摘　　要：含盐量检测传感器对于快速和准确地检测溶液含盐量具有重要意义,特别是对于高海拔复杂环境下电力设备外绝缘的盐密度监测。传统检测方法通常存在操作复杂、检测时间长、灵敏度低等缺点,难以满足现代工业生产的需求。为了改善这一问题,文章提出了一种新型的表面等离子体共振(SPR)传感器,该传感器结合了金(Au)和银(Ag)的双金属层优点,以及二维材料MXene、二硫化钨(WS_(2))和黑磷(BP)的独特性质,如高导电性、亲水性、优异的热稳定性和吸附能力。通过优化传感器的各层结构,进而对比传感器不同金属结构的共振光谱检测灵敏度,结果表明这种双金属层(Au/Ag)/MXene/WS_(2)/BP结构传感器具有高达200°·RIU^(-1)的灵敏度。该传感器具有更强的检测能力,因此能够准确、快速地检测溶液含盐量,对环境保护、资源利用和安全生产提供有力支持。Salt content detection sensors are of great significance for the rapid and accurate detection of solution salt content,especially for monitoring the salt density of external insulation in power equipment at high altitude complex environments.However,the traditional method usually has the shortcomings of complex operation,long detection time,and low sensitivity,which makes it difficult to meet the needs of modern industrial production.To improve this problem,we propose a novel surface plasmon resonance(SPR)sensor that combines the advantages of bimetallic layers of gold(Au)and silver(Ag)with the unique properties of two-dimensional materials MXene,tungsten disulfide(WS_(2))and black phosphorus(BP),such as high electrical conductivity,hydrophilicity,excellent thermal stability,and adsorption capacity.By optimizing the structure of each layer of the sensor and comparing the sensitivity of resonance spectra of different metal structures of the sensor,the results show that the bimetallic layer(Au/Ag)/MXene/WS_(2)/BP structure sensor has a sensitivity of up to 200°·RIU^(-1).The sensor has a stronger detection ability,so it can accurately and quickly detect the salt content of the solution and provide strong support for environmental protection,resource utilization,and safety in production.
