Description
Technical Field
The invention relates to a device for detecting and identifying chemical substances of underwater micro-traces, belonging to the technical field of underwater chemical detection.
Background
With the gradual and deep exploration of the sea by human beings, underwater explosives (such as abandoned underwater unexploded ammunition, mines and the like), chemical poisons and other underwater dangerous chemicals form a serious threat to the life safety and the living environment of human beings. Due to the complexity and the concealment of the underwater environment, the detection and the removal of dangerous chemicals have certain difficulty. At present, detection methods such as sound, magnetism and light are generally adopted for underwater detection and identification, the methods all belong to physical methods, detection and identification of targets are carried out through the shapes, materials and the like of the targets, the detection and identification often depends on experience of people, the detection and identification false alarm rate is high, whether the targets contain corresponding chemical substances cannot be determined, and the autonomous identification capability is insufficient.
According to related researches, chemical substances contained in the dangerous chemicals (such as explosive components contained in underwater explosives and the like) are inevitably diffused to the external environment through infiltration and leakage, so that the detection and identification of the underwater dangerous chemicals can be carried out by using a chemical detection method in addition to a conventional physical detection and identification method. Since the amount of chemicals that bleed out is extremely small, detection and identification of trace amounts of hazardous chemicals in water is required to be accomplished using trace amount detection techniques. The conventional micro-trace chemical detection technology mainly comprises an ion mobility spectrometry method, a fluorescence analysis method, an electrochemical method, a surface acoustic wave method, Surface Plasmon Resonance (SPR) and other methods. Compared with the detection technology based on SPR, the ion mobility spectrometry has the advantages that the sensitivity is low, the selectivity is not high, and the problems of environmental pollution caused by the fact that radioactive substances are used as ionization sources exist; compared with a detection method based on SPR, the fluorescence analysis method has the advantages that the sensitivity is equivalent, but special fluorescence labeling is carried out on molecules to be detected, and the expandability of a detection target is poor; the electrochemical method has the advantages of good selectivity and low power consumption, but has lower detection sensitivity compared with other methods; the surface acoustic wave method has comparable selectivity to the detection method based on SPR, but has lower detection sensitivity. In view of the development of foreign micro-trace underwater detection technology, two detection methods, namely fluorescence analysis and surface plasma wave resonance, have high sensitivity and better comprehensive performance, and are two main methods adopted in the current underwater high-sensitivity detection research. Because specific chemical substances are detected, the chemical detection method can more accurately determine what the detected object is than a physical detection method, so that the chemical detection method is a potential method beyond the traditional physical detection method for detecting and identifying underwater dangerous objects, a new means can be added for underwater perception, and the autonomous identification capability is improved.
In a gas environment, some chemical detection devices or chemical sensors for harmful gases and dangerous objects, such as sulfur dioxide sensors, explosive detection devices, etc., have been provided, and have some applications in practice. However, at present, fewer chemical detection devices or chemical sensors for underwater dangerous chemicals are available, and a few of chemical sensors for in-situ detection are common, and mainly used for detecting marine chemical substance components and analyzing and researching marine environments. However, these current chemical sensors or detecting devices only aim at a single chemical substance, that is, each detecting device or sensor can only detect one chemical substance, and different chemical sensors and chemical detecting devices are needed for detecting different chemical substances, so that the expansibility is not enough.
