Abstract

The invention discloses a device for measuring heavy metal ions in water. The device comprises a machine box, a box door, a controllable lifting platform, an electro-deposition tank, a polar plate lamping device, a cathode plate, an anode plate, a spectrum detector, a signal transmitting optical fiber, a central control box, a focusing optical system, a lens fixing bracket, a lens regulating device, a wire I, a wire II, a connecting device I and a connecting device II. Firstly, the heavy metal ions in a measured water liquid are enriched on the cathode plate by an electro-deposition technology, and then the cathode plate is measured by adopting an LIBS technology. The device has the advantages of being rapid, high in measurement accuracy and free of complex treatment on a measured water sample.

Description

technical field [0001] The patent of the present invention relates to a device for measuring heavy metal ions in water. The present invention is a device for measuring heavy metal ions in water by combining laser-induced breakdown spectroscopy (LIBS for short) and electrodeposition technology, and especially relates to the field of photoelectric detection instruments A device for measuring heavy metal ions in water. Background technique [0002] At present, the measurement methods used to measure heavy metal ions in water include spectrophotometry, atomic emission spectrometry, atomic absorption spectrometry, and ion selective ionization. However, there are still certain defects in the above method. Spectrophotometry, the interference caused by overlapping spectral lines is serious during measurement, and it must be converted into light-absorbing substances by chemical methods during analysis, which is complicated to operate and easily produces secondary pollution. For ato...
