ABSTRACT A new category of thermally stable hybrid polyarylidene(azomethine-ether)s and copolyarylidene(azomethine-ether)s (PAAP) based on diarylidenecycloalkanones has been synthesized using solution polycondensation method. For potential cationic sensor development, a thin layer of PAAP onto a flat glassy carbon electrode (GCE, surface area: 0.0316 cm2) was prepared with conducting nafion (5%) coating agent to fabricate a sensitive and selective arsenic (III) [As3+] ion in short response time in neutral buffer system. The fabricated cationic sensor was measured the analytical performances such as higher sensitivity, linear dynamic range, detection limit, reproducibility, and long-term stability towards As3+ ions. The sensitivity and detection limit were calculated as 2.714 μAμM−1cm−2 and 6.8 ± 0.1 nM (SNR of 3; 3N/S) respectively from the calibration curve. This novel approach can be initiated a well-organized route of an efficient development of heavy selective arsenic sensor for hazardous pollutants in biological, environmental, and health care fields. Real sample analysis for various environmental sample was performed with PAAP-modified-GCE.

热稳定的杂化聚亚芳基（偶氮甲醚）聚合物（PAAP）：一种超灵敏的砷（III）传感器方法

摘要 采用溶液缩聚法合成了一类基于二亚芳基环烷酮的新型热稳定杂化聚亚芳基（偶氮甲碱-醚）和共聚亚芳基（偶氮甲碱-醚）（PAAP）。对于潜在的阳离子传感器开发，在平坦的玻璃碳电极（GCE，表面积：0.0316 cm2）上制备了一层薄薄的 PAAP，并用导电的 nafion (5%) 涂层剂来制造敏感和选择性的砷 (III) [As3+]离子在中性缓冲系统中的响应时间很短。测量了制备的阳离子传感器的分析性能，例如更高的灵敏度、线性动态范围、检测限、重现性和对 As3+ 离子的长期稳定性。灵敏度和检测限计算为 2.714 μAμM-1cm-2 和 6.8 ± 0.1 nM（SNR 为 3；3N/S) 分别来自校准曲线。这种新颖的方法可以为生物、环境和医疗保健领域的有害污染物的重选择性砷传感器的有效开发开辟一条组织良好的路线。使用 PAAP-modified-GCE 对各种环境样品进行实际样品分析。
