The invention discloses a method for rapidly detecting cadmium ions. The method comprises the following steps: preparing a sample to be detected into a solution to be detected; adding potassium iodide, ascorbic acid, Victoria blue B, sulfuric acid and N-(2-acetamido)-iminodiacetic acid into the solution to be detected, and carrying out a cadmium ion association reaction; after the reaction is finished, observing the color change of the to-be-detected solution, when the to-be-detected solution is blue, indicating that the to-be-detected sample contains the cadmium ions, and when the to-be-detected solution does not have the color change, indicating that the to-be-detected sample does not contain the cadmium ions. The invention provides a method and a kit for rapidly detecting cadmium ions, which can realize rapid and real-time detection of heavy metal cadmium ions. 本发明公开了一种快速检测镉离子的方法，包括以下步骤：将待检测样品配置成待检测溶液；在待检测溶液中加入碘化钾、抗坏血酸、维多利亚蓝B、硫酸和N-(2-乙酰氨基)-亚氨基二醋酸，进行镉离子缔合反应；反应结束后，观察待检测溶液的颜色变化，当待检测溶液呈现蓝色时，则表明待检测样品中含有镉离子，当待检测
