前言罗汉果是广西的土特产,罗汉果茶是人们喜爱的饮料之一,它素以润肺,止咳、化痰、清热之功能而驰名中外。罗汉果中总是含有不同的微量重金属元素,当其含量超过一定限量时,就会影响罗汉果的质量及危害人体健康。因此,测定罗汉果中重金属元素的含量,具有重要的意义。罗汉果中重金属含量的测定,目前尚未见报道。罗汉果中铅、镍的含量通常在ppm以下,若用火焰原子吸收法直接测定,样品用量大,共存元素影响测定。目前,有机溶剂萃取 Foreword Lo Han Guo is a native product of Guangxi, Lo Han Guo tea is one of the favorite beverage, which is known for lungs, cough, phlegm, heat and well-known at home and abroad. Mangosteen always contain different trace heavy metal elements, when its content exceeds a certain limit, it will affect the quality of Mangosteen and endanger human health. Therefore, the determination of Mangosteen heavy metal elements, is of great significance. Mangosteen in the determination of heavy metal content, has not been reported. Mangosteen lead, nickel content is usually below ppm, if direct determination by flame atomic absorption spectrometry, the sample dosage, the impact of co-existence of elements. Currently, organic solvent extraction
