摘要
采用微波消解预处理红葡萄酒,对流动注射氢化物原子吸收法(FI-HAAS)测定砷的载气浓度、流速和载气酸度,预还原剂用量及氧化时间,硼氢化钾用量等参数进行优化,建立流动注射氢化物原子吸收检测红葡萄酒中砷含量的方法。结果表明,FI-HAAS检测红葡萄酒中砷的方法为:氩气为载气,盐酸为氢化物反应的酸介质,载气流速120 mL/min,载流酸度1%,检测使用液为酸度8%的盐酸,硼氢化钾质量浓度为10 mg/mL,氢氧化钠质量分数为0.6%,碘化钾-抗坏血酸作为预还原剂,预还原剂质量分数为1%,用量0.5 mL,氧化时间10 min。
Red wine was processed by microwave digestion. Gas concentration, flow, acidity, dosage, potassium borohydride and oxidized time were optimized in the flow injection-hydride atomic absorption （ FI - HAAS） of detecting arsenic. Appropriate measurement parameters were established. FI - HAAS of detecting arsenic in red wine was established. The optimal parameters of arsenic detection of red wine in the FI - HAAS were as follows ： taking argon as carrier gas, hydrochloric acid as the hydride reaction acid medium, the carrier gas velocity of 120 mL/min, current-carrying acidity of 1% , the hydrochloric acid of 8%, borohydride potassium concentration of 10 mg/mL, sodium hydroxide concentration of 0. 6%, KI- ascorbic acid as the prereductant, concentration of 1%, dosage of 0. 5 mL, and oxidation time of 10 min.
