Abstract

This study determines ash, K, Ca, Na, Mg, Fe, Cu, Pb, and Zn content in musts and wines of the DOC Tacoronte-Acentejo (Tenerife, Canary Islands) from two consecutive harvests. Samples were treated with HNO3 and H2O2. Na and K were determined by flame photometry and the remaining metals by air/acetilene flame atomic absorption spectrophotometry. Significant differences were observed in Na, Ca and Mg contents between both harvests, possibly due to climate conditions.

摘要

本研究测定了来自特内里费岛（加那利群岛）DOC Tacoronte - Acentejo连续两个收获季的葡萄汁和葡萄酒中的灰分、钾、钙、钠、镁、铁、铜、铅和锌含量。样品用硝酸和过氧化氢处理。钠和钾通过火焰光度法测定，其余金属通过空气/乙炔火焰原子吸收分光光度法测定。两个收获季之间在钠、钙和镁含量上观察到显著差异，这可能是由于气候条件所致。
