一、实验方法本实验采用的方法为原子吸收分光光度法.原子吸收分光光度法需要将试样转变成溶液,但是鱼体器官不能直接溶于一般的溶剂中,需要预处理使试样变成溶液形式.首先需对鱼体各部分器官进行消解预处理,采用高压消化法进行,使用微波消解仪,将样品与混合氧化剂置于消化管中,采用单管或多管微波消解方案消化分解,具体操作过程如下:将购得的鳊鱼、鳙、青鱼、鲤称重,分别解剖取得四条鱼的脑、鳃、肝胰脏、肌肉
First, the experimental method The method used in this experiment is atomic absorption spectrophotometry. Atomic absorption spectrophotometry requires the sample into a solution, but the fish organs can not be directly dissolved in the general solvent, the need for pretreatment to make the sample into Solution form.At first, we need digestion pretreatment of various parts of the fish body, using high-pressure digestion method, the use of microwave digestion instrument, the sample and mixed oxidant placed in the digestive tract, single tube or multiple tube digestion microwave digestion solution, The specific operation process is as follows: The purchased bream fish, bream, black carp, carp weighing, were anatomized four fish brain, gill, liver and pancreas, muscle
