锰是评价酒卫生质量指标之一。目前有条件的单位大都采用原于吸收光谱法测定 ,而大多数基层防疫站都不具备这样先进的仪器 ,仍然采用国标法测定酒中的锰。在测定酒中锰含量时 ,常遇到如下问题 :(1)显色不稳定 ;(2 )空白及零管出现颜色 ,无法比色 ;(3)工作曲线重现性差和回收率 Manganese is one of the indicators to evaluate the quality of wine. At present, most of the qualified units adopt the original method of absorption spectrometry, while most of the grass-roots epidemic prevention stations do not have such advanced equipment and still use the national standard method for the determination of manganese in wine. In the determination of manganese content in wine, often encounter the following problems: (1) color instability; (2) blank and zero tube color, can not be color; (3) poor reproducibility of the working curve and recovery
