A selective and sensitive chemosensor, based on the 2(4-hydroxy pent-3-en-2-ylideneamine) phenol (HPYAP) as chromophore, has been developed for colorimetric and visual detection of Ag(I) ions. HPYAP shows a considerable chromogenic behavior toward Ag(I) ions by changing the color of the solution from pale-yellow to very chromatic-yellow, which can be easily detected with the naked-eye. The chemosensor exhibited selective absorbance enhancement to Ag(I) ions in water samples over other metal ions at 438 nm, with a linear range of 0.4-500 μM (r(2)=0.999) and a limit of detection 0.07 μM of Ag(I) ions with UV-vis spectrophotometer detection. The relative standard deviation (RSD) for 100 μM Ag(I) ions was 2.05% (n=7). The proposed method was applied for the determination Ag(I) ions in water and waste water samples.
基于 2(4-羟基戊-3-烯-2-亚胺基)苯酚(HPYAP)作为生色团，开发了一种选择性和灵敏的化学传感器，用于比色法和目视检测 Ag(I)离子。HPYAP 对 Ag(I)离子表现出相当大的显色行为，溶液的颜色从浅黄色变为非常鲜艳的黄色，用肉眼很容易检测到。该化学传感器在 438nm 处对水样中的 Ag(I)离子表现出选择性的吸收增强，对其他金属离子的线性范围为 0.4-500 μM(r(2)=0.999)，用紫外可见分光光度计检测到 Ag(I)离子的检出限为 0.07 μM。对于 100 μM Ag(I)离子，相对标准偏差(RSD)为 2.05%(n=7)。该方法已应用于水样和废水中 Ag(I)离子的测定。
