Abstract

The invention relates to a heavy metal analysis detection device, particularly relates to a portable trace heavy metal ion concentration detecting pen, and aims to solve the problem that an existing detecting device is not suitable for field quick detection due to large size, expensive instrument, high operation cost, complicated detection steps and carrying inconvenience. The detecting pen comprises a hollow penholder, wherein an electrode assembly, a spring, a button and a stripping voltammetry-based detection circuit are arranged in the hollow penholder from bottom to top sequentially; the spring sleeves the electrode body of the electrode assembly, and the lower end of the spring is clamped on an annular spring bulge on the inner wall of the hollow penholder; the button is formed by an annulus body and a stirring handle fixed on the outer ring of the annulus body; the annulus body of the button is fixed at the upper end of the electrode body of the electrode assembly in a sleeving manner; and the stirring handle of the button extends out of an L-shaped hole in the hollow penholder. The portable trace heavy metal ion concentration detecting pen is small and portable, is quick and safe to operate, has the advantage of short detection time, high accuracy and high integrality, and is especially applicable to field detection.

Description

technical field [0001] The invention relates to a heavy metal analysis and detection device, in particular to a portable trace heavy metal ion concentration detection pen. Background technique [0002] With the rapid development of industry, agriculture, and transportation, the mining, smelting, processing, and commercial manufacturing activities of heavy metals are increasing, which makes heavy metal ions, such as lead, mercury, cadmium, and chromium, enter water, soil, etc. The environment seriously endangers the survival of human beings and all kinds of creatures. The wide distribution and non-degradability of heavy metal ions make it easy to accumulate in the body after absorption by the human body. Even if the concentration is on the order of 10-6, the harm to the human body is very obvious. At present, heavy metal poisoning is one of the important public health problems in developing countries, especially for children, and heavy metal poisoning will affect their whole...
