Abstract
The embodiment of the invention discloses a soil heavy metal detector and a detection method thereof. The soil heavy metal detector comprises a sample disc and a detector body, at least one soil sample container is arranged on the sample disc, the detector body comprises a shell, and a detection head, a plane moving device, a tray and a tray sliding rail are arranged in the shell, wherein at leastone side wall of the shell is provided with a detection port for the tray to enter and exit, and the sample disc is fixed on the tray; the tray is fixed to the sliding end of the tray sliding rail, the moving end of the plane moving device is fixedly connected with the detection head, and the moving plane of the detection head is located above the tray. According to the soil heavy metal detectorand the detection method thereof provided by the embodiment of the invention, the detection angle and height are fixed through equipment, so that the detection error caused by arm shaking or environmental change in manual detection is solved, the detection consistency among a plurality of soil samples is realized, the detection method is simplified, the detection efficiency is greatly improved, and the detection cost is reduced. The detection cost is reduced, and the intelligent degree is improved.
Description
technical field [0001] The embodiment of the present invention relates to the technical field of soil detection, in particular to a soil heavy metal detector and a detection method thereof. Background technique [0002] Commonly used detection methods for eight heavy metals in soil (mercury, lead, cadmium, chromium, arsenic, zinc, copper, nickel) include: chemical analysis, electrochemical analysis, optical analysis, chromatography, atomic absorption, chemiluminescence Law. These methods have high detection accuracy and good precision, but the pretreatment steps are cumbersome, time-consuming and expensive. Hand-held X-ray fluorescence spectroscopy (XRF) has good accuracy and precision in detecting eight heavy metals in soil, and is suitable for rapid detection of heavy metals in soil. However, due to factors such as human operation, equipment warm-up time, equipment detection time (120 seconds / soil sample), soil surface leveling, soil density, and soil moisture content, t...
