Abstract

The invention discloses a laser-induced breakdown spectroscopy-based hand-held solid waste heavy metal detection probe. The laser-induced breakdown spectroscopy-based hand-held solid waste heavy metal detection probe comprises a housing. A right end of the housing is provided with a laser emission head. A convergent lens and an off-axis parabolic mirror are orderly arranged in a left light path of the laser emission head. The housing at the left side of the convergent lens is provided with a gap. A sample needing to be detected is arranged rightly at the left side of the gap. A plane mirror and a dialyte lens assembly are orderly arranged under the off-axis parabolic mirror. The off-axis parabolic mirror and the plane mirror are coated with broadband dielectric films. The housing under the dialyte lens assembly is provided with an optical fiber end. A doublet and ground glass are orderly arranged at the right side of the plane mirror. The laser-induced breakdown spectroscopy-based hand-held solid waste heavy metal detection probe can detect a detection point which is more than 400mm away from the probe, can avoid direct contact with the solid waste, can protect system and operator safety, has a high integrated level, a small volume and light weight, is in a shape of a pistol, is convenient for operation and carrying, has a low cost and can be realized easily.

Description

technical field [0001] The invention relates to the technical field of environmental optical detection, in particular to a handheld solid waste heavy metal detection probe based on laser-induced breakdown spectroscopy. Background technique [0002] At present, laser-induced breakdown spectroscopy has been widely used in various related fields. It has also been applied to a certain extent in the detection of heavy metals in industrial solid waste. However, the existing heavy metal detection in industrial solid waste based on laser-induced breakdown spectroscopy is still based on on-site sampling and laboratory analysis methods. Regardless of the optical system, spectrometer or computer control system, they are large and heavy. Waste samples can only be used for detection after they have been retrieved from the site and processed. At present, there are few small and light industrial solid waste heavy metal detection systems capable of in-situ detection. Even though opti...
