Title:
CU2+ CONCENTRATION MEASUREMENT DEVICE AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/248669
Kind Code:
A1
Abstract:
Disclosed are a Cu2+ concentration measurement device and a preparation method therefor. The device comprises an optical fiber sensor (10), a broadband light source (20) connected to one end of the optical fiber sensor (10) by means of an optical fiber, and an optical fiber spectrometer (30) connected to the other end of the optical fiber sensor (10) by means of an optical fiber, wherein the optical fiber sensor (10) comprises a biconical optical fiber structure (11) and a polymer film layer (12) coating the surface of the biconical optical fiber structure (11), the polymer film layer (12) is an n-layer film of sequentially alternating modified carbon nanotube layers and polyacrylic acid layers, the biconical optical fiber structure (11) is formed by cascading two micro-nano optical fibers, and the micro-nano optical fibers are prepared by tapering single-mode optical fibers. The Cu2+ concentration measurement device is easy to carry, and the method for measuring the concentration of Cu2+ by using the Cu2+ concentration measurement device is simple and convenient to operate, and has low costs and high sensitivity.
