graphene oxide concentration, voltage, stirring speed, pH and time parameters. After extraction, DCD was analyzed by HPLC coupled with UV/Vis detector. The analytical method validation parameters including accuracy, precision, LOD and LOQ were determined to ensure the method's validity.The calibration curve with a correlation ratio of 0.999 was obtained. The recoveries were from 78.0% to 80.0%. The LOD and LOQ were 0.04 mg L-1 and 0.1 mg L-1. This study indicates that the graphen oxide-electromembrane extraction is a simple, accurate and rapid method for determination of DCD in infant formula. | ||
