采用原子吸收分光光度法对脱水前后蔬菜中14种微量元素进行了分析测定、结果表明，脱水加工处理对蔬菜中Se、Co、Ni、Li的损失影响较大，对其他多种微量元素无影响。但加工处理方法不一，微量元素含量不一。采用标准加入法对分析方法进行考察，回收率为963％～106．7％。结果满意。 14 kinds of trace elements in vegetables before and after dehydration were analyzed by atomic absorption spectrophotometry. The results showed that dehydration treatment had a great effect on the loss of Se, Co, Ni and Li in vegetables, but had no effect on other trace elements . However, different processing methods, different levels of trace elements. The method of standard addition was used to analyze the analytical methods, and the recoveries ranged from 963% to 106.7%. Satisfactory results.
