The invention discloses a method for leaching
heavy metals in
protein foods by using diluted acid and application thereof. The method disclosed by the invention specifically comprises the steps of crushing the
protein foods, adding the diluted acid to leach the
protein foods, then removing insoluble substances, and ultrafiltering and concentrating the protein foods to obtain a solution containingheavy
metal ions. The method disclosed by the invention can be used for leaching heavy
metal ions of
copper, lead and
cadmium in aquatic products and agricultural product
livestock tissues so that the extracting time for leaching the
heavy metals from a sample is shortened and the
pollution brought by the traditional sample pretreatment is also reduced. Compared with a resolution method in a standard in China, the method disclosed by the invention has the
advantage of mild reaction condition; and the obtained leaching solution can be combined with an
enzyme-linked immunosorbent
assay method to realize a field fast detection technology of agricultural products. Therefore, the method for leaching the
heavy metals in the protein foods by using the diluted acid, disclosed by the invention, can be conveniently and rapidly applied as a sample pretreatment technology for detecting the heavy metals by using an
enzyme-linked immunosorbent
assay technology.
