Potentiometry using an ion-selective electrode has widely been used for determining fluoride because of its simplicity and rapidity. The concentration of fluoride was determined (Gran's method) in 70 wines from the main wine-producing regions of the Canary Islands. The mean concentration of fluoride in wines from a region with a high concentration of fluoride in drinking waters was significantly (p < 0.05) higher than those mean concentrations obtained in the remaining wines. Non-important differences were found among the types of wine analysed. However, the fluoride concentrations of all the Canarian wines analysed here did not present a risk for the public health.
由于其操作简单且快速,使用离子选择性电极的电位分析法已广泛用于测定氟化物。采用格兰氏法测定了加那利群岛主要葡萄酒产区70种葡萄酒中的氟化物浓度。饮用水中氟化物浓度高的地区所产葡萄酒中的氟化物平均浓度显著高于其他葡萄酒的平均浓度(p < 0.05)。在所分析的葡萄酒类型之间未发现显著差异。然而,这里分析的所有加那利群岛葡萄酒中的氟化物浓度对公众健康均无风险。
