Abstract

The invention discloses a method for dispelling ultraviolet ray with controllable wavelength. According to the method, one or more of a UV-A lamp tube circuit, a UV-B lamp tube circuit and a UV-C lamp tube circuit are connected by virtue of an ultraviolet lamp selector connected with a wavelength-controllable ultraviolet lamp group; the wavelength-controllable ultraviolet lamp group is arranged on a rotary base; the rotating speed of the rotary base is adjusted by rotating a controller, so that the wavelength-controllable ultraviolet lamp group is rotated to perform ultraviolet dispelling on samples in sample tubes on the periphery of the ultraviolet lamp group. Compared with a method for dispelling an ultraviolet lamp with single wavelength, the method has the advantages that wavelength controllability can be realized by adopting ultraviolet lamp tubes with different wavelengths and respective functions, can be used for sterilizing and disinfecting, and intensively destroying various organic matters, and can maximally provides convenience, so that users can design dispelling parameters for analyzing samples for the users, the dispelling effect can be furthest improved, the dispelling requirement for different samples can be met, and the operation is simple.

Description

technical field [0001] The invention relates to the field of ultraviolet digestion, in particular to a wavelength-controllable ultraviolet digestion method. Background technique [0002] Ultraviolet light is a kind of light wave invisible to the naked eye, which exists outside the ultraviolet end of the spectrum, so it is called ultraviolet light. According to different wavelength ranges, it is divided into three bands: A, B, and C, and the components of substances digested in each band are different. [0003] Before the samples used in scientific research, medical treatment and environmental monitoring are analyzed, most analytical techniques require pretreatment of the samples, such as organic molecules in the samples will interfere with the determination of heavy metals, especially for voltammetric measurements and spectroscopic Photometric ICP and AAS measurements are very noisy. In order to eliminate interference, currently popular digestion methods include acidificat...
