Determination of NaFeEDTA by Square Wave Voltammetry
摘要
Abstract
Square wave voltammetry was established to determine sodium iron EDTA（NaFeEDTA）.In the square wave voltammetry,the phosphate buffer solution（pH 3.0） was set as the base solution,scan increment was set for 10 mV,square wave frequency was set at 2.5 kHz,and square wave amplitude was set at 100 mV.The linear range for the determination of NaFeEDTA was 10-200 mg/L with the correlation coefficient of 0.9997.The limit of detection of NaFeEDTA was 4 mg/L.In iron fortified soy sauce and salt samples,the recoveries were（93.5 ± 2.1）% and（96.8 ± 2.8）%.关键词
