Rapid detecting sensor for microcystins

Abstract

The invention discloses a rapid detecting sensor for microcystins. The rapid detecting sensor utilizes a photochemistry polymerization method or an electrochemical polymerization method to synthesize a molecularly imprinted membrane, so that the combining capacity is improved, the delay time is reduced, and the specific adsorption capacity is strengthened; meanwhile, a Lamb wave piezoelectric membrane is utilized as an effector of the sensor, so that the sensitivity of the sensor is improved, the stability is increased, the cost is reduced, the performance of the sensor is strengthened, the trace detection of the microcystins is realized, and thus the rapid detecting method for the microcystins, with high sensitivity, rapidness, low cost and low operation requirements, is established.

Description

technical field [0001] The invention relates to the field of microcystin sensors, in particular to a rapid detection sensor for microcystins. Background technique [0002] The middle and lower reaches of the Yangtze River is one of the areas where freshwater lakes are concentrated in my country. In the past few decades, human activities have had a great impact on the lake ecosystem in this area. The most prominent is the increasing eutrophication of suburban lakes. Lakes, reservoirs and rivers receive excessive nutrients such as nitrogen and phosphorus, which changes the ecological structure and function of the water body, resulting in the abnormal growth of algae, especially cyanobacteria, and the phenomenon of cyanobacteria blooms. The frequent occurrence of harmful algae blooms caused by the aggravation of eutrophication in water bodies has become an environmental problem of general concern. When the cyanobacteria bloom is severe, it not only affects human senses and des...
