Abstract

The invention relates to a method for detecting hydroquinone in compost on line, which comprises putting a biosensor in measured solution, utilizing an electrochemical analyzer to analyze current variation data which are adopted by the biosensor, getting response current change characteristic values, response current stabilization time and steady-state current values, outputting the parameter values in a neural network analysis apparatus, and getting the concentration value of hydroquinone after analyzing and calculating. The invention also relates to an on-line detection system which is used in the detecting method, which comprises a three-electrode device, an electrochemical analyzer and a neural network analysis apparatus, wherein the three-electrode device is connected with the electrochemical analyzer, and the electrochemical analyzer is connected with the neural network analysis apparatus, the three-electrode device utilizes a carbon paste electrode which decorates a laccase-Fe3O4 magnetic nano-particle cross-linking body to a working electrode. The one-line detection method and the on-line detection system have the advantages of convenience, high effective, sensitivity, strong anti-interference capability, low production cost and the like.

Description

technical field [0001] The invention relates to an online detection method and system of hydroquinone, in particular to a method and system for detecting hydroquinone by using a biochemical electrode and a neural network model. Background technique [0002] Phenolic substances are very important basic raw materials and by-products in the large-scale organic chemical industry. They exist widely in the environment, are difficult to be degraded biologically or abiotically, and are highly toxic. As a recognized harmful substance, phenol has a great impact on human health and the environment. In the municipal solid waste composting system, there are a variety of phenolic pollutants, and the composting bacteria can secrete various enzymes such as lignin peroxidase, manganese peroxidase, laccase and phenoloxidase, which can Catalyzes the detoxification and oxidation of phenolic substances. Therefore, it is necessary to monitor and control the phenolic substances in the composting...
