Due to the severe dangers of copper on human health, development of identification and measurement copper methods in aquatic environments as well as prevention transfer methods of these substances to water resources have received much attention. Among of this expansion, rapid, simple, safe, sensitive and economically viable detection methods are more considerable. In this paper, the sensor activity of the poly(amidoamine) dendrimer containing eight methoxy groups modified with naphthalimide fluorescent derivative is studied. The sensor potential of dendrimer-naphthalimide fluorescence was evaluated in various solvents with different polarities, and results indicated that the detection of cuprum cations (Cu) is possible at low concentration. Also, the fluorescence properties of dendrimer-naphthalimide system are measured in the presence of diverse metal cations. In light of above, from the obtaining results, it can be concluded that dendritic sensor can be used as a feasible method to detect of copper in water samples in low concentrations.
由于铜对人类健康的严重危害，开发识别和测量水生环境中铜的方法以及防止这些物质向水资源转移的方法已经引起了广泛关注。在这种扩展中，快速、简单、安全、灵敏和经济可行的检测方法更为重要。在本文中，研究了含有八个甲氧基基团的聚（酰胺-胺）树枝状大分子修饰萘酰亚胺荧光衍生物的传感器活性。在不同极性的各种溶剂中评估了树枝状大分子-萘酰亚胺荧光的传感器潜力，结果表明可以在低浓度下检测铜离子（Cu）。此外，还测量了树枝状大分子-萘酰亚胺体系在存在多种金属阳离子时的荧光性质。综上所述，从获得的结果可以得出结论，树枝状传感器可以用作检测低浓度水样中铜的可行方法。
