Embodiment 1

[0030] 1. Mix 3g of 2-methacryloyloxyethylphosphorylcholine (MPC) with 7g of butyl methacrylate (BMA) to prepare a solution, and add azobisisobutyronitrile (AIBN) into the solution as a polymerization initiator The polymerization reaction was carried out at 65° C. and argon was used as the protective gas. The polymerization product was precipitated and separated with ether solvent, and dried in vacuum for 24 hours to obtain PMB solid.

[0031] 2. Take 1.00 g of the PMB polymer obtained in the above steps, and prepare it into a 1% ethanol solution by mass percentage.

[0032] 3. Take a water quality monitoring probe and clean it with ultrasonic cleaning. Immerse the probe in the polymer solution for 30 minutes and take it out. After the solvent evaporates, clean the probe with absolute ethanol and distilled water, and dry it in nitrogen.

Embodiment 2

[0034] 1. Synthesize PMB according to the method in Example 1 and be prepared with a 1% aqueous solution by mass fraction, place the semipermeable membrane material in the polymer solution and soak it for 30min, then take it out, and in a 3% sodium chloride solution by mass fraction Preserve by soaking in medium. During use, the semi-permeable membrane material can be processed into a shape suitable for the probe, and then covered and fixed on the surface of the probe.

Abstract

The invention discloses a process for preparing a probe for monitoring water quality of a bionic coating containing phospholipid polymers in real time. The process comprises the steps of synthesizing polyquaternium-51 (p-methyl benzaldehyde (PMB)), and then preparing the probe with a PMB antifouling coating for monitoring the water quality. By virtue of the technical scheme provided by the invention, the operation is simple, the cost is low, the organism adhesion of the probe for monitoring the water quality can be effectively inhibited, and the maintaining cost of the probe can be reduced for a water quality monitoring system.

Description

technical field [0001] The invention belongs to the field of environmental monitoring, and in particular relates to a preparation process of a water quality real-time monitoring probe containing a phospholipid polymer bionic coating. Background technique [0002] In today's serious environmental pollution, the quality inspection of water resources has become a very important task. The water environment detection in many areas is mainly chemical, that is, manual regular (or irregular) on-site sampling, testing, and water quality analysis. This method has the disadvantages of heavy workload and strong randomness, and it is difficult to comprehensively and accurately Reflect water quality and its changes. Therefore, people began to consider using a real-time water quality monitoring system to monitor water quality more comprehensively and avoid the above-mentioned deficiencies. The system is mainly composed of a monitoring center and several fixed monitoring stations. The fixe...
