Problems solved by technology

There are many factors that affect the desorption of nanobubbles, including electrolyte (type, concentration), distance between electrodes, power supply (voltage, current, power), time, etc. There is no device that can fully adjust and record these parameters
This leads to poor reproducibility of nanobubble desorption results in both research and applications

Embodiment 2

[0021] Example 2: Evaluation of the antifouling effect of nanobubbles on the surface of stainless steel

[0022] The surface in the embodiment is made of stainless steel (316L) and made into a circular sheet with a diameter of 1 cm and a thickness of 1.5 mm. The biological pollutant was 131I-labeled bovine serum albumin. The amount of protein adsorbed on the stainless steel surface was determined by measuring the radioactivity with a γ-counter (SN-967, Shanghai Rihuan). For the convenience of implementation, in the device of this embodiment, Beijing Liuyi electrophoresis instrument (DYY-2C) is used as the power supply for the adjustable constant power supply, and it is set to a constant voltage mode with a voltage of 2V. Place the two stainless steel sheets on the electrodes A and B respectively, adjust the distance between the electrodes to 1.00mm according to the above method, and drop the electrolyte solution (phosphate buffer, pH7.4, 0.05M). Connect the circuits α-A and ...

Abstract

A device for preparing nanobubble and evaluating anti-pollution function thereof comprises an adjustable constant power source [9] and a bracket structure. The bracket structure adopts insulation material for manufacturing an upper panel and a lower panel. Two panels are fixed in parallel by an insulation material support column [3]. One panel is taken as a base panel [2]. A terminal electrode (A,B, C) is fixed on the base panel [2]. The terminal electrode is composed of a metal electrode washer [6] and conducting wires. The other panel is taken as an upper panel [1]. The other terminal electrode (alpha, beta, gamma) is fixed on the upper panel [1]. The terminal electrode is composed of a knurled nut [7] and an electrode screw bolt [4] which has graduation mark on the side surface. An adjustable constant power source [9] is respectively with the electrodes at the two ends. The device of the invention has the advantages of simple structure, convenient operation, capability for realizing the repeatable and adjustable nanobubble preparing, and capability for accurately evaluating the anti-pollution function.

Description

technical field [0001] The invention relates to a device for preparing nano-bubbles by means of an electrochemical method and for evaluating the anti-adsorption effect of the surface thereof, in particular to repeatable quantitative nano-bubble preparation for controlling the degree of biological pollution such as proteins. Background technique [0002] Protein adsorption / desorption is also a ubiquitous and very complex natural phenomenon. Preventing the non-specific adsorption of proteins has always been a major challenge in the research of colloid and interface science. During food processing, the inner surfaces of machinery are exposed to biological media and are often contaminated by non-specific adsorption of biomacromolecules such as proteins. Protein adsorption and subsequent microbial growth seriously endanger food hygiene and safety. On ship surfaces and screens, the adhesion of biomolecules and microorganisms can lead to adverse consequences, such as clogging the ...
