探讨利用ICP-MS法测定白酒中的锰
摘要
随着人们生活水平的提高,对食品质量和安全的要求越来越高,相应的对食品检验和分析的要求也越来越高。本文利用电感耦合等离子体质谱法测定白酒中锰的回收率,进而判断出电感耦合等离子体质谱法是否适合测定白酒中的锰。
本试验是判断电感耦合等离子体质谱法是否适合测定白酒中的锰。本试验测定的7种白酒分别为:牛栏山二锅头(清香型,酒精度:50%)。富裕老窖(浓香型,酒精度:40%)。西凤酒(凤香型,酒精度:45%)。古井贡(浓香型,酒精度:50%)。龙滨王(兼香型,酒精度:48%)。郎酒(兼香型,酒精度:52%)。泸州福(浓香型,酒精度:52%)。在它们分别加入标量1mg/kg;2mg/kg;4mg/kg时,%-%的范围内,说明电感耦合等离子体质谱法对测定白酒中的锰有很好的效果.

To explore the use of ICP-MS Determination of
manganese in the liquor
Abstract
With the improvement of living standards of food quality and safety have e increasingly demanding, the corresponding test and analysis of food requirements have e more sophisticated, In this paper, the use of inductively coupled plasma mass spectrometry determination of manganese in the recovery rate of liquor, and then determine inductively coupled plasma mass spectrometry determination of the suitability of the manganese in the liquor.
This test is to determine inductively coupled plasma mass spectrometry determination of the suitability of manganese Liquor. The test of the seven kinds of liquor were:牛栏山Erguotou (Fen-flavor, alcohol content: 50%). Laojiao rich (flavor type, alcohol content: 40%). Xifeng Liquor (Feng flavor, alcohol content: 45%).Gujing Gong (flavor type, alcohol content: 50%). Wang Lung-bin (and flavor, alcohol content: 48%).郎酒(and flavor, alcohol content: 52%). Fuk Luzhou (Luzhou-flavor, alcohol content: 52%). They are joined in the scalar 1mg/kg; 2mg/kg; 4mg/kg, the determination of the recovery rate of % -% in the framework of that inductively coupled plasma mass spectrometry for the determination of manganese in the liquor have a good effect。
