Portable water heavy metal analyzer and analytic method thereof

Abstract

The invention discloses a portable water heavy metal analyzer and an analytic method thereof. The analyzer is formed by an electrolytic device and an analyzer main body, wherein the electrolytic device comprises a top cover, an electrode mounting base, a transparent window, a pedestal, a stirring motor, electrodes, a stirring rod and an electrolytic cup; and the analyzer main body comprises an outward interface and an internal circuit module. All the parts of the analyzer harmoniously work under the control of an embedded system to automatically control the enriching, stirring, standing and dissolve-out processes. The analyzer and the analytic method have the advantages of realization of the rapid and accurate detection of the concentrations of heavy metal ions in water, realization of the simultaneous generation of test data and a test place, and avoiding of the generation of artificial recording or statistic errors. The analyzer can be directly used for the emergent and rapid detection of onsite heavy metal pollutions in the field.

Description

technical field [0001] The invention relates to the field of water quality analysis, in particular to a portable water quality heavy metal analyzer and an analysis method thereof. Background technique [0002] The determination of heavy metal element ions in water is an important part of water quality analysis. At present, the technologies used in the monitoring of heavy metal pollution in the water environment mainly include electrochemical analysis, atomic absorption spectroscopy, inductively coupled plasma-atomic emission spectroscopy, and inductively coupled plasma -Mass spectrometer technology and biological monitoring methods. The existing photometric colorimetric detection method has high cost, low detection sensitivity and precision (ppm), complex reagent components, easy to produce secondary pollution, and is greatly interfered by other components; while atomic absorption method and ICP instruments are expensive and bulky Or the operation complexity is high, which ...
