A novel polymeric membrane sensor was developed by using 2-hydroxyethyl acrylate, trimethylolpropane triacrylate, (3-mercaptopropyl)trimethoxysilane, and poly(ethylene glycol)diacrylate for As(III) determination. Various parameters, like the pH, response time, the foreign ions, and concentration effects were investigated for deciding the optimum working conditions of the polymeric sensor. As a result of this investigation, the optimum pH was found to be 2, and the response time was found to be 30 s. The linear range of the sensor was 6.65 × 10 - 3.99 × 10 mol L (0.50 - 2.99 μg L) with a detection limit of 2.33 × 10 mol L (0.18 μg L). Soy flour and well-water samples were successfully analyzed with the developed sensor. The sensor can be used at least 100 times after regeneration. It could be reused by washing with purified water and showed good stability for 6 months.
通过使用丙烯酸2-羟乙酯、三羟甲基丙烷三丙烯酸酯、（3-巯基丙基）三甲氧基硅烷和聚乙二醇二丙烯酸酯开发了一种新型聚合物膜传感器用于测定As(III)。研究了各种参数，如pH值、响应时间、外来离子和浓度效应，以确定聚合物传感器的最佳工作条件。作为该研究的结果，发现最佳pH值为2，响应时间为30秒。该传感器的线性范围为6.65×10⁻³ - 3.99×10⁻⁵ mol/L（0.50 - 2.99 μg/L），检测限为2.33×10⁻⁵ mol/L（0.18 μg/L）。用所开发的传感器成功分析了大豆粉和井水样品。该传感器再生后至少可使用100次。通过用纯净水洗涤可以重复使用，并且在6个月内显示出良好的稳定性。
