    摘要:

    采用微波消解預(yù)處理紅葡萄酒，對流動(dòng)注射氫化物原子吸收法（FI—HAAS）測定砷的載氣濃度、流速和載氣酸度，預(yù)還原劑用量及氧化時(shí)間，硼氫化鉀用量等參數(shù)進(jìn)行優(yōu)化，建立流動(dòng)注射氫化物原子吸收檢測紅葡萄酒中砷含量的方法。結(jié)果表明，F(xiàn)I—HAAS檢測紅葡萄酒中砷的方法為：氬氣為載氣，鹽酸為氫化物反應(yīng)的酸介質(zhì)，載氣流速120mL/min，載流酸度1%，檢測使用液為酸度8%的鹽酸，硼氫化鉀質(zhì)量濃度為10mg/mL，氫氧化鈉質(zhì)量分?jǐn)?shù)為0.6%，碘化鉀—抗壞血酸作為預(yù)還原劑，預(yù)還原劑質(zhì)量分?jǐn)?shù)為1%，用量0.5mL，氧化時(shí)間10min。

    Abstract:

    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 120mL/min, current-carrying acidity of 1%, the hydrochloric acid of 8%, borohydride potassium concentration of 10mg/mL, sodium hydroxide concentration of 0.6%, KI—ascorbic acid as the prereductant, concentration of 1%, dosage of 0.5mL, and oxidation time of 10min.
